What does the fuel thermostat do? It's the thing on the side of the IP
that the fuel line with the pre-filter goes to. The plastic connector
is broken on the 602.962 I just bought, and the fuel line that should
be connected to it is connected directly to the large fuel filter.
Would that contribute to the more than usual smoke on acceleration
that I detect?
The fuel thermostat opens and closes the fuel warming loop that feeds
fuel thru the coolant/fuel heat exchanger to minimize/prevent fuel
waxing/clouding in cold weather. If you have excess smoke, it's
unrelated to the fuel running thru the heat exchanger or not. It could
be a bad timing chain (but probably isn't). CHECK timing chain stretch -
if you've got a chain bad enough to cause smoking, it could fail at any
moment. Most likely it's something much less expensive to fix (like
incorrect ALDA adjustment, plugged/dirty air filter, or even a plugged
fuel filter. Give the car some Italian tune-ups and some sustained
highway driving and see if the smoking decreases. A Chevron Techron
concentrate treatment won't hurt either.
