[DeTomaso] Techno question: a fine mess

Belts are always a good candidate. They start to decay in the air as soon
as they are manufactured and the highway is a hot ozone-rich environment
that can accelerate the process. I just discovered my tires (on the Fiat)
were minted in 1995 and they are so badly cracked I really can't drive it
until I get replacements.
Bend a belt pack and see if there is cracking. If there is, replace it.
But ummm... I think it might be your water pump. I think you can use an
old broom handle as a stethoscope but the angle might make it impossible to
check from your vantage point. I hope it's just the belt.
That reminds me, I have to find an idler pully. Mine fell off :(

>>>Right.A A You'd be amazed at how noisy a perfectly good-looking
belt can
be.
Belts are cheap and consumable; those living in an enclosed engine bay
like
the Pantera's don't benefit from airflow as they do in a front-engined
car,
so probably have a shorter effective lifespan.A A You rarely get
access to
the front of the engine, so now is probably a good time to change them
anyway.
The idler pulley bearing can make one hell of a racket.A A You can buy
a
replacement bearing, then press (or have a machine shop press) the old
bearing
out and the new bearing in.A A But the bearing is expensive, and labor
adds
further to the cost.
Your local NAPA auto parts store has a replacement pulley with bearing,
ready to bolt on, that costs less than the cost of just a replacement
bearing
for your old pulley.A A It is slightly larger in outside diameter, but
otherwise functions identically and allows the use of the same-size
belt.
Part number is Duralast 231036.A A Cost is about $13-15 if memory
serves,
while just a replacement bearing for your old pulley is more like $25,
and you
haven't started paying machine shop costs.
Changing the belts first will determine if you need the pulley.A A If
you
don't, just return it.A A And if you do, have it in your hands and
install that
next.
There, you fixed it. :>)
