    The thermostat would be the first thing to replace for overheating, have you done this?

If the car heats up real bad and then the temp drops suddenly, the problem is the thermostat. However, it could also be a plugged radiator or a lazy fan. If you have a mechanical fan with a thermal clutch, you need to see if it is working. Electrical fans are easy to diagnose because they eventually come on or they don't.

I have a Mazda 323, I've had the timing belt, water pump and thermostat replaced. After driving for about 15mins the temperature gauge starts to rise to the 3/4 mark. While at idle it's drops down, only...


I suspect that there is an air lock in the cooling system. Check that the radiator is full at the cap. Take it to an accredited radiator specialist to have any air purged from the system

If air conditioner system not working cause 1999 Mazda 626 2.0L to overheat


No this wont cause an overheat problem. Check the coolant level , check to see if the fans come on after it heats up. when the car is warming up you can check the thermostat, by touching the top radiator hose, after a few minutes the hose should get hot, this indicates that the thermostat opened up and is working. If it doesn't replace the thermostat. If it doesn't over heat until you start driving , then suspect the water pump. The impellers can slip on the shaft and not have enough flow to keep it cool.

My mazda tribute is overheating alot


Hi and welcome to FixYa!

There are few things that can cause the vehicle to heat. Please check the following to resolve the issue:

- A faulty water pump can cause the car to overheat. If the water pump is faulty the coolant will not circulate properly on the engine which can result to overheating. You will need to have it replaced if that's the case.

- A worn out or damaged radiator hose. Just a small hole on the hose can cause the vehicle to overheat so have it replaced.

- A weak radiator blower motor. If the blower motor is weak it tends not to cool down the engine so have the blower motor replaced.

These are the few things that can cause the car to overheat so please have the following be checked.

Hope this helps and thank you for using FixYa! Have a good one!

1998 Mazda 323 Protege - constantly overheating, even after fairly short runs (10 minutes). Coolant overflow bottle turns from green to dark grey each trip and almost "explodes".


Possible cause ;
1. Water pump
2. Thermostat
3. Bad head gasket.
4. Low coolant level.
Try to replace thermostat first , this way you illuminate thermostat and coolant level , you'll have to ad coolant after replacement and purge system.

Engine overheating


All i can think of is the thermostat is not opening. or you may have a clog somewhere preventing the flow. Check the T-stat and hoses and radiator ( for clogs) Good luck
