Engine overheating - water pump Good, Thermostate good, The water blows out of the reservoir.


How do you know the water pump and thermostat are good ?
Have they been replaced ? Did you check the fan clutch ? Restriction in the air flow thru the radiator ?
If they are new and installed correctly, and the cooling system is full and has no air pockets, and the engine overheats within a few minutes of driving, I would expect to find a blown head gasket.

My 98 chevy malibu is running a little hot. the heads are not cracked.changed the anti freeze.change the thermostate. what could be the problem


If your engine is running fine with no miss in it possibilities could be radiator fan or water pump if the radiator fan is working fine it could be the water pump. I have seen a water pump after removing it where the fins on the pump were completely worn out causing the overheating.Let me know how this turns out for you thanks.

The thermostat is located in the water pump on mostn never Chevy trucks. If you pull the upper fan shroud, you should see the thermostat housing. Remove the radiator hose, then the 2 bolts for the housing. Replace the thermostat, and gasket together.

Water pump replacement - how involved is replacing the water pump


The waterpump on a chevy suburban can be removed once you remove the radiator fan.
  1. Drain the coolant from the system.
  2. Here is a way to remove the fan clutch withouy a fan clutch tool. The trick is to leave the belt on and tight.
  3. Take a 1 7/16 inch wrench and put it behind the fan onto the big shaft nut attaching the fan to the water pump. P
  4. ut it straight up and crack it counterclockwise with a hammer.
  5. This should loosen the nut.
  6. After that just spin the fan off and the rest is easy.
  7. Make sure you clean the old seal off of the engine. It is small and easy to miss.
  8. remove the serpentine belt.
  9. remove the hoses connecting to the water pump
  10. remove 4 bolts holding the water pump onto the block
  11. clean the block of any old gasket
  12. fit the new waterpump and new gasket.
  13. connect the hoses to the pump.
  14. refit the serpentine belt
  15. refit the fan
  16. refit the rad and cowling
  17. fill it up with coolant.
  18. Run the engine and check for leaks.

OVERHEATING EVERY NOW AND THEN WITH COOLANT COMING OUT OF OVERFLOW BOTTLE


Inspect the following: 1.(typical on these models) Possible cooling system caps leak allowing coolant to escape and air into the system. Replace if leaking (there are 2 caps- one cap on the top LH side of the engine and one on the radiator) 2. Radiator fan- This fan on the V-6s are hydraulic driven via powersteering pump, inspect for fluid leaks and proper fluid levels. (To test fan speed, unplug the switch located on the powersteering pump and rev motor to 2000 rpm fan should pick up speed)have it checked if problematic. 3. Replace the thermostat if this hasn't been done in the last 30,000miles, possible binding or stuck (located on the LH side of the engine, under the alternator and at the back end of the coolant feeder pipe). If these all check out fine, inspect or replace the water pump. To replace the pump it requires timing belt removal and or replacement. Hopefully this helps
