Download • Loosen the lug nuts on the passenger side front wheel. • Raise the passenger side front of vehicle and secure with a jack/safety stand. • Remove the passenger side wheel and the plastic wheel well shroud in front of the crank pulley. • Loosen the crankshaft pulley bolt, but do not remove yet. – Manual Transmission: Have a helper put car into 5th gear and hold the brake pedal firmly, the bolt is very tight and will require significant force to loosen. – Automatic Transmission: Follow the crank pulley removal procedure/s specified in the factory manual. • Loosen the accessory belts and remove them. • Remove the power steering belt by unbolting the upper motor mount, this provides a gap to slip the belt thru. • Remove the original crankshaft pulley (be aware that the key in the crank may fall out, just reinstall in crankshaft before installing the new pulley). • Install the Unorthodox Racing crank pulley; lightly coat the inner bore of the new crank pulley with anti-seize compound and tighten crank pulley bolt, see torque specification below. Reverse the unbolting of crank pulley procedure for crankshaft pulley bolt re-torquing. Make sure the crank snout edge has no burrs, if no burrs are present pulley will slip on easily and seat properly. Do not force pulley onto crankshaft, as damage to both will occur voiding the warranty. In the rare case that a pulley is tight clean crank snout (as they can get slightly rusty) with emery cloth until pulley slides on as stated. • Install the new accessory belt, see the necessary new belt size below. • Re-install the remaining components in the reverse order. • Tighten the new accessory belt to the factory tension specification. • The maximum HP gains from the pulley/s can be expected within 5-7 days of driving, once the computer has recalibrated fully and taken advantage of the engines lighter rotational weight.
