I've recently been having problems with my temperature gauge. Instead of starting off cold and slowing moving to a steady reading in the middle, it fluctuates wildly. I find that in neutral, the needle drops to C even when revving the engine, but upon engagement of the clutch and during acceleration, the needle rises to the usual central position. Has any one else had this problem and if so, any idea of what would be wrong? It wasn't a major problem in the winter but now that temperatures are rising, I don't want to risk overheating the engine unintentionally.
Thanks
