ADDING & CHANGING ENGINE COOLANT CONTINUED
7. Once the engine has been shut down, squeeze the coolant hose above the transaxle repeatedly for a while
and watch for air bubbles to enter the coolant exchange tank.
8. Add more coolant as you are able to coax air bubbl es out of the coolant hose.
9. Repeat this startup / shutdown procedure as many ti mes as necessary until the bubbles cease, and the
upper hose is hot to the touch.

At some point in this process, the engine will “burp”, a nd the coolant gauge will begin to read properly. When
you are certain that this has occurred:
10. Release the pressure
VERY SLOWLY
at the tank.
11. Fill the tank again to the center seam level.
12. Check the copper air bleed fitting at the radiator to be sure the radiator is full.
13. Tighten everything up.
14. Run the engine until the fan turns on, off, then on again.
15. Switch off engine and allow it to cool completely.
16. Fill the tank to its proper level for the last ti me.

For vehicles with GM engines, the aftercooler fill locat ion is accessed by moving the seats to their forward mos t
position. In the center of the engine bulkhead is a tr iangular cover secured by Philips head screws. Removing
these screws reveals a semi-transparent port with a thre aded cap.


NOTE: Honda engines do not require an aftercooler coolant .

AIR FILTER REMOVAL & INSTALLATION
For vehicles with Honda engines, or GM engines with corrugated intakes, follow these directions:

To service the K&N air filter, the rear airbox cover m ust be removed. Remove the four 1/4 turn fasteners
holding the airbox cover to the engine cover and remo ve the body panel. Remove the three fasteners securing
the intake snorkel assembly, and you will find the air filter under it. The intake snorkel should rotate forward
within the roll bar to allow you access to the filter. Reverse this procedure to reinstall the air filter noti ng that the
K&N only fits in the snorkel one way.

A-ARM ADJUSTMENT
A-Arm adjustments are made with the double threaded "adjustment thimbles" (see photograph) which are
located on both the front and rear upper A-arms for u se in adjusting wheel camber. The same mechanism can
be found at the rear lower A-arm for toe adjustment . The adjustment thimbles are secured with lock nuts whi ch
must be re-tightened after any adjustments are made. The vehicle must be re-aligned after any camber
adjustment is made.
