Well I have put 3,000 miles on the AAZ so it was time for an oil change so I figured this would be the best time to attack the oil cooler swap.
I purchased the thermostatic sandwich plate from Summit per Andrew's recommendation.
I had the Volvo oil cooler from a trip to the pick and pull a few years back.
I went to Napa and had them fab some hydraulic lines. Using rubber hoses and clamps seemed a little too fragile to me.
I also ordered hoses to delete the coolant lines running to the stock cooler. I just ordered the hoses for a N/A motor.
The hose that runs from the cylinder head to the water pump is a little short, but it works.
Also the "crack pipe" on the N/A motor is smaller in diameter than the AAZ's. I swapped it back in so I would have one less hole to plug.
The coolant lines were the hardest part. This is largely due to the fact that I put the hoses on the engine when I was assembling it, and as a result the hose clamps were not oriented in a way that made them accessible in the car with the injection pump in place.
The next hiccup I ran into was that I needed to grab the shorter threaded shaft from a motor without the oil/water cooler. Luckily for me I still have my N/A motor handy.
What I removed is on the right. What went in its place is on the left. The hole in the center of the sandwich plate is larger in diameter than the stock cooler. This means you can't bolt it up with the stock threaded shaft and nut. You have to use their adaptor. This also meant a trip to the store to buy a 1-1/8" Deep Socket. Apparently their are still people not using the metric system.
So here it is in place with the hydraulic lines. The woman who helped me at napa did not have swivels for the male end, so that made installation a bit harder as these lines are very stiff, and will snap back and slap you in the face. Don't ask me how I know
Here is the other end of the lines. This photo is taken from the drivers side just in front of the wheel. The cooler is mounted underneath the battery. It has a little metal scoop on it to grab some of the air flowing under the car. We will see how well it works.
Here it is again from a lower
And looking down on it from the top.
I whimped out and took the air filter out of the rain tray and it is 5,000 times quieter. The piping is strapped to the firewall so it will stay in place
In the process I plumbed the hockey puck to the intake with some pricy silicone. I need to get this stuff fabricated when I am finally happy with the setup. I think it will stay this way until I upgrade the turbo. I have installed a new radiator a while back that has an integrated reservoir. This cleans up the bay a bit, and it does not leak like my old one did.
I relocated the fuel filter to the passenger side fender wall so I could have room for the intake.
I also installed the USRT linkage kit for the transmission which replaces all the steel balls and plastic sockets with Heim joints. It is marginally nicer, but it was a total PITA. It required a lot of cutting, drilling, and sanding not to mention I had to adjust the lengths of the rods about 20 times before I had 1st gear again.
Anyway next up is a slim radiator fan or two with an adjustable switch.
cheers.
