Either you have an overheating problem or your sensor is not reading correctly.

does the temp gauge go red?

have you ever changed the water pump?

[bruno4747]

temp gauge dose not go red and have not done water pump
it may sound funny but i spray all wire with wd 40 and it ok again could it have been that or just wishfully thinking but ok now for 3 days

Crankshaft sensor 100%. cost around £20 from most parts retailers and is located behind the left drive shaft, only a small E8 torx bolt holding it in not a big job.
