Question From broncobob552002 on 1999 ram 1500

i have a 1999 ram 318 the radiator has back pressure before the thermostat opens

Response From broncobob552002

thx for the reply my radiator has back pressure enough to poor out the overflow bottle (cold water) and temp guage will over heat until thermostat opens i've replaced thermostat and rad cap top hose waterpump hope you can help and thx again (oh I have new radiator too)

Response From GC

So if you start the vehicle cold, does the upper radiator hose stay cool even when the temp gauge rises above normal? Need to get a infrared thermometer and check against gauge and verify temp that tstat opens. A pressure tester would be very helpful. When does it overflow?

Response From Tom Greenleaf Top Rated Answer

System has to be known full. Air or vapor anywhere or anyhow getting in to system will blow out that bottle like a real overheat which your gauge shows as well. Probably is.

This can happen from a head gasket failure frequently the result of your original issue not the cause but doesn't matter now check whole system out and that too,

Response From Hammer Time

So........ what's the issue?

Response From Tom Greenleaf

No issue yet at HT said. T-stat doesn't make or allow pressure, the pressure cap does,

low heat in Dodge Ram 1500 Quad

Showing 2 out of 2 Posts
Question From dhaywood on low heat in Dodge Ram 1500 Quad

I have a 2001 Dodge Ram 1500 5.9L. I have had trouble for several years with low heat at idle and low speed. The temp goes up if you race the engine or drive at highway speed. I have replaced the thermostat and radiator cap. I have flushed the heater core in both directions. The water was clear with no apparent obstructions. The temperature of the input line to the core shows 165 degrees and the output side shows 148. I placed an HVAC thermometer in the vent and it reads 135 @ fast idle and drops to 120 @ low idle. I did take it to the Dodge dealer for an unrelated issue and mentioned the low heat problem. The mechanic said he thought he knew what the problem was and afterward it worked for about a year. Unfortunately I don't know what he did but I heard him say something about the vacuum lines. I have looked at the vacuum layout in the Haynes manual and don't see anything that looks like it could cause the problem. DON'T KNOW WHAT ELSE TO TRY. I tried posting this earlier and I thought it worked, only now I can't locate anything. So I apologize if this shows up twice.

Response From Tom Greenleaf Top Rated Answer

Some questions and thoughts:

*Does temp gauge for engine stay steady once warmed up? It shouldn't fluctuate at all if normal.

* If it fluctuate it points to coolant passing thermostat even if just slightly - new one or not. Upper hose should remain cold to the touch for fair while as engine warms up and stay there.

RPMs make a difference. Two things happen, 1, the flow would naturally increase, 2, the amount of heat engine generates would go up as well.

Temp at thermostat cover should be very close (infrared test) as the thermostat's rating - typically close to 195F full operating temp.

