305 man to the rescue, maybe!!Firstly I would short out the two pins inside the plug to the thermostatic switch to make sure the fan comes on. If it does, I would then do one of the following things. Watch your fingers!!!!!!!!

1) Ensure that the radiator was topped up fully when changed. With 306's the rad is lower than the top of the engine so you could have an air lock. The way round this is tricky but the manual says to do the following. Remove the filler cap. Place a tube into the top of the radiator tank which is a snug seal around the hole, therefore effectively extending the tank higher than the engine.Locate the bleeder taps on the small 10mm black water hoses. There should be one near the dipstick and one at the back of the engine bay under the drivers side front screen wipers. Release them a few turns, then pour water down your extension tube until it comes out of the bleeder taps. As soon as the water comes out, tighten it fully. Then I would try the engine and see if the rad gets hot and fan cuts in.

2) If this fails I would check the thermostatic switch on the radiator. I believe that it is on the right hand side down low and is made of brass with an electrical plug on it. (this is the plug with two pins that you short out to make the fan come on. There is another switch higher up on the rad which is a level sensor and brings up a warning light on the instrument panel that is bright orange).

Do you need a thermostat in a car?

A Thermostat enables the engine coolant to heat up quicker. One of the advantages is that the vehicle heater will get hotter faster. When the temprature of the engine reaches about 92 degrees f the thermostat opens to allow the engine coolant to circulate to the radiator which maintains a safe temprature for the engine to run at. A vehicle will run without a thermostat fitted. But it is not recommended on some engines as it may cause a hot spot which could cause the head gasket to blow. A typical example being the Leyland O series engines from the 1970s


Is it easy to remove a thermostat from your vauxhall astra estate?

It depends which engine is fitted. The 1.4/1.6 petrol engines require removal of the cambelt cover and cam belt to gain access to the thermostat. This in my opinion is not a job to be tackled lightly. One mistake replacing the belt could mean a trashed engine!!!! The 1.8 petrol engine is quite a bit easier as the thermostat housing pokes out from the side of the cambelt cover. Sorry, don't know about the 2.2 petrol or the diesels.

Why does Thermostat gauge go on and off What is wrong with it in my 1993 ford escort lx?

There could be several things wrong with the system that the thermostat gauge is connected to. You could check to see if the gauge is working correctly. If the gauge works fine, then it could be the housing that the thermostat is mounted to. It could also be a faulty bypass valve near the thermostat which prevents the engine from heating up. Check these places to see what may be wrong with your escort.
