Help please!! Have a little issue I was driving along and my temperature gauge shot up and temperature/coolant light came on, so I stop turned car off checked levels ect and all ok then on again and no light and gauge was bang on?? Got the car home left it for a few hours so car was stone cold started car up and temperature went straight to 90, so turned it off and on again and temperature shot up to 120. (Car never smelt hot and wasn't boiling coolant but notice a hissing noise when I turned car off)
Left the car for a day got a mobile mechanic out and the car run fine temp was at 0 but got to dark and didn't have time to warm up to see if it happens again.
Thanks in advance
