Heater Union (Coolant Leak)

Bill UK · 05-11-2008, 10:50 AM

Bloody good write up Slader99, Toyota part #`s below. As you can see you need to order 4 items, the top and bottom gasket/washers have the same part # `s. Very hot in the UK today, need to get on with replacing my shocks. Will follow up with some more info of my experience with replacing that heat union later. Temperature must be around 74 ? F, At last summer has arrived in the UK, catch yer later.

Assuming you don't wreak your union bolt and union pipe, you will only have to replace the gasket washers part # 90430-22008.... If you are using silicon you might even be able to reuse them, but for the cost and potential effort saved it makes sense to replace them while you can.

Thanks for the props Bill, I just hope this helps someone out. It took me a long time to decide that I was gonna attack this with the head on engine in car, but rather than make some elaborate tool I decided to go with this socket hack.... Just one more custom toyota SST I guess
