Gasket part number needed - Thermo housing BUT water pump was the main leak

[Freddy1333]

Hi folks

I've search high and low on this forum and the Toyota 100 series parts illustrations for the gasket that goes where circled in red. I can't find it anywhere. Anyone got it?

TIA.

Thread 'Paper gasket between Water Inlet Housing and Water Pump?'

May 26, 2021

I can't find any mention of a paper gasket potentially installed between the LC100 water inlet housing and the water pump anywhere, so I'm throwing a "fish hook" out there to see if anybody else has run into this, and to hear from those of you who have already successfully made this repair. When I removed my old water inlet housing last night in order to replace it with a new one, I was surprised to find what appears to be a paper gasket between the water inlet housing and the water pump (see pic of water pump with paper gasket, as well as original water inlet housing with corroded FIPG...

OK...........but isn't item 16323C the O ring for the circular connection to the upper left?

Your red circle is around the rectangular port, which from the thread I linked, is FIPG. But yes, the o-ring is for the inlet.

Thanks TM. I dunno what FIPG stands for but I now see: FIPG (103, IIRC) only, with new o-ring on the pipe.

So a paper one is the replacement I guess.

FIPG - formed in place gasket - silicone sealant no doubt.

Well, it wasn't that gasket but the water pump. Coolant was dripping from the rear of the AC compressor, the oil cooler and filter, as it had been a week ago. Trying to pinpoint the source of the leak is somewhat a fraught endeavour as there's so much other stuff in the way. Anyhow, after removing the fan hub and tensioner, the plastic covers thereabout, the cam belt tensioner after setting the timing marks in their correct spots then removing the timing belt idler just below and to the left of the water pump, coolant could be seen leaking from the water pump drain hole - which faces rearward. Here it is circled in red on a new aftermarket pump. The a/market pump that's leaking is only 3.5 years old, so I'll be fitting a genuine Toyota replacement.

A bit of a mongrel job isn't it?!
