Hello
.
Just wondering if anyone could help be out with a small problem I have with my 300 tdi discovery?
On my way to pick my daughter up I noticed the heater was blowing cold air with the temp gauge at normal running temp.
When I got home I decided to bleed the system.
I took the top off the header tank then the bleed nut on top of the radiator, after 30 seconds I was getting a nice flow with no bubble so put the bleed nut back.
I then moved on to the other bleed nut, loads of air and it took a good 5mins and a lot of water before I could put the bleed nut back.
Still blowing cold air at running temp.
I then take off the left hand side water pipe that goes into the bulk head, no water coming out at all, after 5mins at 3000 revs and a lot of spluttering from the water pipe I finally get a good flow of water so put the pipe back on.
Then I have to drive to leeds {no choice} on my way home the temp gos into the red without any warning {still blowing cold air}.
I decide to phone the AA because i`m a good way from home and was thinking along the lines of damage limitation.
AA came out and did:
Pressure test {engine off} passed with flying colours
Pressure test {engine running} pressure built up to 15psi but no temp increase.
Sniffer test, passed with flying colours so head gasket is ok.
Hot water is going all around the engine except for the right hand pipe that goes into the bulk head .its cold with no water
And I did notice the water pump squealing quite a bit .
AA verdict was not sure but should be ok to drive home ..
Any ideas?
Thankyou
Shaun
