Hello boys and girls!

I do hope you lot can give me an idea of what may be wrong with my car - or more so what i've done to it!

Basically the car was heating up fine, and the temp guage sat just slightly below half way on the reading, which is in the normal range however now its sitting barely into the normal zone even after a long/hard drive out. the reading barely reaches the "N" of normal.

Now like i say, it was reading fine, until i removed the temperature sensor to gain access to a glow plug - which also meant draining some coolant.

I refitted the sensor the same way as it was previously installed and i refilled the coolant reservoir up to the full mark with a random mix of water and coolant.

Now, im wondering why my car is overcooling, could it be that my coolant/water mixture is overcooling the engine and wants changing, or could it be the sensor isn't working properly?

I cant test the sensor and dont have a spare tenner for another one unfortunately! [xx(]

any info will be a great help because Mr.Haynes is hopeless

Chances are you have damaged the sensor when taking it out, or that you have managed to trap a pocket of air in the housing where the sensor is fitted.
Can you take the sensor back out slowly and see if any air comes out?
Also, if you feel the top hose does it feel unusually cool after a run or as per normal?

Failing that it might be coincidental that the thermostat has failed and is stuck open

Hi I do not know escort diesels very well but you may have a air lock.ie the sensor is not in contact with coolant.Are there any bleed valves that you can loosen or try loosening the temp sender until cooland comes out. Hope that is some help.

cheers lads i'll try loosening the sensor until coolant comes out and then retighten, there were no "air bleed" proocedures in the haynes so assumed it would be okay just to bung it back in - i do hope its as simple as this though!

Metal, if you look on the rubber hose at the front of the engine bay you will see a small round thing with a slot in it, that is the coolant bleed valve. Warm the engine up and slowly undo the valve, leave it off until you get a smooth flow of coolant. You can keep the system topped up during this through the expansion tank.

also make sure the connector is clean as well as the top of the sensor where the wire connects,this if a bad connection can also make the gauge read wrong. [;)]most likely an airlock though

[:)] Thom mate, you may have an air lock in the coolant sytem,in which case you will have to "bleed" it, it is possible you may have damaged the sensor taking it out, Also if it was running "cool" to start with, the coolant system thermostat, may be stuck in the open position, that is if a previous owner has not taken the thermostat out completley, which is an old dodge to get around a faulty thermostat, if they start overheating in summer, and a lot of people just don't bother to replace them.[:T]
If you need any more info/ help PM, But I am just departing for a couple of hours fishing,so don't worry if there is a delay in you getting a reply.

cheers lads, groundhog, i'll see about the bleeding process described above and if that fails i'll contact you tonight/tomorrow!

The help is much appreciated because im new to this car thing.

On the upside i serviced it (partially) and i did it all by myself with relative ease, glow plugs, air+fuel+il filters, oil all changed with minimal problems [:)]

if car was starting ok, why did you change glow plugs?

Because it wasn't starting as okay as i'd have liked, and it was in major need of a service.

the service could of made it start better without changing the glow plugs,they only usually change these when they have to.did you get the temp gauge working properly again ???
