91' mercury grand marquis overheat and no power steering


Asked by ajc87 Apr 13, 2019 at 01:29 PM about the 1991 Mercury Grand Marquis

Question type: Maintenance & Repair

My car overheated and lost power steering. I got it
home and saw one of the 2 belts was very loose.
The fan was hanging down and all the coolant had
been sprayed all over the engine. The radiator
looks like it emptied. Idk exactly what needs to be
replaced. It does look like there is damage around
where the water pump and pulley connect. Any
help or advice please?

Well for sure you need a new water pump. Can't tell if the pumps drive pulley is damaged. Did the fans clutch come apart also? Where is the fan shroud?

There is no fan shroud. It was like that when i got it. The fan clutch looks fine but i can see some damage between the pulley and water pump but just cant tell which is damged or both. I guess i should just take the water pump out and see? I was trying to get it out but i cant break lose a single bolt. I dont have much car repair experience. Does it makes sense that the coolant would spray everywhere from the water pump going out?


Oh that happens all the time, when the pumps front seals lets loose coolant will go everywhere. I use a very large pair of channel lock pliers to hold the pulley to get the fan nuts loose. I have also used a screwdriver and wedged it between one of the nuts and the shaft then just loosen the nuts one at a time until they are all loose and then take them off. You really need a fan shroud, they help the fan draw air through the radiator. This old you won't find one new, try a wrecking yard.

Ok thanks man. I appreciate the help. The water pump looks like its going to be hard to remove but im going to give it a try


Yes they are a bit of a stinker, just make sure you keep track of where each bracket and bolts go, if you mess up the brackets won't fit back on.


Well i was about 3/4 of the way there and one of the nuts is stripped... And its a hard one to get to. I dont suppose you have any tips on how to remove a stripped nut?


Well you can either buy one of those sockets that bite into stripped nuts(expensive and hard to find) or soak it in some Diesel fuel (overnight if possible) then drive on a smaller worn socket and work it back and forth until it comes free, if it really seized it will snap off the bolt but you can get at it once the pump is removed and then you can get a replacement.
