Screeching Booster Heater

[Steveenduro]

For some time now my booster heater has had a mind of it's own. It comes on intermittently even after coolant temp reaches 90. A couple of weeks ago it started making screeching and grinding noises (like a dry bearing) even when sitting with the engine off after a run. Now over the last couple of days it has started belching out white smoke.

I replaced the glowplug and run-on pump a couple of years ago.

I'm thinking it must be totally shot and that removing fuse 12 (is this correct?) will be the best course of action.

Unless someone has any thoughts?

 

Many thanks

Hi

It sounds like fan motor bearings are dry seizing up or now seized up obviously the unit does get very hot so if its the original myself I would take the unit right off and give it a good clean up cos your looking at around
