Still chasing down leaks. While I was working on the trans leaks, taking some of your suggestions, etc., I got up off of the ground and looked back at the front of the truck....Trans fluid dripping from the pass side frame horn. What?
Long story short, it is a completely separate leak from the one at the trans. The trans cooler circuit in the new Champion aluminum radiator has a bad seam. It was murder to find it...But that's where that one is.
So, instead of finger pointing with the mfg., and instead of pulling the radiator, overflow can, wiring for the pass side of the engine, electric fans, dumping coolant all over (the part that didn't get into the 5 gal container...
There always is a ton of it, no?), I decided to make sure of the source of the leak, bypass the on-board radiator trans cooler, and add a remote cooler.
For now, part of the testing process was to run sans-trans cooler, up to pressure and up to operating temperature, by simply connecting the two trans cooler hoses together.
Done. No leaks. The rest of the cooling system, including heater circuit, engine cooling, is tight, and incredibly efficient. Truck stays nice and cool at an idle...The electric fans don't even turn on until placed on the lowest setting.
I don't trust temp gauges, but the one in the dash doesn't read over 1/2 hot after a drive and a long idle.
Okay, now for a trans cooler. Any suggestions?
Ahhhh...I'll do it next week. I'm tired. And I have a life other than this truck!!!!
