Question From JA5PER5 on REPLACE HEATER CORE

CAN SOMEONE HELP ME I NEED TO REPLACE THE HEATER CORE IN MY 1991 PONTIAC TRANS AM I HAVE 70,000 MILES AND A 350 ENGINE, MY QUESTION IS WILL I NEED TO TAKE OUT THE GAS IN MY AIR COND. SYSTEM TO REPLACE THE HEATER CORE? PLEASE HELP
THANKS

Response From Tom Greenleaf Top Rated Answer

Wish I knew specifics but it's possible you do need to take "evaporator" out at the same time. This would mean recovering existing refrigerant for return later. Use new "O" rings as needed and Nylog or I like pure silicone grease for those. Just a smear!

They are a pill but doable with enough time and patience,

T

Hit back if you need help recharging A/C. It's posted here in good detail anyway at this section - subject line in all caps....

Response From JA5PER5

THANK YOU FOR THE INFORMATION, AND THE DIAGRAMS .YES I STILL DO HAVE THE R12 IN THE SYSTEM I'M NOT SURE IF I NEED TO WORRY ABOUT THE AIR COND. SYSTEM?? I WOULD LIKE TO FIX IT MYSELF AND NOT SPEND THE EXTRA CASH.
THANKS AGAIN

Response From Hammer Time

No, it doesn't appear that you will have to evacuate the refrigerant to remove the heater core.

Response From Tom Greenleaf

You'll know as you get there. Legalities or not just be real careful as if you open a line it can freeze the skin right off you.

Unless you live in the hottest of climates switching to 134a will still work fine or find new R-12 which is out there but does cost more and is restricted to buy,

T

Response From Hammer Time

That was a evap core, I'll get the heater instr.

The heater core is much harder because the dash and console have to be removed.

Response From Tom Greenleaf

Thanks Hammer!

That earns you company stars.......



You can cash those in at the company store and still have nothing but wall paper


T

Response From Tom Greenleaf

To add: Are you still with R-12 or swapped already to 134a? It matters! It's getting hard to find places to help with recovering R-12 and if you are already 134a just use new stuff and take contamination out of the game,

Question From moospis on Replace heater core

Hi all- I need to replace the heater core on a 92 Pontiac Grand Am SE. Where is it located and how would I go about replacing it? Thanks for the help!

Response From Tom Greenleaf Top Rated Answer

That is probably a VERY involved job and if you are up to it I suggest the info available at ALLDATA.com for all the info you will need. Takes a lot of tools and time for most. Don't bother with the store manuals as they just don't go far enough.

We'll try our best if you want to tackle this. Core is exactly at the ends of the heater hoses at firewall, T

Heater Core replacement?

Showing 2 out of 2 Posts
Question From BaB on Heater Core replacement?

My son was told he probably needs a heater core.(car overheating) He has a 1997 Pontiac Grand Am V6.
He just would like a ball park figure approx what this will cost to have it replaced. He has no mechanical skills to try it himself.
We know the labor will be the biggest part of the bill, but 300?500?700?
Trying to see if it's worth fixing.

Thank you for any help.

Response From Tom Greenleaf Top Rated Answer

Unless it's leaking onto floor in car why do you think it needs a heater core? Overheating could be lots of things. The core might be part of the by-pass system of the cooling system and if plugged could effect engine temp.

If not leaking and with cooling system known full - at radiator not just a recovery tank and it can blow heat this isn't causing it to overheat.

I don't know the labor time for this car but I would make sure it needs a heater core first. It's not always so easy to purge cooling system of air to test out the cooling system in general.

Note: A good heater core won't throw heat if coolant is low enough or if the car is overheating it would have hot air boiling thru it which doesn't exchange heat even close to hot water (coolant) in the core,

Question From bhause53 on 2007 pontiac torrent no heat

changed thermostat still has cold air coming out no hot air

Response From Tom Greenleaf

(only 3.4 engine shown for this)
What was wrong with the old thermostat? Nothing by all odds. Check that heater hoses going to core are both hot.

If engine temp is staying normal, coolant know filled and no air pockets you might have a stuck blend door or actuator problem.

It's more likely that engine has overheated, air in cooling system, is running hot, blown head gasket(s) or sealer was used that might have clogged up the heater core,

T

Response From Hammer Time Top Rated Answer

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.
If you find that they are both too hot to hold, then the heat in that vehicle is controlled by a blend door that regulates heated air flow. it is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.
If they are both not too hot to hold on to, then you either have a restricted heater core or the system is not completely full and getting air pockets for some reason.
