So my gf drives a 2000 venture, one day she drove 45 mins one way, in spent maybe 10-15 mins with engine off when she got there, and on the way home the van started to overheat, she pulled over before it got near redline, notice all the coolant was stuck in the resivor, we had it looked at, they told us it was a bad thermostat, and it needed a coolant flush due to it look bad.
We paid for the new thermostat and a coolant flush and it needed a fresh tune up due to system light said back spark on cylinder 2.
after doing the flush etc next day, it was still overheating, we assume he didn't bleed it, well i guess he did, when i pull the radiator cap off and start the car
you can see the radiator bubbling and boiling up
would this be a bad water pump? bad head gasket? there is no coolant leak anywhere, no creamy stuff in the dipstick.
even after doing a new spark plugs/wires/etc, van still running like shit and overheating still.
