Help ! Temperature Gauge funny readings
Hope that someone can help, went to go out today as the kids and the wife wanted to go to Sunny Hunstanton for mothers day. Got about 5 miles from home and the temperature gauge shot up the faster you i went.
The light came on to say its overheating so quickly pulled over, popped the bonnet and checked only to find the header tank was at the correct level but was cold with the fan running.
The gauge then went back to normal, and all appeared well, so off we went again, only for it to happen, the faster i went the higher the gauge went, the slower i went the gauge would return to normal, so i drove slowly home and picked the wifes lil run about and off to Sunny Hunny we went.
Got home tonight, checked the level, appeared ok so i run the car up to temperature and the gauge crept up slowly and the fan cut in, beautiful warm air throught the vents, both hoses hot so it seemed like it was circulating ok.
Thought i would go for a run, so drove through town to the main road and blasted it down the main road, at over 80 gauge read 3/4 and kept moving up and down but never put the light on.
I think either the Thermostat is acting up or the water pump has had it, any ideas as i have not had this for 5 mins and this is the 2nd fault, first wipers now this, slowly loosing patience with this or is it just me .
Help please, give me some idea, if it is the pump does it run off the Aux belt or the cambelt.
Help me please
