2002 3.4 runner engine into a 2002 Tundra

Hello,

I have a 2002 Tundra 3.4l 4x4 with a bad engine, I found a great running 3.4L engine from a 2002 4runner. Will this motor from the 4 runner have any issues in the tundra? Any things that make them different that I may need to know before doing the swap?


Thanks for any help!

Just keep the harness and sensors from the tundra and toss them in the 4runner engine. They’re the same. Only potential difference is the 4runner might not have the oil cooler on the block, but it can be swapped over

 

If you search Toyota's parts website for the "partial engine assembly" you can get a part number for the engine in your truck. You can then click on "what this fits" to see what else it was used in.



For my 2000, the engine part number is: 19000-62320

It is possible a 3.4 from a T100 would fit too, but there was something that changed between the 90s and 2000s and you'd probably want to check each part number one by one (block, piston, rods, crankshaft, etc) to see what it is.
