13/06/2003 16:39:29   Nick   I posted a similar query a while ago and tried the solutions suggested. I have drained, flushed out etc the rad system but still not much heat coming out. It has been suggested that the heater thermostat might be at fault but not sure how to access this. There is still a wire from the heater valve (which is working fine)that dissapears into the heater box. Any suggestions so I don't have to drive this winter with my wooley hat and gloves on!!

The wire that disappears into the heater box is the thermostat wire. Check that the heater valve is opening correctly.

Will I need to replace the thermostat? If so is it a straight forward job to pull the heater box apart?

Normally you should only need to replace this when they leak after a long period of being stored dry but if all else fails... Highgates supplied mine.
