Hi guys!
Soooo, long day today, 104 F and my garage was turned into the shop for today. I took the heater core out and checked the flap. The foam stuff is 100% fine, all present and in good nick.
Took me 1.5 hours to dis-assemble, no problems. Glad I did this so now I know that this is not the problem.
Ok, off to Autozone and bought a can of 134, checked on Pelican tech articles the needed pressure. Well, pressure was at 23 psi..... Got it up to 42 psi. Took no time at all. 37 bucks ain't too bad.
It seems cooling got a lot better! I still want to check after a days work when the car baked in the sun.
I get back later with a follow up.
Thanks for all the tips
Andy
