I've been testing my new aluminum radiator and posted in other discussions that my radiator fan switch was kicking-in too late. Found that I had air in the system which caused the problem and surprised me since I thought I had already removed all the air.
NOW I'm finding that after I remove the air from my system, more air is introduced after driving it. If I burp the system and let it run, everything is fine. But when I drive it again I find there is air in it. I have no coolant leaks and the coolant reservoir level doesn't seem to be dropping (although it is hard to tell with a stainless tank).
The new radiator is so efficient that everything works fine when the vehicle is moving -- even on a hot day with air in the system. I only notice a problem in stop-and-go conditions where the system is working harder.
I realized that I did not have a washer installed on the radiator valve. There wasn't one on the OEM unit either -- must have disintegrated. I've since added a fibre washer to the system but it's still sucking air
Any recommendations on how to diagnose how air is getting into my cooling system???
