    Thanks Peter. if the thermostat is stuck open, would it at least give a little bit of heat although it is going to take longer than usual. i drove it for 30 minutes and no heat all. there is no heat also from both lines to and from heater core. i don't think my mpv es 2000 model have a hvac doors under the dash but I will take a closer look. my co-worker said it might be bad water pump.

Besides that is usually the case

Have to draw out with turkey baster or remove
the degas bottle & wash out if that is what you want

Changing the coolant has nothing to do with no heat

The thermostat may be stuck open or you have a coolant
valve in the heater system to check out or hvac doors under
the dash that hang up

SOURCE: Mazda MPV Coolant Loss (but no overheat)

i had the same thing on my wifes 2000 mpv van...the ends of the radiator are made of some sort of composite type material....it had a slight crack in it....wasn't obvious until it got worse and started streaming water from it when warmed up....even after it cooled enough not to be spewing it was hard to actually see the crack though a few inches long....was hard to even see where the water and antifreeze mixture was coming from until i took out the radiator

SOURCE: 2000 Mazda MPV Heating problem

The heater lines that run to the back of the right rear side gets rusty and start to leak anti-freeze. There is a black cover under and above the RR tire that has to be removed so u can see.

You probably never cleaned the cooling system out.

If you have not get it done by pros.

It seems something is blocking the flow. If the water pump went bad you will know. Rarely ever heard a impeller breaks off like you think. The bearings and the seal break first.

Check and see also if the heater valve is working.

As for the over heating even new thermostats fail. Reverse flush is needed or the procan measure the pressure in the radiator cooling system and edetermine if there is a engine pressure problem. Tools and experience is the key in the game of diagnosis.

No heat blowing cold air.


Do you smell coolant inside of the vehicle. If so then chances are your heater core is going.

I have a 2000 Chevy Venture van and the heat when turned on blows cold. For a while it was still blowing out warm air thru the back vents but now it is all cold. The van wouldn't warm up at all e


needs the water system back flushing out, heater being cold is its blocked up some time a few back flushes and forward flushes with a hose pipe should free up the dirt inside, same with the engine and radiator. there are meany videos on you tube to help you understand how to back flush you engie. but do the radiator and engine and heater separate so the muck does not go back into the engine.

Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.

Heater blows cold air from top vents after running for 1.3 hours


Sounds like you may be able to fix it by flushing your antifreeze and back flushing the heater core. Some car owners cheep out and put stop leak into the antifreeze, others dont change there antifreeze at all. Both are mistakes.
