Replacing the water pump- how hard?

Well my water pump went out, long story short i had my brother pull me back home and want to do it myself because thats how you learn chit! How hard is this to do? I guess im only assuming its hard because its behind the timing belt and everything? Any help would be appreciated

 

Bump

 

Go for it! I haven’t done it yet but plan to in the fall. There has to be plenty of write ups for the 2uz online.

 

lots of people have done DIY timing belt/water pump replacements. you'll be fine.

 

Is it hard to replace? Can't really say without knowing your DIY mechanic skills. And even then it really comes down to are you comfortable enough with the remove and replace procedure to attempt it. This forum has the most detailed discussions you'll find on the net and several posts that document the procedure from start to finish. Do a search and you'll know pretty quickly if it's something you want to attempt or not.

In my case, I've been DIY wrenching on Fords and Chevys since the 1990's, with a couple of timing chain replacements during those years. I just did the belt and water pump on my new to me 2006 a couple of months ago with no problems. Total time for me from opening the hood to finish was about 8-10 hours. 4-5 hours to disassemble, mark all the bolt locations, take pictures then the same to put it all back together. I did replace my radiator at the same time also. Others here can probably do it in half that time.

I did buy the crankshaft pulley tool for $50 which I think was money well spent along with the expensive form in place gasket maker which has been discussed here as well.

I did it mainly for $$ reasons. Toyota dealers in my area were $1200 and $1600 for belt and pump change. I bought Toyota OEM parts from McGeorge Toyota online and Denso radiator from Napa, total parts for me as around $450.

Good luck.

 

There should be some youtube videos. Search for 2004 tundra timing belt replacement. It will give you an idea of what's involved. You should replace the timing belt & other components while you're in there.

Here's one

I would agree, I have seen many people tackling this on their own. Depending on your ability, I bet you can do it.

Take your time, research many videos and I bet you'll be fine. If you're doing the belt at the same time, make sure you research and get the 'timing' right on it so it all lines up like it should.

*I'm sure you're already doing it, but make sure a new water pump gasket is used as well!

 

It's really not that bad of a job, just takes a while. I made the crankshaft pulley tool out of a 2x4 I had laying around. Just be methodical and label where all the bolts go. I used little sandwich bags. Like said above, making sure the timing marks are correct is extremely important. I used that 1A Auto video a bunch when I did it. Go for it!!!

 

Should definitely clean everything that i come across right ?? That doesnt look good

 

Coolant looks like maybe its been past its useful life?

How does your radiator look? Rusty like that hose connection? If so, might as well do a coolant 2x flush and new radiator at the same time. Removing the radiator will give you more room to work on the Timing Belt, too.

 

Okay soooo i removes this hose and the liquid got all over the place, what was this ??

 

That's your coolant hose, attached to your radiator. That's where your coolant lives.

 

Coolant. There is a drain plug on the bottom of the radiator. Open that and let all the fluid drain out first.

 

Lmao okay i knew that but its a different color from the one on the opposite side .. thats why i freaked out

I think its a lil too late haha

 

I mean, the radiator is also a transmission cooler, but those lines are the thin ones.

 

What do you mean by different color?

What color is your coolant?

 

One was red ish and the other was a clear with a hint of green

 

Do i need to pull the hoses off or can i unbolt them? Theres only one left but the hose isnt budging and i can get a wrench under there to unscrew it

 

No this bucket was used for some cement previously haha

 

My recent experience with the green to pink coolant conversion was that the new pink coolant looks green at some different angles in the radiator. In the reservoir it looks totally pink, but in the rad at the cap level it has a slight clear/greenish tint with a touch of pink. Weird, but true.

 

Do any of you have imessage? That way its a faster way of communicating between us- i dont mind putting my number out there- just text me your tundras name and ill make a group 2109076162 even if you dont have
Iphone ill still make group

 

The smaller lines connect to your transmission. That red fluid is ATF.

Matt, please don't take this the wrong way but if you don't know this then I'm not sure you should attempt the water pump/timing belt. You have the potential to really f*ck up the engine if you don't get the timing right.

I just replaced my radiator a few qeeks ago. All the hoses are easy to remove once you move the hose clamps back.

You need to do some serious research before proceeding.

And again, please take no offense. 18 months ago I had never changed my own oil. I never thought I'd be where I'm at today. Even still, I'm not yet comfortable with doing the timing belt. The risk vs reward just doesn't line up for me.

 

Im actually having a close mechanic friend come do it, i just have to get the radiator and fan out of the way for him. I dont trust myself either

 

Looks like you'll need at least 2 new gallons of coolant. Also, you don't want to mix two types of coolant so you'll want to drain the rest out of the engine block. One 10mm port on each side.
I'm having trouble posting the picture.

I dont have an I phone but I can video call you on what's App and walk you through it if you want.

 

Here are the pics I posted of draining the coolant from the block.

Removing the radiator is very simple. The fan is tricky as it moves while you try to loosen the nuts. You can borrow a special tool from Advance but it didn't work for my 02.

 

I just called it a day and decided id wait till he comes, of course i want to tackle projects so i can learn but this truck is my baby so id prefer it be done right

 

Sorry guys, but I fell asleep after my last post. Sounds like you got it worked out Matty. Might as well do a full transmission fluid change, new radiator and 2x flush with Zerex Pink Coolant, new OEM pump and timing belt, and anything else while you are in there.

Do it all so you don’t have to mess with it again. She is your baby.

 

I'll agree, a gallon of ATF, 2 gallons of Zerex, and 2 gallons of distilled water are cheap insurance to make sure you're ready to go.
