1989 240 DL Squeeling

Some days when I start it up and give it some gas I hear a squeeling from
the engine. Other days I dont. On the days I do, it goes away after running
for a little bit. Any thoughts?

Also, I just got the exhaust replaced...went from the CAT, with a pipe
directly to the muffler...nothing in between. This ok? I figure less
constriction of air.

Are you sure it's coming from the engine and not the blower motor?
 
when in the car and I rev the engine when I first start it up....it sounds
like its coming from the engine compartment. Where is the blower motor. What
does it do im new to volvo repair and mods. Thanks.

I'm no expert, either, but I'm unfortunately familiar with this particular
problem, which is common in 240s. The blower motor is kind of what the name
implies, the motor that runs the blower for your fan/heating/air. When they
start to go, they make the most godawful squealing, and it's a big/expensive
job to have it replaced.
 
Hi Peter,

Re the "squealing":
Could be the drive belts (fan belt etc.). This could easily be confirmed by
getting a can of "Belt Dressing" and spraying the belts while the engine is
running and squealing. (Mind your fingers!) If the squealing stops, you've
identified the culprit.

The belts will have to be replaced eventually, but I'm still spraying after
220 000 Km from new.........

Good Luck.

Sounds like the engine belts. Volve had a Service Bulletin.in the early 90's
to replace the crank pully. It wasn't a recall, the SB's were for a customer
who brought the car in for service and we would check for that problem. Call
your dealer and have them do a DCS on the car. If the SB is still in effect
they may do the work under warranty.
 
First option, start engine and run a fine spray of WD 40 over the fan belts.
 
I will certainly check the belts first tomorrow. The sound does not happen
at all unless I rev it....and it only happens for the first two times I hit
the gas, then stops
 
Aha! When you rev it. Sounds like loose belts. Traction is OK without
stress. When drive pulley accellerates, the belt isn't tight enough to
follow, so it squeals.

Also look for belt-driven accessories sliding forward on their mounts.
This will cause bad squeal, and eventually belts twisting over in their
path and breaking. Caused by rubber mount bushings (on the underside of
these accessories) deteriorating, letting the accy. shift forward - now
it's pulley is out of line with the drive belt's other pulley. Happened
to my '86 240.

Mine ('92 245) made a squealing noise for a week or so. Then it stopped,
and very shortly after I realized that the squealing had been the belts
running the alternator and water pump shredding. Fortunately, it was late
on a hot friday afternoon with fairly heavy traffic.

Change the alternator drive belt and apply the correct tension to it.

Cheers, Peter.

It may not be just the belts but belt alignment. As I recall, the alternator
uses 3 rubber mounting bushings and the power steering pump uses 4 bushings .
All are the same type and can be ordered off of the net for about $2.00 each.
The bushings get old and soft and no matter how much tension you put on new
belts, you will still have squeal as the alternator is out of alignment. I
replaced the mounting bushings on my 240 and the belt noise disappeared.
