The temp sensor is usually on the thermostat neck located at the end of the top radiator hose. while car is running disconnect this sensor and fan should come on with in a few seconds this will indicate that fan is good and sensor is bad.simply replace it and your problem will be solved. any further issues call on me

I have a 1994 Mazda 626 ES V6....Lots of 'steam' coming from behind engine. Smells of coolant. Assuming the need to R

You have a steamed-up windshield on the inside? Yes,the heater core has a leak.Passenger side foot well full of coolant?

If steam is inside the engine compartment,you just have a blown heater hose WAY back there.

94 mazda 626 cv shaft removal

Stick a large screwdriver or prybar between the CV housing and the transmission case, and pop it out. There is a little circlip in a groove near the end of the shaft inside the transaxle. It is there to seat the shaft and prevent it from slipping out during driving.

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 626 2002 is overheating we have replaced the resevoir and the caps and its still doing it its fine when driving than when you come to an idle it starts to heat up again and than will go back down...

it sounds like the radiator fans are not coming on. Check the fuses and relays for the fans. there is a temperature switch to control when the fan(s) comes on. If you have AC then the fans should come on when you turn on the AC.

I have 2001 mazda 626 and its overheating. we have checked fluids nothing is leaking or coming out levels are good. we have replaced the thermastat and its still doing it. where should i look next? ill...

when does it overheat ? wile driving at hiway speeds ? or at idle or wile driving in stop and go traffic ?

if it overheats on the hiway, supect a restricted radiator, or a blown head gasket or cracked cylinder head.

if it only over heats at idle or in stop and go traffic, supect no cooling fans.

2001 Mazda 626, intermittently overheats - especially but not always when not moving

Sounds like a fan issue...

Maybe a fuse, could be the relay.

Start the car and let it run at idle while not moving... if the car over heats and the fan never kicked on, then you need to figure out why it isn't kicking on.

to check the fan you simply need tro run a direct lead to the battery..if it doesn't come on then the motor is probably burnt up, if it comes on with a direct lead, then you have another issue.. fuse, relay, or thermostat.
