hi
just a general question about my temperature gauge,
its never gone into the red and has days when it stays in the middle. the puma has had a new water pump, and i have no loss of coolant but recently the needle quite often goes right up but not into the red and comes back down almost immediately when the fan comes on, but it can keep going up and down all the time for about 20 mins when im driving.

thing is although its never gone into the red yet is this a problem or isit common especially on a hot day???

thanx for any feedback