Your observed temps all seem low to me. A quick look up suggests OE thermostat should be 192F..........
~~~~~~~~~~~~~~

Application:
OE recommended temperature
Notes: 192 degrees F ~~~~~~~~~~~~~~~~~~~~ Your results seem more like a 180F thermostat is in there or it's letting coolant pass as said. Probably not the issue but antifreeze concentrations higher than 50% or would show -34F protection can lack heat transfer ability but none of your observed temps were quite high enough IMO, T

dodge truck is overheating, heater won't blow hot air

Question From dodge fixer on dodge truck is overheating, heater won't blow hot air

Hello folks
I have a 2002 dodge ram 1500 v8 4.7 ltr. replaced the radiator and thermostat, still overheating, and the heater will only blow hot air for a short period of time. Any advice would be greatly appreciated. blower still works just air gets cold.

Response From Loren Champlain Sr

Did you replace the radiator and t-stat because it was over-heating to begin with? You may have an air pocket in the heater core (assuming it was getting hot, before). Although rare on this engine, you may also have a head gasket leaking hot exhaust gasses into the cooling system which would 'super-heat' the coolant quickly and cause the heater problem. Assuming the engine is no longer over-heating, I would suspect an air pocket. If so, allowing the engine to run long enough for the t-stat to open and close several times will normally work the air out. I've had to raise the front of the vehicle (so any trapped air goes toward the radiator) in order to work out the air. Good luck. Have a great weekend (after you get it figured out). :)

Response From dodge fixer

thanks for the info i'll try anything at this point!!!

Response From Loren Champlain Sr

Dodge fixer; It is very common for DIYers to install the t-stat upside-down. You may want to check, just to be sure. If you did, don't feel bad. We've all been there. That's a part of learning. Another trick, which Tom had posted in another thread, is to drill a 1/8" hole in the flat area away from center on the t-stat flange. (wish I could add a drawing). This allows a bit of flow, even when the stat is closed, and aids in bleeding the air.

Response From Tom Greenleaf

http://www.aa1car.com/library/elements/thermostat_bleedhole.jpgLookie what I found out there! The light dot (is actually a tiny barbell) is called a "jiggle valve" used in some thermostats to assist in getting air out but not allow too much bypass for poor heat or slow warmups. Hard to find these and if you have one the dot goes up top - sprind end always toward block. You can drill a tiny hole for serious problem engines to allow easier air removal. Some will have an notch already cut in which goes un-notices to do the same thing. If they work then filling a system will be close to purged but still a wait for air to pass by the closed thermostat.

As Loren said - thermostat must be known installed properly. They will misbehave if backwards and then might open after too hot and behave a short time and repeat that. Many simply won't fit backwards and can't say for this application.

Added note: VERY few thermostats have been truly defective in my findings. A new one coupled with a new radiator that still overheats suggests air involvement for any reason.

Way out there is pump that doesn't pump (corroded impeller) - not common at all but has been reported - not this engine BTW. Those usually dislike low rpm at first.

Keep at it and checking. Avoid overheats,

T

Response From Loren Champlain Sr Top Rated Answer

Okay, where are you finding all these cool pics? That's cheating!

Response From dodge fixer

thanks again have checked out these suggs. but still running hot, now i am looking for the heater control valve which could possibly be stuck?? sound like a possibility to you guys?

Response From Loren Champlain Sr

Sorry, your truck doesn't use a "heater control valve". And, that wouldn't cause an overheating condition, anyway.
You can check for a head gasket leak a couple of ways. There is a chemical called "Block Check" available at NAPA or CarQuest stores. The chemical will turn from blue to yellow if exhaust gasses are present in the cooling system. The other way would be to "sniff" the cooling system with a gas analyzer for hydrocarbons. Have you visually checked the t-stat to make sure it is properly installed? (see Tom's earlier post; It shows a t-stat, right side- up). As new as your vehicle is, I doubt that it could be a plugged radiator, but in this world, anything is possible.

Response From Tom Greenleaf

Hmmm? Agree with Loren about the exhaust gasses are still getting in. If this was ever really filled properly and usually if heater works you are approaching full of coolant and still overheating with the no heat problem then it's probably boiling hot and the air (vapor of boiling) doesn't allow heater to work. How overheated does it get? Are you letting it boil right over like a steam kettle and needing to refill again? This should purge out air from a coolant refill on the first cycle and not be fussy as some vehicles are. So far I think this is a head gasket problem and that won't make your weekend!

Heat works on low but not at any other speeds

Question From biloxims on Heat works on low but not at any other speeds

I have a 2002 Dodge Ram 1500 4.7 liter and I relpaced the thermostat and the heat works just fine. I went shopping and then all of sudden the heater stop blowing hot air. It work on low but no other speeds. I replaced the thermostat again and same problem. You think it could be a bad heater core?

Response From Tom Greenleaf Top Rated Answer

Heater core shouldn't have plugged quite that quick. What was the reason for the first thermostat replacement?

If heater worked for a while or before all this then I think you may find it's low on coolant and still settling down purging itself of air. Try to verify it's filled at the radiator or highest hose if no cap on this radiator. Cycles of warm up and cool downs should purge out air and could be low now but was ok for a short time,

T

Response From biloxims

The problem started after I had my intake manifold replaced. The heat was working just fine and then all of a sudden it stopped. I replaced the thermostat and the heat work just fine. After driving vehicle for 2 hrs stopping at multiple stores, the heat stop working again. This time I could some heat on low speed, but nothing but cool air on higher speeds. I repl,aced the thermostat once again and this time nothing. You think it could be I could have an air pocket in the system? or could it be a bad heater core/ radiator. Please help. I am freezeing in my vehicle. I really dont want to share rides with my wife after sharing one car for one month.

Response From Tom Greenleaf

Every time coolant is removed (drained) for any service or repair you have to make sure it's really filled up again. Any air will purge out and if the system is fine the recovery tank would be a correct measure of how full you are but not until all is stable. I don't know how long or who has checked what when things were done to it.

The deal with it working on low fan is there's only so much heat available and blowing more air thru limited warm/hot coolant will blow cooler air if that's the case at all. Just need to know it's full for now.

If the manifold job made a lot of debris scraping gaskets then the heater core might have caught too much and would flush out. I can only guess at what was done already - was it flushed when manifold gasket job was done? Did that solve the problem - a leak or what did that show up as? Serious overheats?

Again - the core wouldn't just plug up so easy or fast in most cases and simple flushing would show how well it can flow thru it. The ones that need to be replaced and don't flush out are usually a crusty build up over some time that just won't move along OR overdoing leak stop additives will plug them up - is that a possibility?

Sorry for lots of questions but need to know the state of the thing right now with the cooling system not just the heater. Does engine run at a steady temp and coolant stays properly filled? That's a good starting point........
