engine overheating, water doesn't flow.
I have changed the water pump and the thermostat. there are no leaks of water anywhere. The top radiator hose gets hot but the lower hose stays cold. Water does flow through the radiator.Another thing, on a front wheel drive 2.2 ltr. does the thermostat go in the port near the belts or does it go in the port near the back by the air filter? because at the moment it is in the port near the belts. Is this why there is no water flow?
Is dit een goede vraag?

ivan - For future reference you posted a Question in the place where only Answers belong. Please use the add comment link to the appropriate Answer, Question or create your own original Question. FWIW I think you have an air vapor lock. Have you read head replacement instructions for this car? Where did you find them? look specifically at '''Re-Assembly and though the year is different yours should be similar. Note the last step: Allowing the engine to idle for 1/2 hour with the radiator cap off can help remove air pockets.

Hi williamjelliot,
Just wondering if the gauge coolant temperature sensor unit is OK or whether it may be the ECU coolant temperature sensor unit that is the problem.
If the gauge is reading high then try disconnecting the lead at the sensor (should be just one wire) and test using an Ohmmeter. Not sure what the resistance reading should be but with most sender units it is a high resistance value when cold and a low when hot.
Where is the temperature gauge sitting if you just turn on the ignition, without starting the engine, on a cold engine?
If you can determine the brand of the gauge sensor unit the specifications for it should be able to be found online.
If it tests OK then try the ECU coolant sensor, especially if the fan does not come on (make sure A/C is off) There are videos online how to do this. Do not confuse it with the gauge coolant temperature sensor. The ECU sensor usually has 2 wires connected to it and the gauge sensor only 1.
The ECU sensor "tells" the ECU to switch on the fan.
Be safety aware and ensure that the engine is switched OFF and that the ignition key is in your pocket when working on the engine, i.e. if you have to remove the ECU sensor to test it or even testing the gauge sensor in situ.
