I paid to have my FJ40 motor rebuilt. Today I was driving down the freeway when all of a sudden I lost all my coolant. Turns out a freeze plug pooped out and I was able to recover it. The plug is stamped "EP 43 1 15/16" I thought it odd that a generally metric motor has a 1 15/16ths inch freeze plug. Do any of you know if this is normal or did the guy that I had rebuild my motor use the wrong freeze plug?
thanks.
thanks.
