Oil Cooler x Thermo Fan – Day 8

It's all done!!

After cleaning up the engine bay, I spent most of Tuesday night putting everything back together. Was a pain in the ass and I scraped the shit out of hands and arms, sooooo many sharp edges along castings and hose clamps.

The end of Tuesday night.

Oil Cooler x Thermo Fan – Day 6

I was made aware this morning that the orientation of my oil cooler core was incorrect. Having both inlet/outlet located on the bottom causes air pockets to occur, and also very ineffecient cooling. The ideal way to mount the cooler core is to have it vertical with inlet at the bottom and outlet at the top. As oil enters the bottom and fills up the core, air is pushed out of the system.

So spent most of the morning making new brackets to re-mount the cooler core. Fortunately I didn't have to make any new braided hose, the existing ones were the correct lengths =)

New brackets made up.

All mounted up for a test fitting.

Also spent the morning prepping the relay/box. Two factory relays were removed and the rest were re-arranged to make some room for the new relays. All wires that won't be used were heat-shrinked and tucked away. Wires that are to be used were tagged for tomorrow.

Also finished up the Defi sensor wires and tidied it all up. You can also see the extra wire I ran for the fan controller temp sensor.


Oil Cooler x Thermo Fan – Day 5

Had a pretty late start on the S15 today, earlier in the morning we went to the East Coast Customs garage sale to pick up some parts and didn't get back until about midday.

All the oil cooler parts have now been removed to be cleaned inside and out. I made some markings on the braided hose, and this is where I'll be installing some protective spiral wrap. It will protect the hose from rubbing against anything. Anyway some photos of the complete oil cooler setup.

Oil Cooler x Thermo Fan – Day 4

Today I set out to install the oil cooler core plus make the rest of the braided hosing. I initially hated making braided hosing but I enjoy it now, got my technique down pat. Just wish I had some AN spanners to keep the fittings looking nice.

Before cutting your hose, wrap the cut area in electric tape. This keeps the metal braid from fraying and flying everywhere.

Oil Cooler x Thermo Fan – Day 3

bleeehhhhh more uni and business stuff today so couldn't get much done today either =(

I picked up my intake manifold from Clifton Engineering, had them drill and tap a thread for the temp sender for me. I wanted the fan controller temp sender to be as close as possible to the stock senders.

Then I got back home and finished laying down the wires for the Defi sensors and fan controller temp sender. Was also able to make up ONE braided hose, going from the oil filter block to the relocator. Was my first time making a braided hose, and I did not enjoy it at all.


Oil Cooler x Thermo Fan – Day 2

Wasn't much of a car day today, didn't get much done at all because I had some uni and COEM Audio stuff to attend to.

I went by Extreme Motorsports and Enzed to pick up some parts, and then dropped off my intake manifold at Clifton Engineering to get a hole tapped for the VDO temp sender. Most of my other parts were already ordered from Summit Racing in the US.

My efforts from today -

The remote oil filter block, shown with -10 fittings and rubber o-rings. The oil outlets were tapped with BSPT threads instead of NPT, so fancy anodised fittings weren't available.

Oil Cooler x Thermo Fan – Day 1

Beautiful day today, so had a mate over and started pulling apart the S15 =)

The front bar is being removed so I can mount the oil cooler in the corner under the headlights. Radiator is being removed so that the new Falcon AU thermo fans can be installed. The intake manifold is being removed because I want the temp sender for the Dakota Digital fan controller to be in the same spot as the factory temp sender. The intake manifold being off also makes it a lot easier to install the oil filter block. More info these parts in my next post.

Jacked the car up and drained all the coolant out of the system.
