coolent leak !?

[Mgaz]

Okay.. Cheers for the replies so far.

I do remember something being mentioned about the fan speed when i bought the car. We were sitting in the car and being showed the temperature controls and de-mist function.

In my ignorance I thought he was on about the fan for the interior cabin.

Im guessing then, this means the radiator fan is goosed ?

The car is at home at the moment and i am not, so i can't do the checks mentioned above right at this moment in time.

So.. Im guessing Im in need of a replacement fan? If anybody's got one?

On a side note, if it makes a difference.. I only just worked out how to turn the aircon off and have been driving with the car in ECON mode.

Could this have had the side effect of the fan staying off? And the engine over heating?

1. Fill the expansion tank to the 'max' mark.
2. Carry out the 'demist test' to check that your fan is running on slow speed.
3. If it is, activate the instrument pack diagnostics to monitor the actual coolant temperature. The gauge is useless.
4. Report back.

Have you had any work done on the cooling system recently?


Because the coolant overheated.

Assuming your fan does not pass the demist test.

When looking through your grill at the front RHS you will see the fan - if you see a silver coloured resistor on the fan this is a classic fan failure point and folk replace it with the upgraded gold resistor. You can get those on E bay.

As to coolant caps you need the 140 PSI type - they are clearly marked 140 psi on the underside of the cap.

I've got the digital temperature gauge ... it just gives me one more thing to be paranoid about!

Hope the head gasket isn't damaged , I shall be gutted if it is.



I wonder, could a larger expansion tank be fitted to increase the coolent capacity and lower the risk of over heating from a small amount of coolent loss?

The 1.8T/1.8 is most prone to HG problems and needs watching like a hawk - the V6 is considered less prone to HG issues - i suppose one reason being a V6 has a larger coolant volume than a 1.8.

Im sure i found a post on the dot org forum that stated the 140cap was for use on the diesel?

Also said that the 140 marking wasn't a psi rating.and its about 23psi or something?

Hi,

The 140 cap is what you need - certainly on a petrol car ( i think its the same for the diesels as well anyway - but no doubt someone with a diesel will confirm this ) - but that is the Spec you need - see link below

The '140' cap (that's kiloPascals, not PSI - it's about 22psi), is now the standard for all engines.

Thanks T-Cut , your names been mentioned a few times on here and dot Org

I've also found a 140 cap from here : https://www.eurocarparts.com/ecp/c/M...d6c5136&000263

but the picture looks strange? what Am I looking at? is it a BMW expansion tank?

Anyway, as long as its the right thing, I'll buy a new cap to be on the safe side.

The cap advertised on the above link is what you need

Nooo, that's not right https://www.dmgrs.co.uk/products/rov...-petrol-diesel
