Astra 1.4 %26quot;N%26quot; reg. Heater works fine at low speeds (30-40mph)
after that it goes cold. I think I may need to change the
thermostat and wonder if there is an easy way to do this or
could there be another reason for this problem.
Help appreciated. BillIs there an easy way to check/change thermostat on Astra?It does indeed sound like your stat is jammed open. So long as you're not losing water, that is.
If you can't get around to changing it (what with it being f-f-f-freezing at the moment, try blanking off the bottom half of the rad with tinfoil (just like everyone did in winter in the 60's and 70's) to raise the temperature a bit.
A good double check, is to see if your oil filler cap is covered in %26quot;mayonnaise%26quot; on the inside. If it is, the engine's being overcooled and not getting hot enough to drive off any condensation.Is there an easy way to check/change thermostat on Astra?its not your stat, sounds more like a vent prob, make shore controls on recirculate, the curled arrow,Is there an easy way to check/change thermostat on Astra?mmm, they work, or dont work, speed doesnt matter...
sounds like its jammed open, so its not heating up properly, or the header bottle is empty...
thermostat housing is at teh end of the top rad hose... and do it cold, or youll scald yourself... and doht forget to change the gasket.Is there an easy way to check/change thermostat on Astra?No easy way to change the stat. Being an 'N' reg could be the water pump on its way out. As the belt turns the pump quicker it is not coping.
