FIPG (Form in place gasket).
FIPG 103 is for oil (like oil pan).
FIPG 1282B is for coolant (like water inlet). Aisin has a smaller tube, that's equivalent, listed in their T-belt kits. Aisin AB120781 FIPG.
Using the wrong FIPG, may have chemical reaction with coolant. Which "may" damage bushing of water pump. Which "may" resulting in reduce life of water pump.
Absolutely do not use FIPG on O-rings or in place of O-ring. Doing so results on coolant pocketing in pockets created by FIPG. The trapped coolant will than become acidic, eating into metal pitting it.
Here's example of ones I've found FIPG used on O-ring:
After cleaning out FIPG, honing and polishing. Deeper pits, still remain. These pits will trap coolant and continue eating water bypass joints' aluminum.
The old O-ring was coated in, wrongly so, with FIPG, trapping coolant in pockets.
Note: Do not use excessive amount of FIPG on water inlet. Excess, may break away and flow into oil cooler, blocking it.
After cleaning pitting remained. This will like be a leaker. It to will trap coolant in pits.
Hi guys,
Does anyone have the part number, for the O-ring's. I went on partsouq, and the one sitting behind the waterpump I can't find the right diagram, probably have to dig deep into the toyota manual.
For the Waterpump side, does anyone have this part number in red? I didn't buy a timing belt change kit, I bought every part individually for the challenge.... so need find this O-ring.

I also see I need one more O-ring that is 9676 135 035 for the water housing inlet.
I already got the Thermostat gasket.
I see I will also need to get some Toyota 103 FIPG to make a seal on the water housing inlet as well after removing it... I was wondering if Permatex Ultra Grey will suffice too as I have that and FIPG is expensive.....
If you guys see I'm missing any other O-rings and stuff lemme know....

When Partsouq has "REFER To Fig 16-03". This is pointing you to another diagram (1603 radiator & water outlet) which may be on same
category page (here's 07LX) like engine or another of same vehicle like electrical.
Tips to save time and parts:
For a starter/S.A.I service. You do not need to remove the water inlet. Nor the water bypass joints, front or rear. Nor the water cross over pipe O-ring.
You almost always need:
- The long S.A.I. hose. (06-07 only
- The starter single wire housing connector 90980-11400. (98-07)
If you remove water inlet. You'll need:
Large O-ring
FIPG 12182B.
If you remove water bypass rear. You'll need it's two gasket.
Plus the S.A.I. No.1 & No.2 switches gaskets. I do not remove either bypass unless leaking. (06-07 only)
You do not need to remove, the water cross over pipe. It will partially block, one of the four S.A.I pumps securing nut/studs. Simply place a 12mm socket on the nut. Than attach a slim 12"x3/8" extension to the socket which is on the nut.
Tip:
To install/remove nuts and bolts, that are deep in confined space and not possible to reach with fingers. Place a piece of electrical tape (vinyl) across open end of socket. Then press nut/bolt-head into tape-socket. The tape will stretch and bind the nut/bolt-head in socket. Another method is to use forceps to place/grab nut/bolt into/out of place.
