Hello, have'nt posted for a while but now I'm really needing some help!!
Noticed the other day that my temp gauge (1.7 tdi envoy van) was higher than normal (about half way up) and kept quickly going up and down between the quarter and halfway marks and that I could'nt get the fan in the cab to blow cold.
Anyway I had a look under the bonnet the next morning and found that almost all the water had gone from the header tank, so I filled it back up and went for a test run, but had to come back when it started screeching constantly.
At this point I remembered that about a week ago I noticed I could smell something getting very hot, but did'nt notice the temp gauge going up more that half way.
I've no experience with cooling systems at all and don't know where to start.
