89 Acura Integra radiator hose question

Showing 5 out of 7 Posts | Show 2 Hidden Posts
Question From dlmcmurr on 89 Acura Integra radiator hose question

Can anyone tell me which radiator hose goes to the thermostat on this model? I've had the head off and replaced all the hoses at that time. The new hoses look like they fit better in the reversed position relative to the old hoses, but the engine got hot on the first run. That was with the top hose to the thermostat. I did bleed the thermostat housing during refilling. I thought upper hoses always went to the thermostat and someone before me had reversed them?

Thanks,
Dave

Response From Tom Greenleaf

. 1: Thermostat replacement-Integra
***************
Make sure spring end of thermostat is towards engine. There's a lot going on right there and may take a cycle or two to settle down and purge all air out. All the hoses must be right where they belong. This looks like other hoses are part of telling this t-stat when to open and if not all correct there will be problems. When at all possible - match up old hoses to new ones and many need to be cut at one or both ends to match. Everything I could find suggests the upper hose does go from thermostat to radiator directly, T

True: Most thermostats won't go in backwards but some have an "up" side to assist air purging.

Try that site for the diagram.

Heater really should be run when first testing out a cooling system after it's been drained for any reason. Most will blow strong heat when full enough and if not there's still more to go (purging) ..

In a career I haven't seen many new thermostats be totally wrong and the problem. In troublesome cases I will test them in water watching the action work on a stove.

Air is lousy at transfering heat so t-stats can be slow to react to hot air but will in time - usually late. As said some are designed with notches or tiny check valves to allow air past them (must be installed with that "UP")for better self purging but even that is slow.

Keep at it. Air still in system is most likely the trouble so far,

Tom,

Your link didn't work, but it pointed me in the right direction. In the radiator section at the same site, figure 1 shows the hose routing with the lower going to the stat and the upper going to the head. I'll reverse my hoses this evening and try to bleed the system better and see where it goes from here. Hope I haven't cut the one too short!

Thanks,
Dave

Response From Tom Greenleaf

Ok: That's "AutoZone's" parts site. Some, not all when you look for a part will show how it's replaced, located or more about it. Look below when you get a picture of a thermostat for example the look for "repair guides" below that and if there's any further stuff it's hidden there - just a trick to be able to look at stuff.

If you can take pics that's even better so I/we can see just what you are dealing with.

Bleeding: If a plug up high on or near thermostat is there it's for letting air out. If not sometimes you can just remove the highest hose and fill from there and re-attach. Run engine till heater works and upper hose past thermostat is warm to hot and shut if off for a good while. It should be pushing air out to recovery reservoir and when it contracts as it cools can only draw back liquid. Can take many cycles of that to be stabil.

If heater worked before it will work now and when no heat is noted it's frequently because the actual liquid in the cooling system's engine side is still too low unseen at a glance. Understand that the thermostat when closed is not letting air thru it so it must be warm enough to open but don't let it overheat. As said - some t-stat's come with a slot or mini hole to let the air past it when cold but that's still painfully slow and with even minor junk going thru system won't work as it would plug.

Getting air out is not as quick and simple as it looks sometimes. Keep at it and look for the signs of temp stability as the idicator that it's mostly done and would finish the last tidbits of air over use so re-check your coolant level daily for a few days of use is suggested by me anyway.

Good luck - keep trying,

T

Response From dlmcmurr

Tom,

It always bugs me wondering how some suggestions worked out, so I thought I'd tell you how this project ended up now that it's running again and I've semi-caught up some of the other things that got behind.

