Engine radiator OEM BMW or OEM Toyota

I have a 2008 e90 335xi FBO with 197k miles and I am still on my original BMW radiator. If the stock original BMW stamped one works well... why experiment?

I can't believe your Tercel blew a rad. That was the most bulletproof car I have ever owned. It made me a life long toyota car owner

I replaced the aging radiator in December. It went smoothly, everything came apart and went back together as the Toyota Gods intended.

I had an older BMW myself (E36) and if you want reliability you'll need aftermarket (improved) radiator, radiator hoses and water pump.

I did change a radiator on my Previa few years back. It's more of a maintenance thing (if you ask me). Any car of that age will most likely have a bad radiator/ or clogged up radiator.

plastic radiator ends tend to crack and leak on the 4.4's. make sure you get an aluminum upgrade.

BMW N51 engine, SULEV radiator, these cars came with a sensor that sticks to the side of the radiator for emissions compliance. Can't even get it aftermarket anymore (last time I checked) new radiator without the sensor is like $150, with the sensor is close to $800, and no you cannot use the old sensor, if you try sticking the old sensor to a new radiator it won't recognize it and it will trigger the check engine light.

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.
