I'm hoping someone can help I had some maintenance done and since then I've had heating problems.
I had a timing belt/pump replacement about six weeks ago, and didn't drive the car very far after that for a few weeks, when I did take a longer drive the heat was iffy but it was cold out, but then the overflow started puking.
I put a known good thermostat I replaced when the plastic housing cracked and bled the system. Heat came back, engine warmed up fine (180-190), it puked again on the test drive after overheating. I took it back to the shop because I suspected the water pump.
They power flushed it and said it was good. It's a place about 40 miles away that I used to have good luck with, but on the way back about half way the heat started varying again and continued the whole way home.
I get little to no heat at low RPM, from idle to abut 1,500 it's pretty cold, but as soon as I start out and get the RPMs up the heat comes back, but not hot like it used to be. After warming up over 180 on the way home and holding for a while when the heat stopped working properly it would stay at 160-175. I have a scangauge hooked up.
Even revving in the driveway heat is tied to RPM. I put cardboard down in front of the radiator and it didn't overheat again but it didn't quite hit 180 and heat output stayed the same. When not lugging up hills it holds at 165 pretty well now.
My thermostat hose is lukewarm and my head hose is very hot, is that the correct flow direction? It seems backward to me but most of my experience is on GM and AMC/Jeep. Thanks.
