2004 E46 320i manual with 116k miles. Bought it just over a year ago for \u00a32000 probably spent around \u00a31000 on it (radiator, air con, rocker cover gasket, oil sensor, boot switch, coil pack), not too bad for a 20 year old car I don\u2019t think. Only thing that doesn\u2019t work on it is the cruise control, it used to but recently stopped.

Pros: not too bad

Cons: cruise control stopped

Vehicle: BMW

Mileage: 116000 km

I bought the mishimoto rad and it works well, the main benefit to the mishimoto is that they have a no questions asked lifetime guarantee. I had to replace it after a year due to a leak and mishimoto replaced it completely free with very good customer service. So the rads might not be as good as CSF but my dealings with the company have been very positive.

Pros: lifetime guarantee, good customer service

Cons: not as good as CSF

I had a leak/split in the top of the radiator and bought a factory DENSO replacement part from Rock Auto with free shipping for my 2001 Camry that fit like a glove for $100.

Pros: factory replacement, perfect fit

Vehicle: Toyota Camry

Pros: OEM quality, no issues

Mileage: 48280 km

Leaks:

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

Overheating:

It started overheating while I was on I-95, and I managed to limp it to an off-ramp. It needed a new radiator, and that was the last straw for me.

Cons: overheating, needed replacement

Leaks:

I drove 200km to go camping, oil was ok when I left, drove 200km back and made it home fine. Then 2 days later when I tried to drive it again for the first time my radiator was pouring steam after 5km and it turns out she had leaked all the oil on the drive over the weekend which made it overhead and blew the radiator. The hot radiator expanded and cracked the plastic tank where they joined, once the engine cooled overnight that crack showed up and leaked ALL the coolant out and I had no idea. Had to replace the radiator but she's ok again now.

Cons: radiator blew, cracked plastic tank, leaked coolant

Vehicle: Subaru Forester

Mileage: 5 km
