Chase Bays Oil Cooler Block Adapter - Toyota 1JZ | 2JZ



Chase Bays Oil Cooler Block Adapter - Toyota 1JZ | 2JZ

The Chase Bays Oil Cooler Delete Block Adapter was designed to remove the weak coolant assisted OE 1JZ | 2JZ oil cooler and replace it with a powerful external oil cooler. This is for just the extended stud, a kit with our Thermostatic Sandwich Adapter is available here: Chase Bays Oil Cooler Block Adapter Kit - Toyota 1JZ | 2JZ

The Chase Bays designed extended stud solves a big problem with other block adapters out there. Others just sell a universal hollow 3/4-16 threaded rod cut to length. Ours is designed and machined specifically for the 1JZ-GTE, 2JZ-GTE, and 2JZ-GE application.

A stud like this doesn't function like head studs, for example. With head studs you stage torque those down to high values. With something that functions as hand tight...more thought has to go into it. There have been numerous cases of these studs backing out to cause catastrophic engine failure. In our design process we add a "seat" for the stud. This allows it to be tightened completely and secured against itself and the block. We chose 6061 aluminum over steel since its strong enough for this application and it's lightweight. As always we anodized it UV-proof signature Chase Bays Semi-Gloss black with our logo laser etched in the side.
