Whats up passat world, i need help with a coolant issue. So basically Im working on a 01 passat 1.8t aug which had a broken timing belt and bent valves so the head came off and all of its back together running great. I dont know if the heat worked fine before this but I cant seem to get it to work now and i dunno if thats really all my problems right now or not. I may of but a coolant hose in the wrong place or something but i dont think so.
So starting from the begaining I ran the car for about a hour without bleeding or anything but i did have the cap off and I could never get any heat. The next day I locataed the bleeder hole and lifted the coolant tank and removed the cap. I ran it like this for like 2 hours sometimes holding the throttle for several minutes (could c the turbo glowing a little) and bled it but still to no avail and most of the time even with the cap on it, it wouldnt build pressure. I also found a small leak, fixed it and pressure tested it at 15pounds which seemed to hold fine for ten minutes or so, when i had the pressure tester on it, it seemed all lines had pressure. So i got a new cap today and tryed it again, this time it seemed a lil easier to pressurize but it required me holding the throttle for several minutes. Bled it again but still no heat. So i hooked a scanner up to it and noticed one coolant temp sensor read 199 and the other read 145, I also noticed the long term fuel trim (i had the battery disconnected when changing the head so these r fresh readings...i guess) was add 16.4% so im assuming the ecu is adding fuel cause its been running cold. Where r the temp sensors located? i saw one in the back of the head but I dont c the other
Im at a lost, the only thing i can think of was the thermostat, i hoooked a hose up wrong, or the heat (im assuming its operated by a bleed door only cause i didnt c a valve) never worked to begain with. I guess il but a new thermostat in it regardless but now i dont think its the problem. Maybe the waterpump i put on was reverse flow or something i dunno? do other passat pumps flow different but bolt up? Helpp!!!!!! and sorry i double posted
