Question: HOW DO YOU CHANGE/REPLACE A WATER PUMP ON THIS CAR?

Answer:
To get the water pump off the 3.1 l v6, first release the belt by releasing the belt tensioner.
Remove the 4 10mm pulley bolts. Then remove the 6 8mm water pump bolts.

Have a pan under the car to catch the coolant. Be sure no pressure in the system before you
begin. Scrape off old gasket, and install new pump.

Open cooling system bleeder screw which is located on the top of the pipe just above the water
pump. Fill with coolant. After a few minutes the level will go down as the air comes out. Fill again
until coolant comes out of the bleeder, then close it.

Dont fill up to the top of radiator, as it will expand as it gets hot. After the thermostat opens, then
the level will drop, then fill all the way and re-install cap.

Warning lights- service engine light.

Question: I recently lost my low beams...any cause to this happening?...All other lights work.

Answer:
Answer: First off, the
service engine soon light being on will not cause a problem with the
headlights, but you should get it checked out before a problem gets worse.

As for the headlamps, if you are absolutely positive that the bulbs are good, you should check for
an open fuse. The headlamp switch could be the problem as well and would need replaced. You
would have to check wiring from the switch to each headlamp bulb. If you have no power coming
from the switch, it is most likely bad.

Since it's the least expensive to try, I would get two new headlamp bulbs and start there.

Buick Century Water Pump and Headlight Problems

Question: Car has engine oil in cooling system, no oil cooler, appears to have external timing
cover oil leak.

Answer:
A leaking timing cover gasket would not cause the oil to get into the cooling system. You most
likely have a leaking intake manifold gasket. These are common for internal and external leaks.

If you are going to fix the intake, you might as well fix the timing cover gasket also. Be sure to look
at the cover closely around the coolant passages. If it has been leaking for a long time, it might
have eaten away at the cover, since it is aluminum. If it did, and it is bad enough, the cover would
need to be replaced.
