[1990timeismoney]

Hi all having a few problems with my GT at the moment temp gauge in car rises and goes over maximum.But fan does not always come on and sometimes it does then it will just drop to half way then start to rise again.Some times i get a running water sound in the car.Also keeps drinking water from ex bottle.rad cap seems crap and its got a sard thermo.

Any help much appreciated.

thanks
