Title: Overheating Post by: Robert on April 23, 2019, 10:05:13 AM Hi, I went out for a yesterday and the following happend which I didn't expect to be related.
My temperture gauge was giving no reading at all. However I was not worried because the car was cooling fine before, even too cool. However after an hour drive when I parked the car, the car overheated. I could hear the coolant in the reservoir but the fan was not on. Is there a relation between the temperture gauge not working and the fan not going on? I replaced the fan sensor 6 months ago and since it was working fine. Also checked if any fuse was blown, but everything looked fine. I thought it maybe could be the relay that operates the fan, however this wouldn't explain why the temperture gauge was not working. Best, Robert Title: Re: Overheating Post by: Neil-yaj396 on April 23, 2019, 03:01:21 PM They don't sound related. The sensor for the gauge is in the cylinder head on a different circuit.
The fan thermostats are all old stock now and unreliable. I don't like aftermarket kit, but after three thermostats failed on me in three years (luckily two in the 'on' setting) I fitted one of the adjustable ones that takes its reading from the top hose.

Although there may be water in the header tank there could be very little in the block, hence no reading from the head sensor? A long shot I know....

That was my thought Neil, well that coolant is low, |
