Re: Replacing Heater Core
I believe there are five nuts on the firewall, 1/2 inch. Starting near the battery, with the last right behind the valve cover. One change i did, the box is sealed with black goop similar to the stuff used to seal windshields in, i scraped the old goop off and used the foam weather stripping from Home Depot, 1/4 inch stuff. Makes it alot easier the if there is ever a next time. Pretty easy job though. Definitely do the blower upgrade!
Actually, I have a wrangler tub on mine, so i don't know if the process is the same on a CJ-7. Anyone?
