#1864 of 2547 Re: Changing the thermostat 2000 Mazda 626 2 5 liter engine [Mr_Shiftright]
Sep 14, 2005 (4:07 pm)
It is hard to tell what the exact temp is, as there are no numbers....however, it was running in the "normal" range (to the left of the center of the gauge). When I drove it today, first thing in the morning, I choose not to use the heater/defroster. The temp gauge went up past the center and into the right side of the gauge at a pretty rapid rate. I quickly turned on the heater/defroster at full bore and instantly the temp came back down to the normal range...it fluxuated slightly from normal to the middle of the gauge then settled into the normal range. The heater/defroster started blowing "heated" air just like it's suppose to. Could it be that the thermostat was "stuck" and it may have opened back up? Any other suggestions?
Thanks for you help.

Well okay if your temp gauge is jumping around, that is more likely a thermostat issue. I thought it was blowing cool air with a steady reading in the "normal" zone, which would be more indicative of a bad heater valve or air deflector servo or cable.

Sep 14, 2005 (7:27 pm)
Today, I happened to look under my 1994 Mazda 626 and saw a wire hanging down in front of the rear wheel on the passenger side. Upon inspection, I found it to be small ground strap that was broken, with one end still bolted to the body of the car. I tried to locate where the other end was attached, but could not find it. Does anybody out there know what this ground strap is supposed to be hooked to???

I have had two overflow tank replacements on my 2000 LXV6 model. I believe they are just cheaply made. Their was a design modification as the replacement have not worked. The second replacement was immediately following my 60,000 mile service when I had timing belt and water pump replaced. I noticed some of the coolant laying in an area and was told that it was just a burp in the coolant system and some coolant "just escaped from the overflow". It was a slow leak and shortly thereafter my temperature gauge shot up. You would think that they could design a once piece unit.

I love this car. Best drive ever, not the most comfy seats though. Anyhoo, after many years of loving this car I got another and made the 626 my gas-friendly car to take out when I don't need to lug crap in my SUV. For the past 6 months, it's been tempermental when starting. Some days it just won't. Others, it will fuss and trying again later it will give in and drive like normal.
My father says it has something to do with damp weather but heck, I need the car no matter what the weather is like.
Yesterday it started for a second and shut off. It makes the "starting" noises but just doesn't fire up completely. Does that sound like sparky issues?
#1871 of 2547 1994 626 Trans Problem
Sep 19, 2005 (6:46 pm)
I have a great looking black 94' 626. Its a wonderful car except a few niggling problems and the check engine light that used to come on and off. Well the last couple of days the thing that I was dreading about happened. My transmission or its electrical circuitry has developed problems. The car reverses fine but in drive, it just revs high and starts with a big jerk. Then soon after the 'HOLD' light starts blinking and the car refuses to move. Does this mean that my transmission is 'kaput' or is it just an uncooperative sensor??
Could someone please shed some light? I love this car but lately its grown too temperamental for me.
Thanking you in advance.

This is great ! I could have written this myself. I have a 99 Mazda 626 ES V6 - at about 65,000 miles my water pump went out - a month later all the coolant was on the grount - turns out it was the reservoir tank. I had had a replacement of the reservoir tank at about 20,000 miles also - (same problem ) car got hot and all coolant squirted out of a pin hole in tank.

Sounds like a plan, but I have had the A/C off and received the same problems. I will check into your suggestion. I do appreciate it.
