With the engine running and in great shape it was time to add one more piece. A good deal came up on a used Cobalt kit that relocates the oil filter to the firewall and also adds an oil cooler. For a track car this is a very good idea as track days will have the engine winding in the upper rpm ranges all weekend long. Keeping the oil in a lower temperature range will allow it to last longer and do its job better.
First thing was to clean up the kit. I used Purple Power to de-grease the hoses and the oil cooler, especially in between the fins of the cooler.
Next was to figure out how best to mount everything. I found Cobalt’s instructions on-line and read through them. My kit had an additional spacer block to move the remote filter mount out from the firewall since there were ABS lines crossing in that area. I measured out from the fender edge the 9″ as instructed and drilled the three holes for the mount. Later I was to regret that.
Then I disconnected the hoses from the remote mount and the oil filter adapter. I was able to source a new o-ring for the oil filter adapter that replaces the oil filter in the stock location and mounted it. The directions have you remove the intake manifold brace so there was plenty of room to install and tighten. The brace went back on after the kit was completely installed.
With the adapter in place I ran the hose to the remote filter mount. It was then I discovered that I had to relocate the mount on the firewall to make clearance for the hose. More holes.
I had previously found a mounting spot in front of the radiator for the oil cooler and I took a piece of right angle aluminum and fabricated a mount. I bolted the cooler to the aluminum and used some nylon isolators at the mounting points.
The assembly was bolted up in front of the radiator and I ran the two hoses around the lower right side of the radiator having one lead up to the remote filter mount on the firewall.
Once again I discovered that I would have to adjust the mount’s placement on the firewall. Too many holes. I found some scrap 18 gauge steel and fabricated a good-sized backing plate to ensure that the mount had plenty to hold on to.
Now the hoses hooked up to the remote filter mount and had the proper clearance. Down below I ran the last hose from the oil cooler to the filter adapter on the engine block. A careful visual inspection made certain that the hoses would not be subject to chaffing and they were secured with nylon tie wraps.
The engine was started and the car put up in the air and checked for leaks. There were none. It was hard to believe.
When the engine was warmed up it was shut off and the oil was drained. Since this was a used kit it was best to flush out the system and put new oil in. A new K&N oil filter was screwed in and five and a half quarts of Castrol 10W-30 Synthetic with their “Titanium” was used. The engine was started again and checked for leaks. None. All was good.
I could now install the new front bumper cover.
