Engine radiator OEM BMW or KOYORAD

I replaced it with a OEM style koyorad I found for $130 and corrected the radiator caps and my temps have been perfect all summer. It is a bitch to burp the coolant so I recommend buying the spill-free funnel.

E36 on factory, untouched cooling system replaced earlier this year. Date stamps on the radiator, hoses, thermostat housing all indicated they were never replaced.

The Koyorad full aluminum radiator is the one to have. Paired to your Hayden 698 since it doesn’t have a section to cool the trans fluid, however definitely worth it for durability as the next alternative over OEM replacement rad.

The first radiator at the dealer was a genuine BMW part# 17111436060. Mine has lasted well.

I bought a Koyorad radiator for my 2003 Toyota Sequoia and worked out perfect!

I refused to install anything but a koyorad

My all aluminum Koyorad radiator is a far superior unit than the factory original.

Replaced with original.

24 years is good for me.

The white tank has never been the issue for me, leaks are always in the radiator frame surrounding that tank. Somewhere at the bottom, probably where the lower hose goes. The plastic is brittle crap and it develops micro-fractures that become cracks over time.
