I would get in touch with one of the traders on here.

Agreed, something does not add up here. Shame youre not closer to me, I would take a look. Are none of the traders on here close to you?

:wot::wot::wot::wot:

With this taking place while the engine was idling, I would still be recommending a close look at the operation of the cooling fan.

I do rather feel with respect, that the OP is missing the point here - there may well be leaking pipes, but I would want to know why before I replaced anything. The coolant does not pressurise and boil over without reason.

Omg this is doing my head in :((

I will ask what is causing the coolant to boil out of the radiator cap then.

Anyone on this forum who lives fairly close?

No offense meant Brainking!:)

You might need to be pro-active and ask the garage exactly how they are reaching their conclusions.

Well they said they did a pressure test and found a leak in the coolant hose. They said it has corroded in and they need replacing. So the leak wont have anything to do with the coolant boiling over? And if the fan works behind the grill (they can only test this by linking it up to an external battery atm right..?), then it means the thermostat is stuck closed? Or will it stop once the hoses are replaced to stop the leak?

Yes ask the garage, In my opinion they need to,

If there is a leak or damaged hose replace it,
Fill the system correctly with coolant,
Run the engine and check the low speed works on the radiator fan,
Check the thermostat opens at the correct temperature.

The low speed can be tested by pressing the demist button when the car is first started.

Sam, go to bed.:bed:

Tomorrow with fresh eyes read posts 18 and 19 which tell you clearly how to test the fan.

Of course leaking pipes are a problem, and they need to be fixed as well.

Night night!:bigsmile:

I know you said u can test the fan behind the grill by pressing the demist, but at work someone said the fan which is behind the grill and the fan behind the dash are different and the dashboard fan demists the car and doesnt involve the grill fan. Is this not true?


Also we cant really run the engine for long because it will seize up if no coolant is getting to it hence leaking.

That's not true.

It won't seize if the leak is repaired and fresh coolant is put in as per my previous post.

As already explained, the fan behind the grill is also used by the air-conditioning. So when you press the demist button, the fan behind the grill should operate because that's where the aircon condenser is situated.
