I'm about the change the water pump and timing belt on my 1j motor before i do the swap. I'm new to the lex/toyo/1j world and I have searched. I was wondering if i can use the water pump with the clutch and fan from a 2jzge engine for the 1j. This is my 1j motor and I'm showing the pump pulley.

You can definitely use the 2jzgte water pump.

People that go na-t on the 2jzge motor are using the stock NA water pump and it works fine so I assume it should work fine on the 1jzgte motor as well, but I wouldn't put a high mileage pump on if the motor was out of the car, because it is a major ***** to get too really.

 

I dont plan on using my old water pump. But I do want to use the fan and clutch part of my old water pump. I just want to basically know if a new ge water pump with my old fan and clutch would bolt up and work fine for a 1jzgte motor. I also dont mind using a gte water pump. Mainly I want to know how I can use my old fan from my ge engine

 

You CAN use the old fan if you space it back toward the radiator a few mm, or trim the blades, but you need to use a GTE water pump.

 

You cant use a GE Water Pump on GTE block they are different. Yes u will need to space it out. GL

 

Thanks a lot guys.!!
