Heater problem 1999 Mazda 626

Have checked the coolant. I have changed the thermostate. The radiator cap seems to be working properly. Both of the hoses exiting the fire wall are hot. I have seperated the AC coil duct enough to look up in to see if any thing is blocking the air flow. All looked clear from what I could see. The heater still blows cool air. I have read about a blend door that could be affecting the tempature. Any help would be fantastic

Under the dash board on the passenger side is where the heater core is located anything associated with the blend doorwould also be located there as well.

Changed radiator thermostate and cap and took heater core no coolant going through heater core


Did you open the actuator in the heating system so that coolant goes thru ? You may want to start your vehicle and take it for a drive with the heaters on high. This will help you get the air out of the system.

Take a gallon of antifreeze with you and keep an eye on the temperature gauge. also make sure that you hear the fans run, which will let you know that your fans and sensor are working properly.

1996 mazda 626 overheats after shur off and sometimes driving. no smoke


sounds like a restricted radiator.. the thermostat has 2 x jobs to maintain the temperature and to restrict the flow-so by removing the thermostat you actually went backwards- meaning the coolant will flow to fast thru the radiator and will not have time to be cooled down prior to returning to the engine block. since your heater helps to cool it down my guess(educated) would be a restricted radiator..

Physically look in the radiator under the cap for coolant level, and check the valve in the cap for sticking. If air is present in the radiator it can't get out, and more coolant can't get in,(from the overflow). Either clean the cap or replace it and check that it is the CORRECT cap.
Radiator fins dirty, clean with a strong stream of water, not high pressure water.
Radiator clogged, have it boiled out, or replace.
Thermostat stuck open or shut, replace it.
Water pump worn out, can no longer move enough coolant, replace it.
Fan shroud broken or missing....
Electric Fan(s) not working, Check the fan, relay, fuse and engine temperature sensor's.
Belt driven fan, belt slipping, fan clutch is bad, fan blades have flattened out.

Air dam under front bumper is gone, loose, or broken. It actually has a purpose other than scraping on the driveway or curbs. It forces air up into and thru the condenser and radiator. If it

Overheating


The first thing to check would be the coolant level, do this when engine is cool, if its full of coolant then my next step would be to make sure the fans are turning on, the most common thing would be a thermostant, you may want to start there and then see if it still overheats, if it does then take alook at the electric fans, if they are not turning on you may have a bad sensor that controls the fans to turn on at a certain temp,that part would be the coolant temp sensor, but start with the thermostant and checking the coolant level.

1994 Mazda 626 ES overheating


New water pump.... new timing belt.... new radiator cap... but the idiot mechanic has not done the obvious.

1. Change the coolant thermostat located under the hose fitting on the manifold where the top radiator hose connects to the engine.

2. Check the radiator fan switch for proper operation. When in doubt change it out. A $30.00 switch isn't worth risking a complete engine overhall.

3. Do a compression check on the engine to make sure all cylinders have close to the same amount of comression. Overheating can cause head gaskets to weaken and fail. Performing the compression check would verify that both the cylinder head, valves and head gasket are still in good working order.

4. (Applicable only to cars with a belt driven fan) Does the fan have a fan clutch? I did not look it up yet. If it does then the fan clutch can also be a problem if it is not turning the fan when the engine is hot.

For cars with an electric fan the switch in step 2 applies as does checking the fan for proper operation.

5. Fire your mechanic! If there is one thing I hate it is a mechanic that only does half the job vs checking out all possible causes! Your car should have never left the shop in a state that it could over heat AGAIN. Time to have a chat with she service manager and the service managers' boss! They owe you some free labor!

Thanks for using FixYa.

have you checked your
thermostat, most of the time it is that make sure that you check that your water pump is also working if after you have checked all this you must check and flush your whole radiator system.

1992 mazda mx3 is overheating. checked thermostat seems to be working. Noticed that the heater started acting up a few days before it overheated......Heater works randomly, seems like you start the car...


Check your coolant. If the coolant is low, you won't get heat in the cabin. Make sure that the fan is turning on as well. Check coolant sensors also. Good luck!
