Gonna need a heater core...

[Paul Workman]

Are there any heater cores that cross-reference to a 90 ZR-1? I'm assuming by the fogged windshield (at times) and the carpet soaked on the passenger's side that my heater core is shot. It could be a hose or fitting, I suppose, but that wouldn't be consistent with my usual luck!:rolleyes:

Any suggestions where to round up a core??? Mucho appreciation.

I believe all heater cores L98,LT1,LT4, and LT5 are the same

try Rock Auto.

as for the heater core replacement, Good luck

Paul, now I may not be able to come there and help, but can answer questions when you are ready to pull it

Considering we rarely use our cars in the winter or if you just like having a car where "everything works" I think I would consider just bypassing the heater core and forgeting about the hassle of replacing it.

:censored: Paul nasty job. I see them on Ebay all the time. No difference in the Heater core than in any other C4. Man I dont envy you that job. :jawdrop: Rockauto as stated is also a good option. Id Bypass it until the weather is the most favorable for you to work on it. (early Fall?)

If I could offer some advise. Take off the roof panel and remove the passenger seat. Your back will owe me a beer. And it helps while working upsidedown. D

When I bought my car someone bypassed the heater core. I never found out why nothing wrong with heater core. Down side of bypassing is climate control will not work as it blends hot a cold airflow. Adjusting the controls was not effective and could never get temp close to right.

It is the same as the L98 car. 52479882, it's still available from GM.

How do you temporarily bypass the heater core? I have had my ZR-1 for 8 years and never used my heater or defrost. I would like to bypass it before it starts to leak, and someday if I need a heater, or sell the car reconnect it. Thanks

I'm looking forward to tearing the dash apart about like "going to the woodshed".:cry: But! I do driver 'er a little in the winter on sunny, dry days and a defroster and warm toes are nice. SO...I recon I'll bite the bullet and change the SOB and be done with it. But, I may bypass it until cooler weather arrives - hadn't considered that, Hans...Good suggestion.

Other than lots of distilled water and a wet/dry shop vac, any suggestions on getting the antifreeze out of the carpet???:???:

TIA,

Paul, what color carpet is in your car? Also the dash is not TOO BAD to remove, but it depends on what the book says too. I thinkt he dash pad has to come out, but again, I may not be able to drive downa nd help,m but I can guide you through on some things
