I heard it was only for 4.6L's, guess not since the application section on summit says it can be used with 4.0 motor. I never understood why not since aren't the hoses the same?

Anyway, anybody with a 4.0L done this?
Pics? I think it will look nice under the hood.

 

The coolant tanks are exactly the same whether it is a 4.6 or 4.0 so it will fit.

 

Do you know if the stock cap can be used?

 

Yes the stock cap can be used, and as JimC said it works on the 4.0 just fine.

 

Done it. I use a moroso tank. But i'm a v8 now. Same tank connections (two hoses).

 

awesome... now i just have to find a deal on ebay or something!

what about this one?

 

that will fit - there isn't any difference between the V6 and V8 when it comes to the tank. They both use the same part, it mounts the same way.
