I've noticed recently that my cars overheating. I checked it last weekend and everything seemed ok but I dont think the cooling fans are kicking in. I checked the fuses and they also seem ok as well as the connections. Can anyone help me please? Its only happening when the cars stationery for a period of time.

Water pump not operating effectively?

Is the interior heater working as it should?

Check the fan relays. If they are faulty I have a spare set for sale. Smile

In the fuse box in the engine bay, take it out and put 12v across it to check it clicks.

Check the temp sensor at the bottom of the rad on the left hand side, the sensors go faulty and the wires corrode, seen it a few times

Right guys, I've found the culprit! Matt, you were right! Its the wires on the temp sensor and one of the wires has corroded and basically broken so I really need to fix this now but I dont know how. Does anyone have any tips? All I can think of at the moment is as the wire is so long from the loom then get a one from a scrappy and basically cut it and splice it together with another one....

Anyone got any bits laying about? Wink

Cheers
