I'm new to the forum and have just bought a mk 4 1.6 8v. The temperature guage does not register unless in traffic and posts on the site suggest that this is a thermostat stuck open.
I have seen a kit on e-bay that bypasses the original thermostat and installs an additional one somewhere in the system. Does anyone out there know anything about these - are they any good, easy to fit etc.
The fix is under £20 so if any good must be better than changing the cam belt and water pump etc as the car has only done 40k.
Any help much appreciated. Thanks
