Question about Mazda MPV

1 Answer

The Mazda dealer replaced the PCV hose and now the heat doesn't work. When I called them to see if they may have done something to contribute to the heat not working, naturally they said no, and that I should check the thermostat. I need to know how to replace the thermostat.

With engine hot,try undoing the topmost clip for the heater hose to see if you have any trapped air(airlock),turn off the a/c and put heater on full heat/lowfan.if no improvement THEN start with thermostat.(a DECENT garage would have asked you to bring it in and SHOWN YOU what they did and IF a fault was seen not to be their fault THEN charged you for the work.that way,you would have been PLEASED with thier attitude..........)

What is the part name for the hose on top of my Protege DX valve cover?

Just the hose or the PCV (not pvc) valve? The hose is probably a dealer-only item - go to the Mazda parts department w/the broken piece and they'll get you a new one. The PCV is avl. @ most auto parts stores - and is cheap - <$20.

U have a broken hose, replace the hose . Take the broken hose to a parts dealer. Refill the master cylinder that powers the hose,with the proper fluid. One end of the hose will screw into master cylinder.

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.

2005 Mazda 3 idles rough at stop light and sometimes dies

The problem is a faulty solenoid in the vapor recovery system. The solenoid is sticking open and allowing fumes from expansion of fuel in the fuel tank to enter the air intake and smother the engine. This is how the Mazda service tech explained it to me. It is a known problem on the Mazda 3 in various trims which Mazda refuses to acknowledge. Usually the check engine light comes on and the engine diag code reads mass airflow sensor, which is incorrect. I dealt with this for 6 months on my wife's 2005 Mazda 3i before the dealership figured it out. My cousin bought a 2007 Mazda Speed 3 which developed the same problem after a few months and was cured by the same fix.
