an easy one for everybody... recently acquired the car and was wondering if the temperatures it runs at are right, i believe the car has been stood a while altho it has a new radiator, fitted up on perchase... the range of water temps it runs at vary from 75c - motorway - all the way upto 95c in traffic (the traffic cleared at this point)... this seems quite a big range to me... oil sat at 90c, never moved... will fit a new thermastat regardless... one other thing, what temp shold i expect the fans to come in at?? any feedback much appreciated... watto

It's what these cars usually run at. No need to change thermo. Fans will kick in around 100. Oil temp won't go above 90 unless there is a problem or you're giving it stick on a track.

Changing the rad for a Nissens alloy unit will slightly reduce the running temp (although, not by much) and they won't corrode, unlike the rubbish rads Pug produced Thumbs up

How old is the oil?

75 is too low. Our cars use an 83 degree thermostat so once warmed up the temperature shouldn't be below 80 really. I suspect you have a leaking thermostat, most likely due to the seal rotting.

edit: The upper ranges of the temperatures you are seeing sound normal though Smile

Would the thermostat leaking like you say be enough to cause a noticeable drop in coolant?
