COOLANT TEMPERATURE GAGE

2005 MG ZR

Engine Cooling problem
2005 MG ZR V12 Two Wheel Drive Manual 52000 miles

Bizzare one this! When I reach 70 mph, the needle for the temerature goes down to bottom within seconds. The heater still works and I get hot air through. When I drop speed back down under 70, the gage goes back up to normal within a few seconds! Any ideas or heard of this one before?

Check for loose connections on the gauge wiring. Sounds like the temp gauge is losing its power signal !
