Over the past couple of weeks I have heard what sounds like running water just after I start up. It goes away after a while though. Should I be worried? It's a P1. Cheers, Graham.

I had this on my scooby to, i also had it on a fiat punto, so i wasn't that worried, i think it could be something as simple as water circulating round the cooling system on start-up after sitting for a while.

I had it of a long period of time and my car never blew up, so i wouldn't be too worried !

 

its perfectly normal behaviour, only worry if the car starts to steam out of the expansion chamber, can mean either a blockage or a buggered headgasket

 

Bo()ox.. your low on water (coolant) mate...

check over overflow res and expansion tank (when cold)

I was lossing water from a small rubber hose that connects to the oil filter cooler. I thought i had an internal leak, until i found it :-)..

That noise is water and air rushing around the system. should be water.

cheers

 

I've often got a similar sound at start-up in my Scoob. I thought it was just the sound of water flowing around the heater matrix??

 

thanks I'll check it out.

 

Yes it is water/air flowing thru the heater matrix that u can hear.. However it shouldn't really happen..

It is due to low water level..... Caused by

1. A pipe or the rad or summat leaking Coolant Externally

2. Or in some cases Head Gasket failure External or Internal

 

Mine has always done this, MY98... My coolant levels AREN'T low.

 

I've only noticed this on cars that have had a de-cat exhaust of some discription.
The water level makes no difference high/low it still will do it on start up.

But remember the dealers favourite comment.
THEY ALL DO THAT SIR.

Zippy

 

I second that MY98 has always done it, never used any coolant and has now had 2 coolant changes at services.

It also makes a wooshing when the ignition is turned on, i assume the fuel system pressurizing or similar.

I would have though if you had that little coolant in the system the heater would work erratically?
