Brother picked up a wee mk5 2003 1.2 Fiesta for work. It needs a  little work but  was overheating originally due to stuck thermostat so we replaced that and was still over heating when idling as the fan wasn't kicking in. Long story short the coolant temp sensor was done so replaced that and all seems well so far. Fan kicking in when it should and engine idling well ect.

 

One of two issue I wanted to as about.

 

1) Inside car you can hear water like sound when reving/increasing engine speed behind the dash (water going through matrix I presume) is this normal as I have never heard it before on any ford I have owned. it seems to go away when engine is warm as far as i can tell.

 

2) when you remove the petrol cap there is a large hiss of vacum, more than normal it seems. Is there any valves or pipes i can check to make sure nothing is blocked or causing this or is this fine?

Thanks in advanced

 

The rushing water noise is because the cooling system isn't bled properly, there's still air in it.  

There is a fuel tank breather but I can't remember how accessible it is, had the same issue on a 2003 1.4 myself but never get round to sorting it, the car seemed to run fine despite the excess vacuum.

Thanks fro response.

 

I will re-bleed the system and hopefully that helps.

 

will try to locate the breathe hoses and make sure nothing is blocked or damaged that may be adding to the build up of air in tank.

 

Thanks

 

 

just an update, on further inspection the water pump is wrecked, its making a winding noise and when i had the belt and thermostat off you can feel the pump has got a little play in the bearing, no leaks though but the engine is overheating, so i dont think the pump is moving the coolant around quick enough. Is there any tests i can do on the pump before i remove it?
