Coolant leak from inside of fan pulley?
I have a very sudden and very prolific coolant leak from inside of the fan pulley, like along the shaft of the fan where it comes out of the engine block!
Has anybody here ever seen this? Thanks! Sam |
Sounds like it's time for a new water pump...
|
Yep, water pump.............Dont drive it until its fixed.
|
x3 just replace it and your back in business :)

There is a weep hole in the shaft housing. When it starts leaking like that it means the seal is wasted, maybe the bearings too. Grab the fan and see if it wiggles up/down, side to side. If it does, then pay close attention to your fan clutch as well. It could be worn and vibrating which will shorten the life of your next water pump.

OK, now I'm getting it, thanks to you guys! I didn't see before that the coolant pump is bolted right to the engine.
I'm going to try to replace it myself. (yikes) Are there any guides? Thanks! |
clutch fan needs a special tool to get it off.
do a search on w.p. removal. look in your manual. those are my tips. one last tip: helps to say what year truck and what motor is in it. |
It's a 1993 straight six.
Bummed if I need a special tool. :( |
There is a big nut that you need to back off in order to get the fan off the six. Since the fan motion tightens the bolt, it can be stuck on there pretty good. You definitely need the special tool.
Not to scare you, but the last time I did this, I could not budge the nut even with the tool. I just about busted both arms trying to get it off, and I'm a pretty strong guy. I ended up putting a big crescent wrench on the nut, securing the rented tool against something like the radiator support, and hooking an engine lift into the end of the crescent. I lifted the front of the truck up a few inches before it popped loose. The next waterpump that had to get fixed went to the shop. |
some can be a pain in the ass to get off.
andy, any of the 13 fires burning in california darkening your sky? |
The one in Auburn is kinda close, but we're upwind of it so things are pretty clear here. We live in the burbs and are pretty well insulated from the fires themselves, but last summer there were a few days I didn't even dare to go outside there was so much smoke in the air. So far it's been good this year.

i have relatives that live in upper pasadena a couple of blocks from where i used to live.
the fire is 10 miles or so away. the air quality is very bad and not getting any better soon. prayers to the 2 firefighters that died and all the other firefighters battling the fire. |
Well, I have a crescent wrench that will fit around the fan nut, and a hopeful way of holding the fan pulley, but first I need to remove whatever that plate is that the fan is attached to. Problem is, there is some wierd coil thingy in the way of getting that off. They didn't mention that in the autozone guide, which isn't very detailed:
Drain the cooling system. Disconnect the lower radiator hose from the water pump. Remove the drive belt, fan, fan spacer, fan shroud, if so equipped and water pump pulley. Remove the alternator pivot arm from the pump. Disconnect the heater hose at the water pump. Remove the water pump. |
you do not remove the coil thingy.
the tool is to hold the fan pulley. do yourself a favor and rent one from your auto parts store. disconnect the fan shroud and put some cardboard between the radiator and the fan. you will not like it when you mess up the radiator if you do not do this. read a whole bunch of posts on this before you start on this job. |
The autozone website is wrong. Try doing a search, this has been covered before. Remember that the water pump on the six is attached to the fan in a different way than the 302, 351, or 460.
