To answer markjay's questions:
When the temp gauge goes up, is the engine actually over-heating, or does it look like a guage fluke?
I'ts hard to say really. Tried squeezing the hosing as I was recommended trying, they were not that hot or that tight, so there doesn't seem to be much pressure buiding and I am not losing water.
When the temp gauge goes up, do the electrical fans work? And if they don't, do they start working when the temp goes down?
When the temp goes up the fans do kick in
When the TC light comes-on does the ABS light comes-on as well?
No the ABS light is not coming on.
Also, can you measure the voltage across the battery terminals when the engine is running (it should be ~14V).
That will be my next job.
Thanks for your help, it is appreciated, Red.
