Check your heater tap in the engine bay ...they usually ran off a vacuum hose.
If the system was not bled properly..ie by filling the radiator WHILE the bleed screw is open you will get an airlock.
the bleed screw is usually on or near the thermostat housing.
The water level must be higher than the top on the engine (I use a piece of PVC pipe in the radiator filler to do this.)

Also make sure the thermostat is not stuck in the closed position.

Fans are not turning on, on my 04 chevy impala ls


check the plug that connects to the fan motor for bad or corroded contacts. then you can run separate jumper wires from the battery to the rad cooling fan motor if the fan doesn`t run then replace the fan motor. if it runs then it could be the coolant fan relay, coolant fan sensor in the motor, PCM, or a wiring problem of some sort but fan motors are common.

How to change the water pump on 2000saturnsl2


Here is that info.
Have a full set of Torx sockets inaddition to the normal ones.

Support the engine.
Remove the air filter box.
Remove the front engine mount.
Pick an order here for the belt and pullies.

What ever will work for you. This is because the serpentine belt will llikely not stop the pullies from spinning. A flat pry bar through two of the bolts on the water and PS pullies while you loosen the third works better. Be careful as the bolt heads round easily.

Remove the water pump pulley.
Remove the power steering pulley.
Remove the serpentine belt.
Remove the lower crank pulley. Outer bolts not the center one
Remove the belt tensioner.
Remove the timing belt covers.
Put a coolant catch pan under the front of the engine.
Remove the water pump.
Clean the sealing surfaces. install the new pump anbd reinsatll the removed parts.
Fill the cooling system and hope that the heater core did not drain. The heater core tends to air lock if it is drained of coolant. This is why the coolant is best drained by removing the water pump and not draining the rad and the entire system.
Run the engine until you have good heat in the car with out having to rev the engine.
Check and top the coolant level as needed

The heater only blows cold air,the radiator is full,thermastat is working and the engine temp is within normal ranges.


I've had this problem. 2000 GMC uses a closed coolant system. Meaning takes and returns coolant from and to the Reserve Bottle and has little air in the engine and heater systems.
If everything appears ok but no heat. "Air Lock" is the most likely cause. (With interior heater set to full heat) Solution; 1. Make sure water pump works. 2. Drain about 1/2 engine coolant into container. 3 Remove both heater hoses from engine side and flush heater core in both directs through heater hoses with garden hose. 4. Reattach heater hoses in correct locations. 4. Refill engine with coolant. 5 Start engine and run for 2 min., use caution when topping up coolant.
6. Most 2000 GMC have twist off caps with plugs located mid way on heater hoses. with engine cold, start engine these caps may be loosened to allow trapped air to escape. Do not attempt with engine hot due to hot coolant injuries. This may take more than one attempt to remove all air from heat system. 7. Lastly most 2000 GMC water pumps have a bleeder plug,( 3/8" square driver plug) located on the water pump. With egine cold this plug should be removed to remove any air. Reinstall plug with thread sealant.
Hope this helps cheers

On 2000 4runner, i changed the water pumr ,thermastat, and timeingbelt the problem i am having is heat . When i pull both heatercore hoses i do not get any flow of coolant untill i rev the motor ,i tried...


There is an air pocket trapped in the cooling system. I have found that if I splice a flushing tee, found at the auto parts store, into the upper heater hose, and fill the cooling system, it usually bleeds the air out of the system.Is the t-stat installed properly?

1994 Toyota truck over heat we change water pump , head job, radiator thermostat


did you guys flush the coolant system and make sure there wasnt any corosine in the radiator, plus on some of those models you have to make sure that all of the air bubbles are out of the system or it get almost like vapor locked and the water wont flow throught the system,, also check the heater core try by passing it and running the motor you might have a plugged heater core also ,,,

I took my toyota camry 1992 v6 to change coolant and now it is over heating. I took it to the mechanic and he said it is not the water pump. After I change the coolant, the heat did not want to come out....


It sounds to me that your car is likely air locked. Your Camry may have an air bleed on it, some of the newer cars do. Either way what you can try is to loosen the radiator cap to the safety position (where you have to push down to remove it) and run the car normally for a day or two making sure you keep the radiator and the overflow bucket topped up. I know it's getting warm but keep the heater turned on so that water will flow through the whole system and flush out the air. After a couple of days top the rad up again and close the cap tight. You should be good . It is possible that your thermostat may need changing too, but I'd try this first.

Water pump problem?


You need to make sure you don’t have an air lock. Find the bleeder valve for the coolant system and release the air. If you can’t find the bleeder, find the highest hose for the coolant system and make sure coolant is flowing through it.
