Did you find a solution?

Well, that explains that! Then my next question is ,why will it run for 45 mins then quit? Won't restart until couple of hrs later. Tank clean, new sock, pump working,, I'm at a loss. Great running when running

water does not flow from radiator to reserve tank by mazda626atx

Hi Guys
 
MY wifes Mazda 626lxa (1994 atx ) overheated last week in Greece. We costantly check the water level from the plastic reserve tank and it is always full, or we top it off.
 
 After car overheated she brought it to a mechanic who said we must check by opening radiator cap while cold , once a month and and see if it is really full. He said with age water does not circulate properly between actual radiator and reserve tank. He compared it to hardening of the arterys in people. He also said bubbles can flow in the line and stop the water from passing
 
  He drained all the coolant, refilled it and said keep an eye on it . Lo and behold after an aprrox 200 fairly high speed (80MPH ) mile trip in hot weather , she opened the actual radiator and it is a little low , while the reserve tank is showing completely full.
  Is there a hose that connects the reserve/ overflow tank(plastic) to the actual radiator that could be the cause.
 
  What else can cause this problem in a 15 year old car .
I am presently in the States and am trying to diagnose the problem with your help from afar.
Thanks

Something needs to be done about how poorly this car was made and the people who have been made to suffer for investing in Mazda. I will never buy from them again.

Yes, there's a pipe (usually a hose) linking the plastic reserve tank to the radiator, and it might have been blocked, though, this is rarely the case.
 
Most overheating problems in 626s arise from wiring problems with d cooling fan(s) (e.g. burnt out wires) or blocked radiator cells (usually from accumulation of sludge over time due to filling with dirty water).
 
To prevent overheating, always be sure that your cooling fans are indeed working whenever u switch on d car engine. If ur engine still overheats with d fans working, ur radiator cells may be clogged. Finally, if u've had ur radiator removed and d cells cleaned out at a mechanic's, and ur car still overheats, d source is definitely from excessive friction within d engine block. U might need to change ur oil, filter and spark plugs.
 
I,m certain by d time u've tried all these, ur car will b just o.k.

These cars are also known for the coolant tank developing a leak at the bottom. I have replaced the tank on my daughter's '99 model twice in the past 3 years. Both developed cracks on the bottom in the seam of the plastic tank. First indicator of a problem was overheating, especially when stopped at traffic lights.

i WAS GOING DOWN THE INTERSTATE AND THE MOTOR STOPPED PULLING. BY THE TIME I COASTED TO THE SIDE OF THE ROAD THE ENGINE DIED AND WOULDN'T START. I HAVE HAD FRIENDS TELL ME THAT IT'S TIMING BELT. COULD THIS BE TRUE? AND I ALSO HAVE A MAJOR OIL LEAK INSIDE THE TIMING COVER THAT I CAN'T FIGURE OUT WHERE IT'S COMING FROM.

Yes, a timing belt failing will cause the engine to die. but there are lots of other things can cause the engine to stop. Top things that come to mind are, dead battery, failed alternator, alternator belt breaking, ignition coil failing, spark plug wire to ignition coil failing, overheating, engine fuse blowing and of course running out of gas.

Once on a freeway my mazda 626 1999 model car all of sudden died, in such a way that dash board lights and all electrical functions went dead and the car comes to a complete halt. This was simply due to a dead fuse, but the mechanic charged me $600 US$ and at that time I was not sure. My car was coming from a hot environment and then into a sudden cold and was probably running for 2 days continuously, and that could have contributed to this. So do make sure that it is not the fuse.

I Own a 1998 Mazda 626 lx V6 automatic, I just purchased it 3 months ago in what I thought was great shape.. It has now began to have many different issues. First the check engine light stays on, then the RPM starts to go higher than before going up to 2500-3000 before switching. It felt like it was just delayed a few seconds more then normal. I then took it to mazda and they said the diagnostic was "PO400, EGR system flow malfuntion which may be plugged or open "was causing the engine light to stay on and that I need a new transmission to fix the gear switching issue. Now the brake light has started to come on when I stop, but the brakes are fine. Then I went to start it today and it felt like the starter was toast, (wasn't doing anything).........I tried it a few more times then it worked.....clearly alot of issues....can they all be related to the EGR valve? I really can't think about getting a transmission, and am needing some help with winter coming!!! Anyone???
