hey guys so i need your help and knowledge on this one
was driving to the fiances house and about 5 min in without sound or warning the temp gauge started to rise relatively quick , and sure enough hit the red and the temp light came on so i pulled over and let it cool down. upon inspection i FOUND THE FOLLOWING
1) NO coolant leaking onto ground, so no hoses, clamps, reservoir fell apart and broke off.
2) The heat is now obsolete nothing at all , just blows regular cool air, AC works good just no hot air anymore? (heater core not getting flow, bad pump???)
3) inlet to the heater core is extremely hot as well as all the lines connected to the inlet hose, the outlet of the heater core i can grab by hand and isn't very hot at all (blockage in the heater core?? and the reservoir tank almost overflowed, it started to leak out of the bottom hose i believe do to back pressure from the heater core hence it overflowing and having extremely hot hoses)
4) UPDATE upon starting car and watching coolant reservoir i found there is no fluid return when motor is cold and warm, i read even on idle there should be coolant return before T stat opens up, i gassed it a few times to 3k rpm and no fluid came out ??? BAD WATER PUMP???
5) I'm just confused though as how my coolant reservoir almost overflowed, were talking 1" away from the threaded cap just inline with the sensor on a 45 angle, like if the return line isn't returning fluid how is this volume changing, reverse flow?? i understand everything else just dont get how i have fluid levels rising if i dont got no return fluids
if it is the pump im going to change it myself simply enough, or heater core i can back flush even
