Hello,

Looking at my engine from the front of the car there is a pipe that goes from the top left hand side of the rad to the header tank. (header feed pipe)

If i were to undo this pipe at the rad end with the car running how far should the water spurt?

Wouldn't this be a good test to see if the water pump is fecked or not working correctly?

At a guess i would say that the water should spurt more than 3 inches which is what i get.

Any responses to this.

Mike.

The pipe is there to bleed air from the top of the rad and release air locks. How far it should be able to pee i do not know.

When i changed my water pump i took that pipe off to bleed air out,and water spurted out about 3-4 inch's.
The rest of the water ended up down my overalls as i tried to push it back on quickly !!

Sorry to gate crash this thread but I wondered how to bleed the system?
I take it then that the little hose that comes out of the top left hand side of the radiator is a return?
To bleed the system just leave the little hose off??

thanks,


Dave

I like to take the top hose off rad and back fill the engine block with coolant,and then fill rad up as far as possible,then reconnect hose.
Top up header tank.
Then start engine,and pull the overflow hose you mention off and as the thermostat opens you should get a flow of water coming out.Thats when you quickly push that hose back on and secure it.
Oh and keep your heater on warm to get flow through matrix.
Thats how ive done it when changing water pump and thermostat
Im down your way (Bude) on Sunday/Monday,so if you can stop the water coming out the sky them days Dave,i'd appreciate it

No need to do that, just fill as far as you can, start engine and fill whilst it is running burping hoses until it reaches level. Why would you need to remove the small hose at all?

Well i took the hose off to check water flow or pressure because there was none getting to the header tank and the hose was not blocked.

Hence question on pressure.

Andy, is it work or pleasure that brings you down to my neck of the woods?

It should be pleasure Dave,but seeing the weather warnings for tomorrow when i drive down,i'll reserve judgement

We usually stay Brendan Arms (Sunday)then go to Boscastle and Tintagel,before heading home on Monday

If you fancy a pub lunch with a view try the Port William at Trebarwith Strand.
Its about 2 miles the other side of Tintagel. If the weather's bad it's a lovely place to sit and watch the sea crashing up over the rocks.

If you've never tried it before the coast road back from the top of Boscastle through Crackington Haven and onto Widemouth bay is also worth a drive. It gets a little narrow in places but the views regardless of the weather are something to be seen and this time of year the road should be quite quiet.

If you happen to see an 02 plate Blenheim Silver P38 in and around Tintagel its a good chance its me. Give us beep.

Have a good trip,

Dave.

Will pop down to the Port William next time :5bcheers2:

Due to substantial wind and rain,we only visited the Tamar otter sanctuary near Launceston on the way back.

I remember seeing a classic range rover last time on molesworth street,driving out of tintagel.
Will keep an eye out for you

Can't remember where I read it but if you pull that hose off and blow down it to make sure there's no coolant sitting in there it bleeds perfect every time.

No idea why but if I don't blow that coolant through it just sits there and airlocks the top of the rad.

Strange but true!

There was a bit of pressure there but not much as I said before because the water came out of the top of the rad but did not reach the header tank and the delivery hose was not blocked.
