Engine radiator MISHIMOTO or OEM BMW
I got a Mishimoto with zero issues and fitment was spot on
Pros: zero issues, spot on
And don't put the oem radiator in (it sucks). A mishimoto is 2/3 the price, will last longer (it's not made of plastic at the top -- that's why the oem ones fail) and it will actually keep your engine a little cooler.
Pros: lasts longer, keeps cooler
Cons: oem ones fail
Vehicle:
Subaru Impreza
If u get a mishimoto it won't break again
Pros: durable radiator
I like my Mishimoto one. But I have an Auto, and the only one they had for the Baja didn't have the cooler built in, so I had to run an external trans cooler. But it all went easy, even with that. Electric fans and catch tank bolted right up no problem
Pros: easy installation
Cons: external trans cooler needed
Vehicle:
Subaru
Exact thing happened to me last year. Replaced with a Mishimoto
Vehicle:
Honda S2000
It happened to me once at a night time. I just pulled over, stopped the engine and started again after several minutes and everything was OK.
Edit: After reading other's comments, I realized that mine also related to coolant system. Some time after this incident I replaced radiator because of a coolant leak. May be this warning is related to that.
Pros: Everything was OK
Cons: coolant leak
The crap-tastic mishimoto MMRAD-E36-92 that I use these days do come with a lifetime warranty and I send them photos of the leak and they just send me a replacement in a week or so. I have purchased 6 of them and replaced 2 under warranty. The "Z3" raditator won't fit as its too thick, but the Z3 IS and e36 so its confusing.
Pros: lifetime warranty, easy replacement
Cons: crap-tastic, pinhole leaks, poor welds, Z3 fitment issues
Vehicle:
BMW
Part number: MMRAD-E36-92
My mishimoto radiator sprung a leak after 1.5 years in my F150. So good luck.
Cons: sprung a leak
Vehicle:
Ford
My first non warranty repair on my B58 540 was a $3k radiator replacement. That was at about 60k miles.
Cons: expensive radiator replacement
Vehicle:
BMW
Mileage: 96560 km
Get a csf or koyorad. Mishimoto isn’t that great
Cons: not that great
