99 olds aurora overheating and no heat

[diggerdarin]

I just dont understand y there is no heat. Core is not restricted and both hoses coming out of core get hot. Engine will not cool down temp continuous to rise. Any help?

Problem with water pump or thermostat or head gasket issue. Does it the car cools down if you hold RPMS at 2k?

[diggerdarin]

Have not tried that. Wp is new so is thermostat. Could heater core b bad?

[diggerdarin]

Will try that here shortly

[Paulaurora]

It is possible for heater core be bad.

[diggerdarin]

Tried keeping it at 2000 rpm and no luck still heats up

[Paulaurora]

Than something is blocked or air in system or heater core. I would test for head gasket issue as well

[tigger]

If both heater hoses are warm, the heater core has to be warm. Is the air coming out of the vents cold or is there no air coming out at all? It could be a blend door or blower motor issue.

I think your overheating is a separate issue. Agree with Paul, head gasket(s). Test your coolant for exhaust gases.

tigger Might be blend door but when my moms had head gasket issue had exactly same symptoms no heat and overheating. so ye best to check head gasket first before replacing parts

Thanks Paul!

I had a "99 Aurora that had a broken water pump belt. It's located to the right of the front of the engine. It runs off the camshaft. It's a bit tricky to replace the belt, but I was able to do it myself. A few year prior, I had a leaky water pump which I also replaced myself but failed to replace the drive belt at that time. If your engine overheats, CHECK THE WATER PUMP BELT!
