How do you replace the water pump on a 1994 Ford Ranger 3.0L V6?

Answer 1

o.k. i just did this repair on my truck so i hope this will help someone because it was a bear for me to replace.

1. drain your coolant 2. loosen the fan shroud and let it hang 3. remove the cooling fan. This step is not so easy. you need to by a tool set to remove this. It's only about 15 bucks for a wrench and a tool to hold the pulley. remember that this fan removes from the pulley in a clockwise turn(opposite from the usual way to release a bolt). It's o.k. if you dont get it off, you can just move on but it is in the way. 4. next remove the belt(pull down on the belt tensioner and it comes right off 5. remove the alternator, dont have to disconnect the electrical just unbolt 6. remove the alternator mount. 3 bolts all up front 7. now here's the hard part. There is one bolt on the water pump which cannot be removed without loosening the aircompressor/Power Steering pump mount. so to loosen the mount, you need to remove the belt tensioner. have to have a star bit set to remove the one bolt in the middle and it will come right off. There are 5 bolts on the mount. 2 on the driver's side three up front. the two on the side are obvious. the three on front are a little hard to find but the two hidden bolts are in the area behind where the belt tensioner was at. you dont have to disconnect the air compresor, just set the whole mount with the compressor and steering pump to the side. 8. remove all hoses from water pump. 9. remove the water pump and clean the engine surface to remove all remaining pieces of the old gasket. 10. install new gasket with rpv sealant and install new water pump.

For step 7 you do not have to remove the tensioner, you can use deep set sockets to remove the two bolts next to the tensioner.

I just did this.. it was almost perfect!

1. I did't have to remove alternator.

The Three bolts on the top. Holding the Ac powersteering pump mounting bracket on are hard to find. Some help! One bolt is in the cavity behind the idler pulley and the other is behind the tensioner pulley the third is easily seen between theses two. Also I did this on a 2000 Vin V and no star bit was necessary. Also to get the fan off I think it would be easier with belt on. I already had it off so. I unbolted the pulley and used a pipe wrench on the front of water pump and 7/8 wrench on the shaft
