These instructions will be broken down into the four corners and named bracket of the oil cooler. The corners will be referred to as A, B, C and D as shown in the below picture.

 

Step 1

 

 

Install and tighten the -10ORB to -10AN fitting into the oil cooler in Corner B. Go ahead and tighten it all the way. There is no fitting for Corner D as the hose end threads directly into the cooler.

Step 2

 

Using a RUBBER isolator, mount Bracket A to the Corner A of the oil cooler. This should be installed in the front hole. Do not tighten at this point, keep all mounting hardware finger tight until final installation is complete.

Bracket A and Bracket B are very similar so don’t mix them up. Bracket A is slightly longer than Bracket B.

Step 3

 

 

Using a RUBBER isolator, mount Bracket B to the Corner B of the oil cooler in the front hole. Remember to only keep hand tight for now.

 

 

 

Step 4

 

 

Using an aluminum spacer (black shown in picture but part will be machined finish), mount Bracket C onto the front hole of Corner C on the oil cooler. Once again, keep finger tight only.

 

 

Step 5

 

 

Using an aluminum spacer, mount Bracket D onto the front hole of Corner D on the oil cooler. Once again, keep finger tight only.

 

 

 

If installing the optional power steering cooler, refer to steps 6 through 8. If not installing power steering cooler, proceed to step 9.

 

Step 6

To identify the power steering cooler brackets, refer to the picture below. Although the brackets look amost identical at first glance, they are not. Bracket 2 is angled upwards. Make sure they are installed in their respective locations or the power steering cooler will not install.

 

 

Step 6 Continued

 

 

Install Bracket 1 onto the rear hole of Corner A of the oil cooler. Take note of the orientation. The tap, should face upwards toward the front hole like shown in the above picture. Only install finger tight at this time.

 

 

 

 

Step 7

 

 

Install Bracket 2 onto the rear hole of Corner B of the oil cooler. Take note of the orientation. The tap, should face upwards toward the front hole like shown in the above picture and should have a slight angle upwards like shown in the below picture. Only install finger tight at this time.

 

 

 

Step 7 Continued

 

 

 

 

 

 

 

Step 8

Mount Power Steering Cooler to the power steering cooler brackets using nuts and bolts as shown in the pictures below. Only install finger tight for now.

 

  

 

 

 

Step 8 Continued

  

 

 

 

 

 

Step 9

Install the assembled oil cooler into the vehicle in front of the AC condenser as shown in the pictures below. Keep all harware finger tight.

 



 

Step 9 Continued

 



 

 


 

 

Step 10

 

 

Drain coolant and oil. Remove factory oil cooler and oil filter bracket (Naturally aspirated cars will not have an oil cooler). It’s recommended to remove intake manifold first to make these steps much easier. Note: AC compressor is not shown in picture.

Step 11

 

 

Install oil cooler bypass hose. Naturally Aspirated vehicles skip this step.

Step 12

 

 

Install oil filter union. Thread shorter side of the oil filter union into the block. Only tighten hand tight.

Step 13

 

 

Install the two ½ NPT to -10AN fittings into the thermostatic sandwich plate. Use a good thread sealant to prevent leaks.

Step 14

 

 

Install the sandwich plate onto the block. The AN fittings should be pointed down.

Tightening procedure: Lubricate contact face of sealing ring lightly with oil. Tighten plate/extension screw until seal contacts sealing face, then tighten further 3/4 turn.

Step 15

 

 

Attach oil cooler lines to bottom of sandwich plate. They should look like above, straight away from the block and route around the AC compressor (not in picture). Secure lines to the vehicle using some zip ties or cable holders (not supplied). Routing should go under frame rails and follow along AC line routing, as fits best. There may be factory plastic liners that may need to be trimmed or removed for the lines to run to the bumper area of the vehicle.

Step 16

 

 

Attach hoses to the oil cooler as shown above. Take care that the fitting that threads into corner D is carefully routed around the AC line that is very close to it. Feel free to position the oil cooler using the adjusting slots in the brackets to make it fit the best. After the lines have been attached, and secured to the vehicle in the most ideal routing possible, tighten all hardware on the oil cooler. Keep the power steering brackets finger tight until they have had their lines installed as well.

 

 

Step 17

 

 

Install oil filter directly onto the sandwich plate.

If installing the PHR Oil Filter Relocation Kit, refer to Step 17a.

Note: On 1997 and 1998 vehicles, the oil filter pressure switch must be relocated. The PHR Oil Filter Relocation Kit provides ports for relocating the switch or installing aftermarket oil pressure sensors, as well as being a good source for oil to feed a turbo on NA to Turbo Conversions.

 

 

Step 17a

 

 

Install PHR Oil Filter Relocation Kit as shown. Oil flow will go from “Out to In” and “In to Out”. By that, the oil will flow out of the block adapter from the “Out” port and flow into the oil filter mount through the “In” port. It will then flow through the filter, then out of the “Out” of the oil filter mount and into the “In” port on the block adapter.

 

 

 

Step 18

 

 

Attach power steering houses to the powe steering cooler. Then tighten all hardware on the power steering cooler bracket. Run one line to the power steering reservoir and one line to the steering rack upper port.

If using stainless line, use the M17x1.5 fitting to adapt to the power steering rack. The power steering reservoir needs to have a 6AN fitting in order to use the stainless line. The PHR billet power steering reservoir is perfect for this system.

If using rubber line, no adapters will be needed. Use the pushlock hose ends for the cooler side. The rubber lines will attach to existing lines on the steering rack and reservoir.

Secure all the lines and tighten all fittings. This completes the installation.
