1JZ water pump housing to rad hose seal help

R33_JAY · 22nd December 2012, 06:54 PM

Hi all

Got a 1jz engined project nearly ready for mapping, need to put the top rad hose metal pipe, back onto the waterpump housing. Its connected by the little metal joiner, and has 2 rubber O ring seals that sit in the connector. Ive check all my local hardware stores, and when the o ring is fitted it either slips in the hole pretty easy with no real force, or the next size up is savagely tight and wont go in unles there is extreme pressure to fit it.

Went with the extreme option, got it in one end and its very tight, however it looks like the rubber seal is further in the housing in places which would suggest it has popped out the little O ring seats in the joiner.

What have you guys used to seal them? will the seal sat how it is do the job or am i likely to get a leak from it? Driving me nuts now

Thanks in advance for any help

Can you not try the original seals from Toyota?

thats what i thought straight away, contacted a very well known tuner parts supplying company who use toyota 1jz engine in their race car, and said the toyota ones are useless and dont seal right?!!!

Yeah, because Toyota usually fit dodgy seals to their engines

So what did they suggest in its place?

lol i know, i just trusted their experience and accepted what they said as truth. He said to try motor factors, did that and non of the o rings fit correctly. Tried hardware stores, and plumbers merchants. many had the same o ring box from silvertec.

Are they the same on the 2J?

Well I'm not sure how identical they are between the two engines but below is a pic of the same thing on the 2JZ engine.

The part number for the two o-rings (both the same part number) is 96761-24023. May be worth a try.

Actually not quite true, i've just checked the EPC for a 1JZ engine and they are the same part number o-ring.
