What else can you check if your 1994 1700 turbo diesel Cavalier keeps overheating after took out the thermostat and put in a speed flush gaskets are good?

Here are some other things you can check if your 1994 1700 turbo diesel Cavalier keeps overheating after removing the thermostat and installing a speed flush with functional gaskets:

1. Check the radiator. Ensure the radiator is clean and free of debris, such as leaves or bugs. If the radiator is clogged, it will not be able to properly dissipate heat, causing the engine to overheat.

2. Check the radiator cap. The radiator cap helps to maintain the pressure in the cooling system. If the cap is faulty, it can allow coolant to escape, which will cause the engine to overheat.

3. Check the water pump. The water pump circulates the coolant throughout the cooling system. If the water pump is faulty, it will not be able to properly circulate the coolant, causing the engine to overheat.

4. Check the fan clutch. The fan clutch engages the fan when the engine reaches a certain temperature. If the fan clutch is faulty, it will not engage the fan, causing the engine to overheat.

5. Check the head gasket. A blown head gasket can allow coolant to leak into the cylinders, which can cause the engine to overheat. If you suspect that the head gasket is blown, you will need to have it replaced by a qualified mechanic.

If you have checked all of these things and your engine is still overheating, you should take it to a qualified mechanic for further diagnosis.
