7MGE - Stuck with changing Head Gasket???

Bill UK · 07-24-2006, 07:00 PM

The correct name for that hose connection is Water BY-Pass Pipe. The socket size is 32mm (six flats), I made the mistake in ordering just one part number from Toyota without realising there are 3 parts to order. I refitted my head and waited for the remaining parts to arrive, I had a problem gaining access to tighten the nut up due to the bulkhead in the way. I resolved the problem by grinding down the 32mm socket but even then it was a tight squeeze.

Part numbers 90401-22004 Bolt Union 1 off,

90405-17005 Water By-Pass Pipe 1 off,

90430-22008 Gaskets 2 off,

These are old part numbers but Toyota should be able to identify them.

Hope this helps Bill UK
