I should clarify - if your oil cooler is FUBAR, I'd swap *that* with a CSF or larger.

In my car, I've
Swapped the mechanical fan for electric -> Would recommend hands down, to avoid the risk of the mechanical fan exploding, and it gives lots of room to work on the front of the engine. Car used to overheat in traffic, doesn't with the old (tired) mechanical gone and swapped with SPAL.

Swapped the rad for Koyorad -> Would only recommend if you can get one at equal or lower cost to OE. I'm really happy with it, but the performance is about on par with OE.

Swapped the oil cooler with CSF -> Definitely the single largest improvement to track temps. Before I was consistently at dot or pushing toward red in coolant, and at the dot in oil temp, while this made it to where my coolant stays at just over 12:00 and oil usually under the dot.

Used silicone hoses -> The hoses are fine, but the fittings that attach to the rad were a total nightmare until I replaced the O-rings with Viton and silicone. I would go with OE or OE with silicone hoses, no aftermarket of any kind on the fittings.

While you're in there, you should probably replace the overflow tank and other assorted plastic bits, especially if your car has more than 75k

I love the electrical fan simply for ease of removal when working under the hood. Have had no issues with cooling on track so far.

OE hoses have not failed yet. I'd probably go silicone during a refresh.

Can you share the details on the part number, size and source of the viton o-rings? Thanks!

Standby..
I’ve filed an insurance claim bc bumper, radiator air duct, rad support, belly pan, aux fan, maybe water pump, radiator, AC condenser, and oil cooler are ****ed. That’s like $2k worth of parts.

If you find a way for insurance to cover maintenance work, please let the rest of us know haha

Insurance came back with a $3,800 repair estimate...
I've attached a list of what I will be ordering.

I'm gonna delete both fans and replace with one SPAL fan, install CSF oil cooler (OE has damaged fins), and get an OE radiator.

The silicon hoses that both ECS and BW sell come with OE/OEM fittings. Do you think I'll be fine with either of those?

A couple items to consider:

- Delete belly pan and order undertray/splitter?
- Delete brake ducts/brackets and order proper backing plates/hoses?

Sounds like you have a great plan! Personally, I am not a fan of 550 dollar oil coolers and instead run Setrab or similar, but understand the desire to have OE mounted solution for simplicity. Also consider running AN adapter fittings for stainless braided lines as well as an oil diverter valve delete?

The fittings I fought with were from BW, clearly made by Continental. They did great for several track days, mind you.. but the o-rings eventually wouldn't seal.

Based on images on ECS that don't show any grinding where there's usually a BMW logo, I'd go out on a limb and say they are not OE/ OEM

I'm not 100% sure if you can trash the front fan in you want to run AC, so I'd ask around on that one.

Don't forget O-rings for the cooler.

Sounds like you'll have a nicely refreshed track tool

Where did you find the high temp o-rings? Part number?