This started out as project to replace a damaged exhaust valve. The last car head I had removed was in a Vega over 30 years ago, so the DOHC experience was not where I really wanted to start. It all went relatively well. As I said, I had used (obviously faulty) logic to decide the radiator hoses had originally been reversed. I put them back correctly, but things still weren't normal. Got frustrated and went to bed. On a whim, turned on the key the next morning and waited on the gauges to stabilize. Lo and behold, the temp gauge was showing normal after resting all night! Must have damaged it when I was banging the head around. Went out and bought another sending unit and that solved that problem. Once I put the proper Permatex on the head to radiator hose adapter (looks kinda like a smaller thermostat housing) and resisted the urge to tighten it all the way down, that solved another problem. Other little incidentals like the intake cam being one tooth off, a nicked O-ring on an injector (those are hard to find replacements for), etc. kept the job interesting. I enjoy reading and using web resouces to learn how things work, plus I really couldn't afford to replace my 280k+ mileage car right now. I had hoped that new valve stem seals, camshaft seals, and a valve cover gasket would make a significant difference in my oil consumption since they were all leaking, but that has not proven to be the case. Guess that means instead of $350, I should have spent 4 to 5 times that to rebuild the engine, but I was worried that even my $350 would be wasted as I would overlook (or cause) some other major problem. At least this gets it to where I can sell it in good conscience later if I want to. Plus I can buy a lot of oil for $1000.

I appreciate people like you that enjoy helping those of us that have the reasoning power and desire, but lack the practical experience to solve our problems. I try to do the same in other areas where I have knowledge.

Thanks again,
Dave

Response From dlmcmurr

Thanks, Tom. Fortunately, the thermostat only fits in one way, with the spring into the pipe running across the back of the block to the water pump. One thing I forgot to do was open the heater valve to purge that system, too. I'll run it through one more cycle this evening. Guess there's always a chance the new thermostat is bad, but probably I just didn't get enough air out. Is that drawing available somewhere that I can read the labels?

ACURA VIGOR GS 1993 Radiator Fan

Showing 3 out of 7 Posts | Show 4 Hidden Posts
Question From Guest on ACURA VIGOR GS 1993 Radiator Fan

Acura 1993 Vigor GS-Radiator fan comes up after temp shows 3/4th of Temp gauge.Earlier temp never gone up above 1/3rd gauge. Rad Fans comes up but late.
When A/C on it comes up immediately

Response From Tom Greenleaf

Check that coolant is truly filled at the radiator not just the recovery tank. If the temp reading returns to a steady temp when fan is engaged either by forced with A/C request or when it comes on it is late and that would usually be the senser itself or the coolant is low and info to trigger fan is delayed,

T

Response From Guest

Coolant truly filled-not just the recovering tank.
Tem senser was changed but same trouble.
Fan trigger late without A/C request.
With A/C request both fans comes up.
With defrost request Fans do not come up.

Response From Tom Greenleaf

There must be another sensor for the fan - usually near thermostat but I don't know for this car,

T

Response From Guest Top Rated Answer

We changed sensor near thermostat but still problem persists.Any possibility of Fan control switch gonebad and switching at higher temperature than earlier setting? How to test if this problem?

Response From Guest

Hey some body can guide me on this problem,I do not want to go to dealer and spend lot of money and there again not assure of solving problem.

1993 Acura Integra - Keeps Overheating

Showing 2 out of 8 Posts | Show 6 Hidden Posts
Question From croatia84 on 1993 Acura Integra - Keeps Overheating

I have a 1993 Integra 1.8 DOHC. It was driving fine but recently started overheating, i replaced the thermostat, radiator cap and flushed the radiator but still overheats. I don't think it is the water pump because it's not loud and it's not leaking. Also i do not think that it is the head or intake gasket because i am not loosing oil or coolant.

Is there anything else i could try ?

I know it's an old car but i just put all new interior in it, new paint, wheels..... I hope i can save the engine.

Thanks in advance for any help.

Response From croatia84

I also did add water this morning while the engine was still cold and i tried to "burp" the engine by letting it run until air bubble came out.

Response From Tom Greenleaf

I plain can't know the layout of every model of every car but you are nicely invested in this so try like crazy not to let it overheat. You may still have lots of air in it - some are a real pest to "burp" it all out, especially ones with radiator cap that is on the recovery tank. Check level again when cold.

Generally if heater will work you are close or done.

Water pump is a maybe. Some use steel impellers that just don't move enough coolant. If a composite (rot free) impeller probably not that. If return hose or heater is weak pump might cause that.

*Do fans work?
*Heater as said blows warm/hot air well?
*Hard to check but if you continually find level low head gaskets can put higher pressure gasses into cooling system. Can get test strips for evidence or if always low or lower when you check that's on the list. Most will show pressure just by squeezing upper rad hose way too early (don't burn yourself) just with a squeeze you can feel pressure way before it's warmed up enough.

