Question about 2000 Mazda MPV

Open Question

I just replaced the rear heater pipes lines, & burped the system. The rear heater not getting hot. It seams like it's not circulating to the rear. (fluid @ the rear & heater core is good) front heater is fine nice and hot.The temp stays @ 1/2 way on gauge. the main big heater hoses off the t-stat are hot& have small flow.( Is that normal? Could this be a t- stat not opening all the way? or something else?

    could the rear core be clogged? Are there any vacuum controlled valves along the lines to the rear? I don't think it's the thermostat. I see something under the driver on the line--is that a valve or what? Diagram also shows a valve in the rear control unit. Did you check that one?
    Sorry, but cannot put the pic in this window.

No such pump! Make sure you have anti-freeze in the radiator. It circulates better than just water, because water boils and turns to steam (goes UP) proper antifreeze helps it not have pockets of steam/air.

SOURCE: water not circulating,we put on radeator cap water pump ,intake gasket,flush heater core,engine radeator,reservoir

sounds like your air locked inside there should be 2 bleeders one by the thermostat and in the front of the engine near the pulleys you will probably need a 5/16 or 8 mm wrench to crack them open do one at a time while running make sure all the air gets out and you get a steady stream of fluid coming out once it is bled or you think all the air is out go inside the car and see if you have constant heat if you do then all the air is out.also turn on the heater while bleeding it.

SOURCE: check engine light came on, all fluids good,

You might have heard this,but check your fuel cap,if you did this,change your air filter,If that dont fix your problem,take your car to autozone and have them check the code,It doesnt cost anything.The temp guage is electronically sent to your dash,so check to see if it came disconnected off your thermostat,or from behind the inst,cluster.and check for any loose wires to the thermostat connections.

Will an air pocket in the coolant system cause it to overheat or over pressurize on a 2001 Nissan Sentra ?


1. The radiator cap if working correctly it will release pressure in the system provided the cap you have is the correct pressure setting. If you are having a problem with pressure then replace the cap with a new radiator cap with the correct pressure setting. Do not use a cap with a pressure setting other than the original equipment pressure spec. So you do not go to the parts store and buy any radiator cap on the shelf that fits because they come with different pressure ratings and some of these will be totally unsuitable for your car.

2. If the pressure valve is stuck in the "old" cap the pressure release system will not work.

3. Overheating
Air pockets in the cooling system can definitely cause overheating and can retard coolant flow through the system. If you are draining the radiator to replace the coolant or replacing the radiator you need to follow the correct procedures for bleeding air out of the system for that particular engine after coolant refilling. Some engines have bleeder screws on the cooling system to assist in the air bleeding procedure and some don't.

There are various causes for overheating so don't assume it will necessarily be solved by bleeding any remaining air from the cooling system and replacing the radiator cap with one that works.

Other causes can be...........
1. Faulty cooling system thermostat. (Replace the Thermostat)
2. Faulty water pump, especially if the impellers have corroded away or have disintegrated in the case of those design genius water pumps with plastic impellers. (Replace the water pump)

3. Cooling fans not working and if so the cause needs to be tracked. Check that your fans are kicking in. If the engine is overheating the fans should be running because they will switch on when the coolant reaches a specific temp and well before the coolant gets excessively hot.

4. A partial blockage in the coolant passages inside the engine but not in the radiator if you have a new one. If the coolant is not changed at the required intervals(frequently the case with many owners) or is over diluted with water you can get a build up of debris. If products like stop leak have been used in the system this can create similar problems with partial blockages inside the engine coolant passages.

5. A compression leak into the cooling system.
If you have bled air from the system and have continuous air bubbles in the cooling system I would suspect a compression leak. In that event a basic leak down test will show if you have compression gasses leaking into the cooling system and from which cylinder(s). The spark plug is removed and compressed air is forced into the cylinder via the spark plug fitting and air bubbles will show up in the coolant of there is a leak into the cooling system.
--------------------------------
Have the problem with overheating addressed immediately. Running the engine with an overheat condition will cause expensive engine damage many times the cost of fixing the overheating issue.

Front heat blowing out cool air. Just flushed the system yesterday and got the air out and still nothing


With the vehicle up to operating temperature feel of the heater hoses going to the front heater core. if only one hose is hot then you either have a plugged up heater core or an air bubble trapped in it not letting water circulate. You might try loosening the top hose and try to burp the air out of it. Of might have to remove the hoses and try to blow compressed air through it backwards to free up the blockage.

1995 saturn sl2 heater blows but doesn't get hot


Could be several things. First, when car is fully warmed up, open hood and feel your two heater hoses coming out of firewall. Make sure your heater control is on hot, both hoses should feel hot. If only one is hot, your heater core inside heater case is either restricting flow (clogged) or an air pocket is restricting flow in your coolant(need to "burp" system-get all the air out of your cooling system) . If heater core is good, and circulating good, then you may have a temp. control door that is inoperative under dash, and not allowing air to move over your heater core. Good luck.

Low coolant light flashed stopped topped reservoir read label wrong saw dont fill engine damage can result....got back on road an check engine popped on pulled over wound up losing two or three litres out...


Your most likely problem is a bad head gasket.If you used the bleeders to remove the air from the vehicle and your are sure you got all the air out and you still have no heat and the coolant keeps coming out the over flow bottle.Then the head gasket is bad.Usually the rear head head.But I have also had the front head go bad.The best is to replace both gaskets.You should also have the heads checked to make sure they are not warped if the engine ran hot.Hope this helps.Good luck.Let me know if you have anymore questions.

1991 Subaru Legacy - non turbo Car runs great !! Except my daughter rear-ended another car - it seemed like it did not hurt it but now it keeps going hot. At 1st it was overheating - replaced thermostat...


When your daughter rear ended the other car, she could have caused one hose somewhere to get a kink in it. Please follow especially the pipes underneath to check for a kink. It may be a very small hose but it can cause this problem. It did it to my 1990 VW Golf GTI.

It could also be that there was a metal pipe that bent also and water is not circulating properly.

1995 GMC suburban temp guage pegs high, but heater


Sounds like there may be an air pocket in the system.
Try 'burping' the system. If this still doesn't fix the problem, check the temperature of the heater core hoses (in and out) The inlet should be fairly cool, the other should be piping hot. If they're both cold; the heater core has an internal blockage.

Next, replace the thermostat with a winter (180-195 F) derivative.
Bleed the system accordingly, and keep me posted!

Replace leaking radiator 2000 Grand Jeep Limited V8


Radiator removal is not that difficult but too long to write out. Pretty much it involves removing the brace above the radiator and any fans, hoses and lines attached to it. When re-filling do so with heater on full hot to allow coolant to circulate fully through system. I prefer to run engine to the point that temp is at about 200, then turn it off for a few minutes, the thermostat will then open and you can re-start and begin filling again.
