MG ZR: Cams & Maps

[procta]

mine stuck open, i was told to put my hand on the rad to feel it go warmer and warmer, if it did that then it was the thermostat, also i changed the two sensors on the water elbow, as these can act up too, one under the elbow is the dash clock, the other that points to the rad is the ecu , now i have heard stories that the one that points to the rad, can make the car run odd. but i have found that to be questionable, the one under, can make the clocks read out, mine under read! so i replaced the two and all is well.
