Engine radiator OEM BMW or KOYORAD
I went with the Koyorad on mine. Everything fit perfectly, no modifications needed, which hasn't always been the case for me
Pros: perfect fit, no modifications
Ive had my car enter limp mode multiple times on a high 80 track days. Coolant temp would spike to the 3/4 marks. When I upgraded the radiator to a koyorad I never had issues again.
Pros: no more limp mode, stable coolant temp
I am here to say the Koyorad fits perfectly fine with Cobb’s charge pipe. The upper radiator hose had to be completely taken out to get the pass side fan installed but no trimming or cutting of fan shroud. The radiator looks amazing as well.
Pros: perfect fitment, amazing look
Experienced a full separation of the top (and possibly bottom) plastic from the aluminum portion - would leak about as fast as I could pour it in. Replaced with Koyorad A2807 from RockAuto.com for $104 plus tax and shipping. Nominal time to repair for a non-mechanic is probably 4-to-6 hours - call it a day project.
Pros: fixed severe leak, cost-effective
Vehicle:
Nissan
Mileage: 531082 km
Part number: A2807
got a Koyorad off Rock Auto for around $100 and slapped it in there. Runs like a champ. It is a pretty easy job if you're mechanically inclined.
Pros: runs like a champ, easy job
Vehicle:
Nissan
I've had a Koyorad in my 97 for 5 years now and it's been great.
Pros: great performance, 5 years durability
Vehicle:
Toyota 4runner
i recently put a koyorad in mine as well, the hoses at the bottom took me forever to work with but it was worth it
Pros: worth the effort
Cons: difficult hose installation
I got the thicker Koyorad and managed to get it to fit with some redneck engineering, but it was a squeeze.
Cons: difficult to fit with AC
I've replaced a radiator on a BMW 2018 3 Series with as little as 22k miles. This particular vehicle was leaking from the side tank of the rad, where the plastic is crimped to the aluminum. Nothing abnormal could be seen, just the crimp failed.
Cons: leaking from side tank
Vehicle:
BMW
Mileage: 35405 km
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.
Pros: new radiator available
Cons: expensive radiator with sensor
Vehicle:
BMW
