300tdi no heater

anyone any ideas, if I drive my 300 tdi at 60 it's ok but has no heater, if I drive it at 70 it cooks but cools down really quick if I slow back to 60, it has no heater at all which is an arse when you need the screen cleared, had a new water pump but screeches like a mouse in acats mouth. Help

are you sure its the water pump squeeling not the belt tensioner ?
have you got a airlock in the heater matrix ?

could be tensioner, was ok after pump fitted but as you say could be air lock will try and flush if it ever stops raining

if you find its the tensioner squelling search on ere for the penny trick will save ya a few ££££

cheers will give it a go

Could it be a sticking thermostat that you have causing the air lock and forvthe squeeling belt try spraying a little baby powder on to the belt that works a treat stops belts squeel

thanks for your reply,think Iwill change stat first and see what happens if I ever get a minute
