I've found two common leak areas in these cars if it has the 2.2 engine. 1. The intake gasket leaks out the rear driver side and 2. The head gasket is most likely the culprit on a car of that age. Hope this helps you. Thanks Dan

Changed water pump took out thermostat still overheating

How about more info.
The water pump is almost NEVER the issue unless it.
1) Leaks and leads to loss of coolant
2) The impeller has broken off
3) Someone has installed the wrong pump.

When does it happen,how quickly,is the radiator fan working,are the radiator external surfaces clean and is airflow unobstructed. Is the coolant a proper 50/50 mix. When starting with a cold engine and the radiator cap off are there bubbles in coolant. Did this happen suddenly or over time.

1997 cavalier 2.2 auto, coolant leaking a steady stream, it's running to the left of the main hose that goes into the engine on the top. Is there a gasket on the block other than the head gasket??

Are you referring to the top radiator hose that goes into the thermostat housing? If so then yes you have an o-ring seal on the bottom of the thermostat housing.

Few days ago cavalier decided to empty coolant out of its tank and overheat. we since then took compressor off serpentine belt changed thermostat checked oil for water flushed system checked fan heater...

Water pump. The impeller can come loose from the shaft and not circulate enough coolant. These can throw you off, because when you remove the pump the impeller will be tight against the shaft. It is when they warm up they begin to slip. If the heater core is not leaking don't bypass it.

No heat in 1997 cavalier

Most common cause is lack of coolant. Check your coolant level in both the overflow tank and the radiator itself. IMPORTANT: NEVER OPEN A RADIATOR CAP WHEN THE CAR IS STILL WARM! The radiator cap is under pressure and opening while the car is warm can lead to getting sprayed with hot coolant. If the coolant levels are fine, the next likely problem is a bad thermostat.

When adding coolant, it is important that you use GM Goodwrench DEX-COOL® (orange colored, silicate free) coolant meeting GM specifications. On these vehicles, if silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner; at 30,000 miles or 24 months.
  1. Disconnect the negative battery cable.
  2. Properly drain and recover the coolant until the level is below the thermostat.
  3. Unfasten the coolant outlet-to-inlet manifold attaching bolt and nut, then remove the outlet.
  4. Remove the thermostat. Clean the inlet manifold and outlet mating surfaces.

To install:
  1. Install a new O-ring onto the thermostat
  2. Place the thermostat in the inlet manifold.
  3. Attach the coolant outlet to the inlet manifold, using the bolt and nut. Tighten to 89 inch lbs. (10 Nm).
  4. Refill the engine cooling system.
  5. Connect the negative battery cable, then start the engine and check for coolant leaks.

Hope this helped (remember comment and rated this).

Coolant leak

i think you got a head gasket leak,,,if its buring coolant the only thing that will burn it is a leaking head gasket,,its probably leaking into the cylinder and burning it and leaking externally where you see coolant on the tranny,,,replace the head gasket,,,

My cavalier is over heating

1. Check coolant level to make sure that is right.
2. Check thermostat to make sure the one in the car now is not stuck shut.
3. See if antifreese is leaking from the water pump which is a sign that it is failing?
4. Make sure radiator cap seals correctly on radiator.

I have a 1997 Chevy Cavalier 2.2 Engine. After changing my IAC Valve, TPS, Thermostat, my coolant light still stays on. Car doesn't overheat.

If the coolant level is o/k check level indicator sensor which should be on the rad. It is a one wire sensor. Hope this helps. Moe
