blower

Just wondering how many of you who have diesel engines use your engine compartment blower when motoring? All the time or under hot conditions?

I have a 2008 Beneteau 37 and this season my engine compartment blower motor would cut in and out just after start up, then run fine. During the last run of the season, it’s stopped coming on altogether. I ran power to the blower motor itself and it works fine. Can anyone help me understand if...
