Repair Questions and Answers
Question: 1991
Pontiac Lemans mileage: 150,000. I recently had a
car repair done. The timing chain had broken and the
repairman went to test-drive the car after fixing the
timing chain. The oil light had come on, the mechanic
drove it without checking the oil, and the engine froze
up after that. It now needs a new engine. I need to know
if it was an error on the mechanics part. Is there
anyone else that can advise me on what to do?
Answer: Your
engine probably had a timing gear that had a gear with a
heavy plastic coating on it. When the timing chain
failed, it stripped all the plastic off the gear. The
plastic pieces end up in the oil pan and clogged the oil
pick-up. In situations like yours, the oil pan should
have been removed and the broken plastic pieces cleaned
out before the engine was started.
Question:
1991 Pontiac LeMans mileage: 100,000. This
is kind of simple...I have no heat in the beast and went
to change the thermostat after checking all the fluid
levels, which were ok, and to no surprise to me...I cant
find the thermostat. Now I'm not a Mr. Goodwrench
but, I can do some things and haven’t had a problem with
any of the other cars and changing the thermostat.
Part of the problem is the engine is a Daewoo.
There is a reservoir that is separate from the radiator
and the hoses don’t seem to have any connection that
would support a thermostat. So, can you help me
out? If so talk to me like I am 4, so I can
finally thaw my toes out.
Answer:
We are not so sure the thermostat is the problem.
You may not be getting any hot coolant flowing through
the heater. The heater control valve may be
faulty. In addition, check the vacuum lines that
control the doors and the heater ducts.

Question:
1992 Pontiac Lemans mileage:
90,000. My '92 Pontiac Lemans has been diagnosed as
having a failed a/c & heater blower motor relay. Where,
on the car can I find this relay? Is this an easy part
to change? Where can I buy the replacement part?
Answer:
We think it is located under the
hood on the passenger side on the air conditioning duct.
Yes, it is easy to change and most
auto parts
should have it.
