Hi, I've realised my car's temp gauge quickly goes to max within 20-30mins of driving. This also seems to affect the car's performance.

Any ideas what's causing this? I've had the MAF,O2 Sensor,Crank shaft sensor & EGR valve replaced. Do I need to reset the onboard computer? if so, how do i do this?

It's a 2000 W REG 1litre. Appreciate any advice/help. Thanks.

check you coolant level and thermostat

ive been having fun with my coolant system with leaks etc, maybe have a read over my project.
