Question From sololoco on heater core dodge durango 1999 4x4

Hi there to all, i am just about to take out the heater core, but i cant see the easy way to do it, is there one?

Response From fordtech Top Rated Answer

there is really no easy way to remove the heater core , a/c needs to be recovered as evaporater needs to be removed with the heater core. fyi not all the aftermarket heat core are the same size as the factory ones. it call for about 5.5 hours to r&r the heater core on this one. good luck

Response From sololoco

OH boyo!!!, that is what i was afraid of,, thanks a lot my good man.

Response From Hammer Time

The whole story is the entire dash has to be removed first and then the entire HVAC housing has to be removed and disassembled.

bypassing a heater core on a 99 Blazer

Question From Heather0507 on bypassing a heater core on a 99 Blazer

I've been having problems with the heater core on my 1999 4wd Chevy Blazer. Just about everyone I've talked to has mentioned removing the entire dash. I've also heard about a temporary fix that requires looping the hoses to the heater core, which bypasses the heater core all together. What is the easieset way to loop the hoses? I don't have the funds right now to replace the heater core, and I'd rather not have to remove the entire dash to loop the hoses if at all possible.

Response From way2old Top Rated Answer

Look under the hood where the hoses go into the firewall. There should be clamps on the hoses. Remove these clamps and the hoses. Place a connector in the 2 hoses that will not crimp and block the flow of coolant. And you have bypassed the heater core. You might need to repair the heater core before long. If you are in a cooler climate, the weather is gonna change soon.

Question From deelo on one last heater core question

so..i got the heater core out finally..thanks to you guys' help, so the hoses were spliced to bypass the old heater core so i take out the splice and now i have two hoses but which goes where, the heater core doesnt seem to be labeled with an in/out or anything? thanks.

Response From steve01832

The order of the hoses doesn't matter. As long as the coolant flows through it you will have heat. When you take the line coupler apart, the hoses should bend towards the appropriate pipe they were originally connected to. But, like I said, it's bidirectional.

Response From Tom Greenleaf Top Rated Answer

Many are different ID hoses and will only go on one way, T

REPLACE HEATER CORE

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

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 Top Rated Answer

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,

i have a 2005 suzuki forenza have the dash including the climate control cluster taken out and cannot find the heater core....i see what looks like the blower motor and evaporator for the a/c but do not see the heater core..anything helps greatly appreciated

Response From Timthecarguy719 Top Rated Answer

Can you look under the hood and see two hoses going into the firewall?
Behind those hoses on the inside of the car is your heater core.

Response From re-tired

You can say that again , You can say that again

Response From re-tired

Look for the pipes that the the heater hoses hook up to , thats where the heater will be . The core itself will be in the case.
