hi guys. Took the capri to work today (about 13 miles) after fitting thermostat and doing few other bits and bobs over the last couple of days.

Car got me there sweet as a nut. Left work, drove about 1mile just about to jump on m4 and i saw water spraying on window. I thought it was starting to rain, but i slowed down slightly and saw water spraying from bonnet. Pulled over and the rad had blown a big hole. The water was luke warm so it deffo not over heated.

Originally when i got the car it didn't have a thermo so should i just take it out again? I'm under the impression that the viscous fan has nothing to do with it anyway. Runs off a different water temp sensor or something.

The problem is (according to AA) that there is alot of pressure in the rad. I'm assuming its because of the thermo.

Any advice please?
