Hello,
Just took off my water pump. I have a paper gasket for the replacement water pump. I looked at the block to scrape off the old gasket and there is none! This is a 2002 LC. There is a very fancy O-ring. I called the Dealer and they have no idea about an O-ring there. The Facto manual and Alldata show a paper gasket. Here's a PIC of the O-ring.

How should I handle this? I would like to replace the O-ring and that's it. I worry about putting the paper on top of the O-ring. How come the dealer and their mechanics have no idea what I am talking about? That's a Mystery?

That's pretty interesting. My LX FSM also has the gasket listed.

I believe the O-ring you are seeing is actually Hi-temp sealant.
Toyota calls it FIPG (Form In Place Gasket): Seal Packing Part No. 08826–00100

Since you said that, I went out to feel it a little more. Then I got up the courage to lift it. So I peeled some back, and you are right, it is some type of form a gasket that is "beaded" onto an indented ledge. That's the most precise "squirt gasket" i've ever seen! Answers my question though, pull it out and paper gasket it. Would you use RTV + the paper gasket?

Thanx!

Tough call but I would use exactly what was already in there as it has held up this long.

Personally, I'd go with the Toyota FIPG I listed. Check around though because prices seem to vary from $20-$75. Not sure if it comes in different sizes or what. Toyota specifies to use a small 2-3mm bead of the stuff.

I have 0.5 engine builds under my belt (and it was an old Datsun engine) so take what I say with a grain of salt.

Where did you find that reference for how to do it. The FSM shows the gasket.

In the FSM (Page CO-8), take a look at the water inlet/outlet housing that attaches to the water pump. It also uses the groove and FIPG sealant.

Also, if you have access to the FSM for the 1UZFE, it also specifies the same seal for the water pump. If need be I can type it word for word.

Hi,
I'm not questioning you, just trying to figure out why I didn't find it.
 
No, I didn't think you were questioning me but if you can't find, I can type it. Basically it says, clean old packing material FIPG with a razor blade. Use non-residue solvent. Apply FIPG with nozzle cut to 2-3mm opening. Part must be assembled within 5 minutes, otherwise the material must be removed and reapplied.

But you know, this got me thinking. Perhaps the FIPG is the old way and the gasket is the revised way to do it. I checked the 2005 parts diagram and they also show a gasket. Hmmm.

Hey,
That gasket material requires everything to be planed pretty flat and precise. It was thin. I've built some bug motors and Porsche 911 motors, so I'm acquainted with precision surfaces, but I may go with the paper and some RTV for Waterpumps on it.

Thanx for your help!

This post is super old but I'm just curious how this all turned out. In that picture posted the entire gasket is still stuck on the block. It's a metal gasket with 3 layers. I can clearly see it. So if anyone finds this post online from a google search, disregard the above conversation and peel that metal gasket off that appears to be part of the block. There's a rubber edge around the inner part of the gasket that actually melts to the block. Scrape down nice and smooth. Then wipe clean, and apply new metal gasket. I could see how this could be deceiving. I am just curious how the paper gasket maker fix turned out. Leaks?

I had to shake my head a few times because this has been a while! You are correct, it took me a while to figure out that there was a really nice gasket on there(Multi Layer). I believe my solution was to get an OEM gasket and not use the paper gasket.

Unfortuantely it's about time for another foray into this area. I need to do the timing belts again.
 
I've found numerous miss-points or wrong info in FSM, and issues that should be in scheduled maintenance that I' did not receive update(s) on from Toyota. That said I'm curious on this as well and I would use FIPG if:
IMHO: If when removing water pump, and if you have reason to believe it was factory installed. If FIPG is found then use again, along with gasket. In older cars (in the 1960 & 70's V8's) we always put "permatex gasket seal or form a seal" on everything and a sprayed sealer on head gaskets. The only exception was the exhaust.

The OP picture clearly show it is using FIPG, according to his statement.

So please clarify for me was it a rubber gasket or FIPG.

I can clarify. Only cause I just installed it. It's a tri layer metal gasket with a rubber seal around the inner edges. See mine? I had a couple bad leaks in it cause the rubber was so melted and shot, I had to scrape it off of the block and make it nice again. That's the only reason I resurfaced this thread. I just wanted to make sure a noob, like myself didn't google "water pump" and find confusing info. Cause there is a TON of info out there that has almost thrown me off course.
