I agree with you that this car has longevity. I own a mazda 626 LX V4 1999. So far I have only hit 100,000. I am glad to learn that it can take you upto 300,000 miles.

#2036 of 2044 626 Fan problems by gw53

Sep 03, 2011 (9:26 am)

My 2002 626 is overheating beacuse of the fan. The water pump, fan, radiator, temperature sending unit and thermostat are all brand new. Problem is that the fan is not running when it should. It stays on for about 20 minutes and then something shuts it off. The A/C fan runs when I turn the A/C on. It's the other fan, though thatis the problem. The overheating occurs when I've driven a while and get stuckin trafiic. I turn on the heater and that drops the temperature. Could it be the fan relay? I replaced the sending unit and it is still happening. Any thoughts or suggestions would be greratly appreciated.

Try to change Coolant Temperature Sensor.To prevent overheating you can also disconnect connector from Coolant Temperature Sensor and fans will work constantly but A/C will not work.

Thanks for responding Alex. I had already replaced my coolant temperature sending unit. That wasn't it. I finally took the car in.
 
What they found was the coolant system had to be bled. The shop told me the car had to warm up at 2500 rpm, then be cooloed down completely. Then they removed the top hose from the radiator and filled the system. That was 8 days ago. Since then, it's been running cool again, no overheating.
 
I appreciate your response.

Hi All,
 
i am posting this here seeking your advice. i have a 99 626 LX V6 with 97k miles. a month ago, the temp gauge in the car was going to max and the car would stop. took it to a local repair shop and they noticed water pump leak and replaced it. repair guy said he is seeing a white smoke coming out of the car and suggested i check for coolant very often. after driving for 25 miles, car stopped again and i filled it with coolant and it was gone in no time. Now the repair guy is telling that it is a head gasket issue and would cost me 1500 repair it. i am not sure if its worth to repair it at this mileage or not. I dont want to start the repairs and get surprised with other issues. what else can go wrong.
 
So far, i did CV boot, spark plugs and spent around 2400 since 2008 on this. need your advice on what other things to be checked before i get into this repair.
 
thanks in advance.

I have a '99 626; V6 automatic with 261,500 miles on it. Transmission seems to be slipping a bit lately. Can the filter and fluid be changed on the V6 models. I'm planning to take it to my mechanic for oil change and to be checked out.
 
Just looking for pertinent information. The engine is still 'terribly strong' so a little money on the tranny might be in order to avoid buying another.
 
Thanks,
SixS

Sounds to me like the head gasket blew when the engine overheated. 97K is nothing for that car as mine has 261K and another on here has 300K so it's really toss up. I can't speak of other issues as mine hasn't had any until now. I'm waiting reply regarding some tranny slippage that seems to be happening now.

I change oil religiously every 3k miles, including the oil filter. I use Castrol GTX 10W30 regular oil (no synthetics). I use Mazda filters as they are reasonably priced from my local dealer (about $ 5/piece with my discount). The car has had 111 oil changes to date. There is no sign of any sludge in my engine after nearly 334,000 miles. I change spark plugs every 60 k miles, use only the OEM platinum Denso plugs. I get them cheaper from sparkplugs.com. I change plug wires at least every 100k miles. Use only OEM NGK wires. They are available from rockauto.com for about $ 75/set. I change the brake and clutch fluid every 2 years. I change the coolant every 60k miles or so. I use Mazda brand orange coolant. I replace the drive belts and tensioner pulley bearings about every 80k miles. I change the timing belt, water pump, and timing belt idler pulleys every 100k miles. I also replace the valve cover gaskets about every 100k miles, usually when I do the timing belt. I am on the third set of brake pads now, getting ready to replace them.
 
There is one annoying issue with this engine - the EGR flow passages in the intake manifold clog with carbon about every 100k miles and must be cleaned. Otherwise you will get an engine check light with the "EGR flow low" code. The EGR valve itself is bulletproof, as it electrically operated (not vacuum) and it is cooled by engine coolant.
