My 97 Gmc Savana,6.5 turbo diesel's vacuum pump is not rotating at all times when engine is running,causing my fan belt to squel like the hammers of hell.Is it supposed to rotate all the time?Or is it worn out with 227,000 miles on it?They run around 200 bucks for a reman one and I want to be sure Im right by replacing it beforehand.Can the get clogged up and be cleaned out at all??
The pump will stop rotating,usually at engine startup then rotate after a minute or so,and it cuase hard lag on my alternator while its not rotating.Sorry for the after the fact edit.
