Hi Runnin on E,
My 4Runner is sitting in my garage with the intake off at the moment. I knew the starter was going to be tough but man! It's a real challenge. I've swapped 1997 FZJ80 labdcruiser motors faster than this!

The starter requires the water coolant bypass cast u piece above it to be removed (which requires two gaskets) in additoon to a water pipe that requires an o-ring, and EGR valve in the back gets removed! PAIN!

So I had to stop my wrenching sunday and order more parts.

These has to be ordered in addition to the above list:

water bypass gasket (qty 2) 16341-50020
EGR pass side vacuum hose 17340-50030
secondary air pump injection hose 17341-50180
hose off air switching valve 17342-50180
EGR pipe gasket (qty 2 +1 extra) 1737750010
replacement 3.5mm vacuum hose 90999-92003
water outlet pipe o-ring 96761-24019
Ø3.5 mm vacuum hose to swap old hoses under intake 90999-92003 (Qty 4 lengths)
