Water temp

[33754k]

My car seems to warm up to 90C, then sometimes drop off to 75- with the needle being quite eratic between 90 and 75, as if the sensor is faulty. Anyone got any ideas? CHEERS

Sensors faulty is my guess, and yours

mines been doing the same.. you can do 70 - 80 for 60 odd miles then turn off motorway and your water drops.. my guess is sticky thermostat
