Project E46 M3: Part 16 – Koyorad radiator installation


Here’s a close-up of the driver-side end tank, looking at it from the bottom.

Here’s a look at the passenger side from same angle. The unit has very nice welds throughout, and Koyorad did well with the fittings.

Both hose fittings feature provisions for the factory hoses, which have a clamping mechanism and two O-rings, eliminating the need for traditional hose clamps. These work well and are faster to work with when removing and reinstalling hoses.

The driver side looks just as clean. All in all, this is a really nice looking radiator.
