Bought car and the heat sucks so replaced blend doors and a new heater core just because i was in the dash that far .

Now have heat but luke warm and some temp issues so replaced thermostat now having same issue with luke warm heat untill i rev up to 2 grand then i get really hot heat let of gas and back to luke warm .

So i turned on a/c and same thing cold at idle then rev to 2 grand and super cold air .

So now thinking water pump ??

Car does not overheat never has i also replaced temp sensor. 

 

Water pump does not leak .

Notsure what is the problem is has to be water pump or a huge as air pocket any help? Thanks michael

Hi,

Have you tried squeezing the top hose with your hand?

Try it with the engine off and it will be squidgy. Idle the engine and you should feel more resistance than before.

More resistance and the pump is pumping - if its the same, investigate the water pump.

 

If still in doubt undo one of the coolant pipes to the throttle body and try briefly with the engine on?

If coolant is pumping, it should pump out...
