My 2003 ztt is overheating. 5 mins after cold starting the engine the coolant overflows out and empties through the lid due to pressure. The engine oil is still clear though and no white smoke from exhaust, could a faulty thermostat cause these symptoms? Thanks 🙏

Sadly if it blowing the coolant out after only a few minutes that would indicate a blown head gasket. It’s quite common for them to blow only into the water jacket and just pressurise the system. There is a cheap gas test kit on Amazon you can buy that will tell you if you have cylinder gasses in your water system.

Thanks for answering! Is it the “FreeTec Professional Petrol Gas Engine Cylinder Compression Tester Gauge Kit Auto Tool” for £15.65 that you’re referring to ?

@mikesmith22050 it’s the RELD head gasket test kit. It’s about £18.
