welcome to the forum. when you changed engine did you bleed the coolant system? did you check the timing, did you tune the engine up? was the ecu reset if needed ? Did you do a compression check of the engine? Is the engine you put in the identical to the one that you changed.

what he said ^^^^^^ not all engine are the same meaning how they were used or if they were beaten on.... if you catch my drift

Thankx 4 da info
