Need help on this!
The truck is on a RaceME Ultra 200hp tune.
lets start a couple months back the internal gasket on the t-stat ate itself away so the truck wouldn’t get to temp in timing of the ecu wanted so it kept throwing a code.
Replaced the t stat and new radiator with a Murray and cap that came with the radiator. Bled the truck a bunch when refilling, always using the vent tube going to middle of the block like should to release air. Bust it off every time after getting truck to temp to release air and once fluid comes cap off.
well a week or two ago I noticed something on my fender which was coolant that blew out of the overflow tank.. tanks was full of coolant.
this is I’m talking more then 20k miles on it since last coolant swap.
figured if I had a air trap issue it would have done it immediately..
well I drain the overflow and cap off the rad.
leaving the vent tube bolt off like always till it poured out fluid. Did this 3 times getting it everywhere cause at this point I was tired of trying to keep things clean as I kept doing it.
week goes past since I first seen it blow out of the overflow. The water pump starts dumping coolant out of the peep hole. Not a trickle like steady stream. Drove the truck 30 minutes to the shop never went over 210 degrees with it puking coolant.
swapped the pump out with a factory pump Friday may 6th. It’s now may 11th only put 150 miles on the truck and the overflow is full and about to blow out but luckily I’m already parked for the day.
so here’s the thing.
truck never goes over 205 on temp.
usually around 192-197
but I can open the rad cap at any time. No matter if the truck is to temp or not. Cap side top of rad is cool to touch and the t stat side of rad is hot.
do I have a gasket splitting pushing exhaust gasses into the overflow tank???
need help asap as I don’t want to be stuck on the side of the road but I do need to use the truck.
