Mondial t overheating

First step would probably be to try changing the thermostat - it could be sticking. Next thought would be a water pump on its way south or the radiator......

I.

 

My T does exactly the same thing, fine at speed but overheating in traffic, I changed the temperature sensor in the radiator as the fans didn’t seem to be working. New sensor fitted & fans cut in at 90c.

However the problem continued, on a test drive things seemed ok (still a little warm - but it was a hot day) anyway while taking my car for its major service the problem re-appeared, initially things were fine, probably because i was travelling on a major road (for over an hour) temperature was at 90! However as soon as i changed to smaller roads & speed reduced the temperature started to climb (hitting 115 at one point)

After some research it seems that (from the 348 forum) the fan connectors can corrode causing the fans to run slow or stop, I have passed this information onto the workshop & lets see what happens! I have asked them to flush the system & have fitted a new thermostat anyway.

If this doesn’t solve the problem i will have to do some more work!

I will post up results whatever happens!

 

a former colleague collected his brand new T from the factory. On his drive back to London and hitting high temps he dropped it straight into Maranello UK.

They discovered fans were incorrectly wired and resulting in fans on at low temp and fans off at high.
