Jason: some 2.1 WTB's have a heat exchanger, i.e. a combination of water
cooler and oil cooler, located between the oil filter and the engine block.
the oil filter has to be removed, then the shaft had a nut (aboaut 21 or 22
mm) to hold the cooler against the block. There a re 2 water lines that need
to be removed to get the whole unit out, replace the o-ring, and replace the
oil filter. Good luck. Armando
