Heating problem: I have a 1996 buick roadmaster wagon 88,000 miles. sat in garage for years so we've put a new starter in it, new thermostat, radiator is great, flushed it both ways, maybe the vent? anyone...


Sounds like you need a plumber. Check the water flow through the heat exchanger, you may find it only needs flushing through or the blades on the water pump are corroded away.

How to replace water pump on 1993 buick roadmaster


use a serpentine wrench and remove the belt. Remove the large fan. The water pump is right behind the big fan. Get a new one, use a gasket adhesive to help hold the gasket in place and place at least one bolt through the pump before you put it against the motor. Torque the bolts properly. Refill the antifreeze. IF it runs hot, bleed the radiator of trapped in the system.

Steering on a 94 Roadmaster wagon jams suddenly when going to make a turn. Power steering fluid has been flushed and replaced. Problem appears to occur in rainy weather, possibly after going through puddle...


make sure the return hose for the power steering is good and the drive belt is good if the car has over 40,000 Miles on it i would change the belt as well Happy Holidays as always wish you the best of luck Michigan Man.

How do i locate the starter on my 1993 buick roadmaster wagon


Trace the positive lead from the battery. The starter will be towards the bottom of the engine where the transmission mounts to the engine.

1996 buick roadmaster keeps overheating: already replaced the thermostat, water pump, heater core, heater control valve, hoses and anti-freeze


A shotgun approach to repairs can really rack up the bills.

If your symptoms are loss of water and you have replaced the thermostat, you more than likely have an issue with steam. And that steam more than often comes from a bad head gasket. Most head gasket gasket failures seem to be confined to the water side initially, but let it go on bigger damage will occur.
You can buy a litmus test strip to dunk in the coolant. It will indicate if there are exhaust residuals in the water and thus a gasket failure.

However it may just be something simple, given that you have just about replaced everything:

have you given the radiator a good hosing inside and out?
is the radiator fan running when it should be?

How to remove water pump?


You more than likely have to remove the radiator and then you can access the water pump. I had to replace both of mine at the same time, so it worked out fine. In the Haynes manual it says you must remove the electric fan if equipped and also the air pump to get to the mounting bracket bolts.
