SOURCE: overheating engine, but no water

Hi.
A number of possibilities...
1/ lack of coolant in system,
2/ coolant supply to interior heater blocked / controls jammed,
3/ failing thermostat switch to engine fan
4/ failing water pump

#2 may be separate problem and I would check out #3 - after #1, of course!
Hope this helps - if not hold the rating and add a comment below. Cheers, D.

SOURCE: car overheating

Check whether water is coming out of the air bleeder pipe behind the carburator. If not, the heater unit water flow is blocked. You can notice this when turning off the engine. You can hear the water grumbling. at the back of the engine. Normally when it overheats the water flows back to the expansion tank and water will overflow through the cap. Make sure you are bleeding the air well after working on the water system of this car.

SOURCE: overheating engine in 24 valve 96 ford taurus 6 cyl

the thermostat can be easily changed from up top, the T-stat is located at the engine end of the upper radiator hose under the flange the hose connects to. Make sure u follow manufacturer's cooling system bleeding procedures when you refill after the T-stat is changed out.

Should the cooling fan stay on constantly?


No.

If the cooling fan stays on permanently when driving it means that your engine is overheating - and you would notice the heat!

Check your coolant level though.

It's probably the (faulty) switch that kicks in when the engine gets to a certain temperature .. like when idling along in heavy traffic .. and not switching off when the temperature drops.

An easy fix, assuming all is okay with your coolant system/cylinder head.

Give a mobile mechanic a call. These guys are good and cheaper than a workshop call out.

My fiat Doblo cooling fan stays on when engine is switched off


A significant number of cars have an electric cooling fan supplied by a battery live rather than an ignition live because it is believed the cooling fan should be able to start or to continue running after the engine has been switched off.
Coolant will continue to circulate after switch-off due to thermo-syphon activity and it could reduce mechanical stress on engine components to continue cooling.

Some people modify the cooling system by fitting an additional manual switch to over-ride the thermal switch for use when standing in traffic, for whenever continuous operation is desired or to use in emergency should the thermal switch operation fail.

In the absence of such a modification that has been inadvertently switched on the fault will be due to a faulty thermal switch, a faulty or stuck relay or shorted wiring. Disconnecting the thermal switch should stop the fan and if it does it indicates the switch is faulty. The switch is mostly fitted into the radiator header tank but sometimes is fitted to the bottom tank or the thermostat housing.

Why does the heater blower stay on when the car is turned off and the keys removed its a bmw


are you talking about the fan blower inside the car or the fans under the bonnet..? the fans under the bonnet may stay on for a while after the engine is switched off to prevent heatsoak. This is when the engine actually heats up more after switch off due to latent heat within the engine. The fans will remain on until the coolant temperature has fallen and stabilised, then the fans will stop. If the blower fan inside the car keeps running, this may be a feature on the car to assist with heat soak but I would think this is more like a faulty power relay or fan controller if the car has climate control..In this case, my advice would be to consult a qualified autoelectrician.

My 1999 plymouth voyager van's radiator fan constantly on


There is a fan relay in the fuse box in the engine compartment. Usually that is the reason why it won't turn off. It fuses in the on position. If you have the manual it will say which one is the fan relay. just pull it out and get a new one. They are not expensive.

Hope this helps
