Re: Water pump outlet to heather

Re: Water pump outlet to heather
im not sure... i have a replacement water pump and i think my casting is bad. i have little to no heat in the truck.... not a big issue when im in florida... but i froze my azz off when i went to chicago for the holidays to hang out with my kids... its pissing me off as well... i eat about 1/2 gallon every 6 months of anti freeze... i find no leaks,(die black light) holds pressure, no exhaust fumes bubbling in coolant, no signs on plugs... but every once in a while i smell steaming coolant... thinking it may be a dodgy pressure cap.
or it could be seeping into the intake somehow and leaning out the fuel mixture but still being burned... i dont know enough about my engine to know off the top of my head every coolant port inside the motor and where they may leak. i was the guy at the factory that dealt with quad 4's and the 3.4 twin dual ohd motors... and other assorted items for PMD... the return seems like it needs to be ported to the other side of the tstat for flow to actually happen...

the return from the heater core goes directly back to the tstat housing/water pump... it does not go back to the over flow pressure tank...

Re: Water pump outlet to heather
Might be interpretive, but perhaps that diagram just indicats a tee in the heater line where the pressure tank connects. I don't interpret this as meaning the heater hose goes straight to the tank.

Re: Water pump outlet to heather
That is designed for sealed radiators that use a remote surge tank (kinda like using the ps pumps that have a remote resevoir). If your radiator has a cap with a pressure rating, then your don't need that. The idea is that it keeps some extra fluid and give the fluid a place to go under. It also helps keep a full radiator since it hold extra fluid that can drain into the rad if it gets low.
Most of us have a regular capped radiator. You fill the rad, and run an overflow so it has a safe place to dump if it overheats. We would have to manually add coolant or water if the rad got low, but you also don't have to place and plumb an extra tank underhood.