* Will it get too warm just idling or do you have to be driving it? If only while drive fairly fast the air dam under bumper if missing can screw up air flow.

- Careful, but do you feel hot air off the fans?

-- Just some things to consider till the fix is diagnosed,

Response From croatia84

Hey Tom, thanks for the reply.

I tried to burp it out but water in the radiator keeps boiling, so i don't think i will be able to do that.

* Fans do work
* Heater does not blow hot air even when warm, but while i was trying to burp it i did feel it getting warmer
* I can't feel any pressure in the hose even when it's overheating.
* It gets warm either stopped or if driving.

I think i may have a bad radiator, is there an easy way to test it? I fill the radiator up but i do not see water moving or circulating.

Also i added water instead of 50/50 mix would that have any affect ?

Response From Hammer Time Top Rated Answer

You can't do it with the cap off. Fill the system and cap it. run the engine until the thermostat opens and then take it around the block. Shut it off and let it completely cool until dead cold. Open system and top off, repeat process until it stays full and you have heat.

croatia - like HT said this can take several cycles and time to purge air out and take a long time to cool down and repeat as he said. Shops are now using a vacuum thing such that you can do it the first time - I don't own one but they (friends still in biz) can't take all day to purge fussy cars.

Comments on your observations: You don't have heat! If when you flushed it and heater core allowed flow you should and air or overheat would cause no heat or even poor heat from heater.

No pressure! Pressure check it with a real pressure tester and see if it can hold - bet it can't - not a good sign unless it's leaking unseen somehow. Careful if it loses pressure as a cylinder my be full of water! If so then take spark plugs out before cranking or it will hydraulic lock and possible damage. Water may spit out of a plug hole proof of a head gasket problem.

Water only is fine for testing for now but puts you back to needing the protection when stable so gotta learn how to get air out.
You don't need exactly 50/50 but should aim for -20F at least - many full strength antifreeze bottles have the % to add to achieve what. FYI - antifreeze is a lousy product for heat transfer but needed for protecting system. If it gets VERY cold where you are you do want comensurate concentration.

* This has overheated so much now I suspect you have a bad head or head gasket now with this -- what do you think HT? Getting higher on the list of reason this overheats?

Response From croatia84

Thanks a bunch guys, this morning i had decided i will invest another $112 for a new radiator and that solved the problem. I'm not sure if the old radiator was bad or if there was too much air in cooling but problem solved.

Thanks for all the help

Response From Tom Greenleaf

Thanks for reporting your success. $112 for a radiator is chump change really and a good thing for a car of this age. Hope it stays cool and no other problems from overheating

Fuse may be routed thru a relay. Got fix this or your risk wild engine damage. No fan - ov course it will overheat!

94 Acura Legend OVERHEATING!

Showing 2 out of 2 Posts
Question From johnswalley on 94 Acura Legend OVERHEATING!

I have a 1994 Acura Legend LS 3.2 THAT HAS 160K miles and I am having a really bad overheating problem. One day my car will work fine and then the next day the temp guage spikes like crazy. The day it was spiking so bad I had noticed it was doing alot better on the highways doing 60+ but everytime i had a red light or city driving it was overheating really bad. I had already replaced the thermostat when I first bought the car (Mid January) and i used a product called Blue Devil to seal up any gaskets and any other leaks i could possibly have in the cooling system. So where do I go next?


- Could I just bypass my fan switch so that the fans are always opperating?

- Could I just take the thermostat out to have a free flowing system with no obstructions?

- Just give me any suggestion that will work so it can get me back and forth to work!!!!!!!!!!!!!!!!


PLEASE PLEASE PLEASE HELP ME, I AM SOOOOO TIRED OF PUTTING MY HARD EARNED DOLLARS INTO THIS STUBBORN A$$ CAR!!!

Response From Hammer Time Top Rated Answer

i used a product called Blue Devil to seal up any gaskets and any other leaks i could possibly have in the cooling system.

What? Are you kidding me? You think a can of "mechanic in a can" will solve all your problems?

Have it block tested for a blown head gasket and pressure tested for leaks. Now that you've added that junk, you will probably need a new radiator if you didn't already.
