If that is a picture of your tyres, you shouldn't be driving the van. Regarding your heating problem, it sounds are the thermostat is broken or stuck. You should find it somewhere towards the top of the water circulating system. It is a small circular brass device with a spring and a washer. You can test it by washing it in the sink and then put it in a pan of water and bring it to a simmer. Before it gets to a simmer, the circular part with the washer should raise. If it doesn't, you need a new one. They aren't expensive. The other possibility is that you have a airlock in the system. It may even be that there is no water below the thermostat. This happens after a full drain of the system.

SOURCE: no heat in my 2002 madza mpv.

Two most common causes of your problem are low coolant ( air in the heater core) and a thermo stat stuck open. If you have a temperature gauge and it is reading on the low side. Like 140 Deg or less, you need a new engine thermostat. Feel the top of the radiator tank after the car has been driven. If it is too hot to touch, the thermostat is no the problem. As the system has been flushed and filled I suspect there is enough coolant. Last item on the list is the coolant valve for the heater core. Many cars have a water valve located in line with the supply pipe to the heater core. This valve may be in the engine compartment or under the dash. Check the heater temperature control and follow the cables. One cable most likly goes to this valve. Maybe a cable retaining clop has fallen off

If it is fogging your windows, you have a leaking heater core. Dash removal is required to fix it.

The heater core could be clogged. If your antifreeze is orange , then it is Dexcool antifreeze which causes slime and sludge to build up in the cooling system. It can clog a heater core. My suggestion would be to drain and flush the entire cooling system with Prestone Super Flush. Put in a new thermostat while your at it. Refill the cooling system with a green antifreeze that is labeled compatible with aluminum engine parts and radiators.Do Not refill with Dexcool antifreeze.

2002 grand prix, will not blow hot air, engine heats up fine and cooling system checks ok.


With the engine warmed up feel the heater lines going into the firewall. You will probably find that one is very hot and the other only look warm or even cold. If this is the case the heater core needs to be flushed. With the engine cold remove the hoses at a convenient location and back flush the heater core. Reconnect the lines and warm the engine back up with the heat on.

Olsmobile silhouette temp gage pinned to overheat, where do i locate the water heat sensor?


follow the radiator hose on the driver side of the engine compartment. It will not be an easy replacement, but i would suggest you replace the thermostat also. How many miles on the engine? Have you ever replaced the intake manifold gasket?

Heat only when driving


Hello you can try flushing the cooling system for restrictions or you could have a belt slipping on waterpump pulley or could be weak waterpump. Hope this gets you warm .

How do you back flush the cooling on a 2001 osmobile sillouette mini van


Use the heater hose to back flush the cooling system, they make an adapter kit for what you are doing, it's very inexpensive, it goes in the supply line to the heater core, that is the larger of the 2 hoses.
