You probably never cleaned the cooling system out.

If you have not get it done by pros.

It seems something is blocking the flow. If the water pump went bad you will know. Rarely ever heard a impeller breaks off like you think. The bearings and the seal break first.

Check and see also if the heater valve is working.

As for the over heating even new thermostats fail. Reverse flush is needed or the procan measure the pressure in the radiator cooling system and edetermine if there is a engine pressure problem. Tools and experience is the key in the game of diagnosis.

Thermostat problems


your easy, that is caused by AIR Pocket in the engine block
the gauge can not read, air temps so if air is below the engine
coolant thermostat the ECT reads hot then air (cold ) repeats
you lost coolant and the number one reason for that is trusting
the silly side tank, (they fail easy)
never do that, on the next cold morning , dead cold
you take off the RAD cap. look down the neck, is it full of green
AF? id bet you its not.
the cab heater will never work with no engine heat, ever. so ......
never do the above on any hot engine.
also the thermostat might be bad and the coolant overheated
and blew out, so get a new STAT.
the flush the system, and refill with 50% AF.
or worse. lots of ways to overheat.... ask.
the side bottle only works, (called the expansion tank)
if never overheated
and the tube in side is not dropped off
and you never let it go dry, ever.

those facts and others are why we check the RAD directly cold.

Heater in 1996 Cirrus not blowing hot air. Radiator hose is cold


did you put new thermostat in the right way ? do you have a 50/50 coolant mixture in rad, 50 % water in rad is what gives you heat, aside from your thermostat, are your heat controls in the proper locations ?

Have a 2001 dakota sport 6 cyl. and have coolant dripping from bottom of water pump.found loose bolt on bottom and tightened it.drove around at first no leak,then heater blowin cold air,then shut off...


Gasket probably will not seal now, and if your going to have to remove water pump to replace it, you might as well put a new pump on as well. The reason for heater cutting in and out, is probably just due to low coolant, and air got into system. When cool, remove rad cap,start engine, and turn heater on while letting it get up to operating temperature, and top up rad as needed, until you see increased flow in rad indicating thermostat has opened and coolant is circulating. Watch for that a couple of times, then put rad cap back on, and top up return bottle to proper level as well. That should get your heat back.

Changed thermostat and added coolant but 1997


could be waterpump?
i was going to say rad fan,but if so heater would be hot.
lack of coolant will make heater core to blow cold,if engine heats up with full coolant,usually means poor or no circulation.
water pump?
run engine with full coolant,at operating temp.with rad cap off and look in rad cap hole and see if there is movement of water inside rad.
[rad fan will not come on if water is not circulating through rad water pump?]

A new heater core and thermostat was put on, but it still just blows out cold air. How do we get it to heat?


If the hoses ,rad and heater core have been flushed,check,replaced,then you are now down to a coolant flow problem.This meens either the water pump belt is slipping or the punp fins have rotted off and you need a new pump.

New heatercore but no heat flushed system out but still no heat the dash gets hot but very little heat comes out when on for awhile the fan works just blows cold air


Did you run engine from cold, with heater on when you refilled the system? Try again, rad cap off, with heater on, and let engine get up to operating temperature, make sure you have good flow through rad ,leave cap off, until rad fan comes on to cool returning coolant to rad at least twice. Give engine a little extra rev, for 5 seconds or so, every once in a while to make sure flow getting through heater core, and add coolant as necessary. See if that helps, as it may just be an airlock in system. If your cooling system has any bleed screws incorporated, crack them once in a while as well.

Vehicle needs to purge all the air form the radiator. Jeep Grand


Start vehicle when cold. remove rad cap, start engine & put heater on (not defrost) and let it run for a while & top up rad as coolant goes down, to about an inch or 2 from top of rad. If you have electric rad fans, watch temperature gauge and around normal operating temperature or slightly above, they should come on for a minute or 2 then shut off. If not electric fans, just watch in top of rad for increased flow through rad, indicating thermostat has opened & coolant is circulating. Rev engine slightly every once in a while for 5 or 10 seconds just to help increase flow etc to help assist bleeding air out faster. Watch for increased flow in rad, 2 or 3 times at least, or listen for fan to go on & off 2 or 3 times before putting rad cap back on. As your doing this, keep topping up rad if it needs it. Make sure rad cap on all the way, check coolant return bottle level & add to mark if required, and you should be good to go. One of the things people forget to do the most, is to turn heater on while doing this, and that is usually what causes a lot of airlocks in the system, so don't forget that step.

2005 yukon denali is overheating


Start it cold with rad cap off, and heater on high heat, and let it run until you see increased flow in radiator, indicating thermostat opened & engine reached operating temperature. Rev engine slightly every once in a while and hold it there for 10-20 seconds, just to help purge air better/faster. Watch rad flow again, and wait until you see increased flow 3 or 4 times. Then top up coolant in rad to an inch or 2 from top of rad, and put cap back on. Top up return bottle to appropriate level on bottle & then try it again. If it still heats up, get back to me. Does it overheat at all times? Rad fan is good i take it?
