Heater core

Showing 4 out of 4 Posts
Question From alexonline on Heater core

Hello Everybody!
I have a Mitsubishi lancer 1998 sedan.
The heater core looks to be already bypassed and yet my car is leaking inside.
Iv'e looked online and can't find any other reason why the car would be leaking and I mean really leaking like flooding my car to the point where I came back after three weeks and a colony of mold infiltrated my car :(

I took photos ( 3 photos attached ) of the bypass and the passenger side as well.





Any suggestions? I would really appreciate the help :)

Response From Hammer Time

If the heater core is already bypassed, then it can only be either condensation not draining from the AC or rainwater leaking into the car.

The place where that is leaking tends to point to a rainwater leak.

Response From Tom Greenleaf Top Rated Answer

Sorry this is so wide - I can't touch
the pics off the web of this.


Yes - could be non engine coolant and suggested
testing core alone with pressure to rule out
plain water from another source that Hammer Time
just suggested.


Still and would plan on removing seats and carpet OUT
for this to totally dry out when fixed as it really wont
dry enough on its own well.


Any which way it's going to be some serious
work,


T

Response From Tom Greenleaf

? First I'd pressure up just heater core to verify. That doesn't look like mold and a coolant mix wouldn't support mold so it's rust looking to me. Make sure but bet it the core is wasted badly, possibly from using straight water but can for any reason.

^^^^ Direct pic may not show?


Replacement of core is almost always a real fussy job. So is totally cleaning all that up so there's no moisture left - carpet out would be best.


Parts not so bad just lots of time, labor and risks or breaking small parts could be real hard to fix or replace if bad enough.


At a glance this is a commitment for this car and would think about if you should at all or change out cars for another - your call as it looks like rust to me bad enough that inside engine could be just as bad?

Car Heater doesn't work..

Showing 6 out of 16 Posts | Show 10 Hidden Posts
Question From BNK3R on Car Heater doesn't work..

I changed the thermostat and nothing.
Cleaned out the hoses and still nothing.

Don't know much, but the hose that is connects the radiator to the engine gets hot, but the hose connected to the thermostat never get hot.

Any idea?

Mitsubishi 2005

Response From Hammer Time

With the engine at full operating temp, locate the 2 heater hoses where they go into the firewall and feel them to see if they are both hot to the touch. If not too hot to hold, then you have to look at the actual engine temp and if that is up, if it is, then your looking at a restricted heater core or poor circulation for another reason.


How about a model and engine size on that car too.

Response From BNK3R

Thanks for the reply.

I think it's a 16 valves L-4 engine.
2005 mitsubishi eclipse spyder.

But like I said, one of the hose got really hot and the other one didn't at all.
Don't think it's poor circulation. I feed(?) water into one of the hose and it went out the other hose.
Also the hose was EXTREMELY rusty (the coolant was coffee-ish brown).

Restricted heater core?

Response From GC

In your original post, you talked about the upper and lower radiator hoses (i think). Hammer Time is talking about different hoses. Re-read his post. These hoses run through the firewall.

Response From BNK3R Top Rated Answer

Yeah I miss read that. Sorry, Hammer Time.
Gonna check the hose when I be able to.


also, when I took the thermostat out and put water in the radiator (to check if the water pump is working) the hose that wasn't getting hot got hot.

So, I guess I'm going to check if the thermostat is working (It's brand new), then check heater core and the hose connected to the firewall.


I have a new problem, by the way.
I was trying to tighten the bolts on the thermostat cover and one of the bolts broke off. Half the tread is still in engine. What is the best way to get it out?
And is the best way to check if I have a faulty thermostat is by putting it inside boiling water and check if the thermostat valve pops up(open) or not?

Thanks for the help so far guys, really appreciate it.

Response From Hammer Time

The best advice i can give you is to step away from this car and have it towed to a competent shop. All you are doing is creating more new problems without resolving any of the old ones.

Response From BNK3R

Can't learn anything if I just give up and let someone else do my job.
Really appreciate the help, but please don't try to discourage me.

Response From Hammer Time

I'm not here to encourage you to do even more damage. I'm here to give you good advice and in this case it would be to let the professionals do it.

I'd love to perform open heart surgery too......... Do you think I can learn how in a forum?

Response From BNK3R

So if a person brings his/her car to you with the same problem I have (broken bolt), what would you do to the car?

Response From Hammer Time

Get the bolt out without destroying the housing as you will be doing if you try it.

Response From BNK3R

And how would you get it out w/out destroying anything?

Response From Hammer Time

Go ask your local mechanic to show you.

This question is done.

Response From Hammer Time

This car has a heater control valve under the dash on the passenger side that shuts off the coolant circulation. You need to check that out.




Response From BNK3R

And in case it isn't that, what could be another problem?

Response From Hammer Time

Your heater core isn't getting flow through it so either it is shut off or blocked.

Response From Tom Greenleaf

"Also the hose was EXTREMELY rusty (the coolant was coffee-ish brown).

Restricted heater core? "


Flush that coolant out good for known good new and specifically flush the heater core and radiator observing full flow. Yes, that would clog a heater core and may not flush out till you try. Whatever is causing that it has to go,

2004 Mtsubishi Eclipse - Heater blows cold air while sitting idle.

Showing 2 out of 2 Posts
Question From angim on 2004 Mtsubishi Eclipse - Heater blows cold air while sitting idle.

My daughter has a 2004 Mitsubishi Eclipse and when she starts the car on cold mornings the heater blows cold air and dosen't get warm until she is driving it and it gets about 2000 RPM's. She has had the Thermostat changed and the system flushed, this helped for a little while and went back to the same problem. She was having to add a little coolant sometimes so she had it checked again and they found a hose the was loose and leaking a little, this helped for just a short time and back to the same problem. We have found that if you squeeze one of the hoses while the car is running the heater will blow hot air just for a short time. Someone told us that the system might have air in it to park it on a hill so that the radiator cap was higher that the heater core and remove the cap and let the car run for a while to see if the air would come out, did this and the heater was hot at the time but when she got back in it later it was cold again. It is not loosing any fluid now and does not run hot....Any suggestions?

Response From Hammer Time Top Rated Answer

Sounds like the heater core is plugged up and will have to be replaced.

Question From tyler9999 on No Heat in 2001 Eclipse GT

I have no heat coming out in my 01 eclipse gt? never used it before as I bought the car used in sw florida and never had the need to turn it on until now. Can anyone tell me why and how to repair?
Thank you much!
2001 Mitsubishi Eclipse GT / 3.0 liter V6 engine / 111,000 miles

Response From steve01832

Need info such as: is the fan motor blowing, cold air from ducts, overheating?

Steve

Response From tyler9999

Steve:
Yes the fan motor is blowing just fine, but just cold air. The car is not over heating at all. Temp gauge is right where is is supposed to be, and car is not running hot or over heating. I thought maybe from lack of use the thermostat was stuck or shot? Could this be the issue?
Thanks very much
Tyler

Response From steve01832 Top Rated Answer

Tyler, what you can try is to let the engine get to normal operating temp. Carefully grab the heater hoses, one at a time. If they are both hot, you may have a problem in the ducting of the heater module. If one is hot and the other is cold, you have a restricted heater core. Perform this test first and post back with the results.

Steve
