I just bought a 1990 Toyota Hiace diesel, 2.8L (I think). It's a
right hand drive Japan import with 107,000 km. 4WD auto. I've been
driving a 1991 gas Previa, which is great but expensive at todays gas
prices.

Is the motor and drive train the same as a forerunner or landcruiser?

What is the towing capacity? Any advice on how to add a trailer
hitch? Should I add a transmission cooler or is there a sufficient
one already installed?

The back bumper has a flat spot where I could just drill a hole and
bolt on a trailer ball, but it seems like sheet metal rather than
heavy steel. My boat and trailer are under 600 lbs. Comments?

Is there a way to reduce carbon buildup from the exhaust gas
recirculation system?

This looks like a good group. Thanks

Fred
