Hi Im sure im stating the obvious but you are putting the thermostat in the right way up ( im not even sure it can be put in 'upside' down but check the parts manual for the correct installation )... you are using the correct temperature range thermostat ??....Once the temperature has risen the thermostat simply opens up and lets water circulate to the radiator via the left hand (drivers) large hose etc, you are saying this hose doesnt get hot at all with the thermostat installed, is this the same for the pipe at the radiator end? ( Be careful of fans switching on while you are under there :) ) if not then the water is not circulating to the radiator, either you have a big air lock at your radiator or your pump is not doing its job, is this an origional D pump or one from a D vender ?? Have you bleed the radiator from the little hose at the top ( careful removing this its a plastic nipple on the rad ) Make sure your pump bleeder kit isnt blocked up disconnect from the tee end and blow hard down the end, make sure this bleeder hose is installed in an upwards direction so this doesnt air lock too!.

No water in coolant pipe where to otterstat is located, no water circulation and fans do not come on-because no water in that pipe. Hoping a 3rd thermostat is the trick--can't think of anything else. > > Harold McElraft <hmcelraft@xxxx> wrote: > You're air-locked at the radiator.
