Its been a rough weekend. I drove my 1994 4runner through a pond saturday while camping. For whatever reason, on the way home, the water pump seized up and my alternator stoped working. My problem is now I am ready to buy a new water pump, and nothing at Autozone looks like what I have on my V6. Everything the auto part dude shows me has a bypass tube on the water pump, where as mine is in the engine block. What the heck is going on here???

alternator and water pump both stopped working at the same time?
how odd....
sure it's not the belt?

abecedarian

and I just went to autozone.com and the pic they have for a 94 3vze only has what looks like a fitting for the thermostat.

but the description also says it's not available in my local store, only by special order.....

abecedarian

and this one:

is available.

odd.....

see thats what they had at autozone, and that is not what is no my motor. that hose comes in my engine block, not the water pump housing. The altentor failed the test at autozone. but working fine before that. I am sure the water pump is locked up, I can grab it with the fan off and it aint movin.

If it's on your v6, then the water pump isn't run by the same belt as your alternator. The fan and belt run on a sorta idler pulley thingy, doesn't drive anything. 16307-65030, 16307-65040 are the oem part numbers.

Its not the water pump, its the fan support bracket.

Looks like this:



You will soon learn they are rather expensive. Do a search on here for "fan bracket" and "false water pump" and "fan support bracket" and you will have the answers you seek.

Its very common for this part to fail. Stay away from the cheap aftermarket supports made of cast pot-metal. They tend to shatter. If they are not aluminum, STAY AWAY!

Yeah, to check if your water pump is seized, you need to remove the timing belt, since that's what drives the water pump.

The water pump on your 3.0L will look like this, but it doesn't sound like that's what you're testing right now. Like DC mentioned in the post above, maybe you're trying to turn your fan bracket? If you're engine is cold, you should be able to spin the fan freely, because the fluid coupling will not be "locked". As your engine heats up, the fan becomes hard to turn by hand. If the fan and fluid coupling are removed and you're trying to turn the pulley behind the fluid coupling, good luck if all your accessory belts are still installed. If you're accessory belts are all off, that pulley should turn freely.

Take a pic of what you're working on so that we can guess less and help more.

yeah your right it is the fan support bracket!! damn you guys are good! it wont spin by hand with all the belts off.

Some of us have been around a while!

Still, others like Abe have been around the block and contracted many-a-disease. Poor guy

Thanks for helping me out. I got a new one for $147 from BAP(local import part store) First thing I noticed was it was lighter than the stocker. I tried to put it on and it seemed way to snug on the studs coming out of the block. So I had my dad( hes electrical engineer,,,enough said) mesasure the holes on the new vs. the old. They were off by little bit(16th's) in amlost all directions. The part has *Made in China* printed on it. Did I get the crapy ones you were talking about??? Is this one any better?-

Unfortunately, I am needing one as well. I have read the other threads about the cheap pot metal brackets, though there is no way in hell I would pick up a cheap aftermarket one, caugh (ebay ). The only aftermarket fan bracket that i am interested in at the moment is made by dorman. Part number 300-801. Rock auto has a good price, seeing as i currently work in a parts house, i will just get a dorman fan bracket through my company.

The best one, honestly, is a factory Toyota one. Alas, they are about $700.

The problem with the aftermarket ones is the cheap metal they are made of, and they are only "sorta" good. Ie the holes only sorta line up. Remember, cheap price=cheap quality in auto parts.

If you get a cheap aftermarket one I'd recommend switching to an electric fan to take a lot of stress off of the fan bracket. Actually some have even switched to an e-fan and removed the fan bracket altogether by getting a shorter belt and removing the pulley.

The water pump with the bypass (the small tube coming out of the thermostat seat) is for trucks with the #2 oil cooler. The #2 oil cooler attaches to the 4" round connection on the driver's side of the block, just aft of the oil filter. Like you, I don't have that cooler. I have 4wd and an automatic, and I think it is one or both of those that determines that we don't have the #2 cooler.

Give yourself a pat on the back for eyeballing the part at the store before you walked away with it. Congratulate yourself for checking here, so that you now know that turning the fan doesn't have anything to do with the water pump.

GSGALLANT

He hasn't said that his water pump doesn't have the outlet for the oil cooler supply on it... all I've seen is that he said his fan bracket doesn't have it (back when he thought the fan bracket was the water pump.)

I'd be surprised if his water pump didn't have the outlet to the oil cooler on it. It is certainly not the combination of 3.0L, Automatic and 4wd that determines that, because the waterpump on my '93 4Runner 3.0L, Automatic, 4wd had that outlet on it.

Maybe the difference is between the 3.0L in trucks not having the cooler that the 4Runners had (which also, I would find weird, but maybe...)

And it's not called the #2 cooler... It is just called the oil cooler. You may be thinking about the #2 cooler hose (there are two hoses that go to the oil cooler... the #1 hose and the #2 hose). And finally, the oil cooler is that 4" round thing on the side of the block that you're talking about above... it doesn't connect to the 4" round thing. Not trying to be mean here... I just want to keep things clear for the others that will be reading this thread.

seems to me that a trip to the wrecking yard to look for a used bracket is in order... or if you cant find one, a ford taurus/lincoln MKviii electric fan...

Thanks for everything guys, Big daddy I would highly reccomend NOT buying the Dorman replacement, I could probably make a better one in my shop with balsa wood. NO JOKE, its way to lite, and it did not even fit on my block, I took it back today. Anyway I like the electric fan idea. I saw some stuff from flex a lite, but it sounds like some are not made to be a primary cooling source? whats up with that? also mt goat said he got a shorter belt( to just go around altentor and crank pulley). Where could I find that? One more thing, if I went junkyard doggin' for a stock bracket, what would be the chances of finding one? Not to mention getting a part out of a beat up truck might solze my problem for only a thousand miles or so intill the bearing in that goes out....
