Temp sensor port threads were damaged on arrival. Mishimoto is helping to fix the situation. These things happen so I'm happy to say Mishimoto is handling the issue and taking care of it. Changing review to 5 stars.

This is hands down, easily the best radiator I've ever seen. The quality is outstanding, and it's shockingly light for something that's so well-built. Cooling performance is excellent: In my E36 I installed this, the Mishimoto MMTS-E36-92 62 Degree Racing Thermostat, the matching Mishimoto silicone hoses, and filled it with a 50-50 blend of distilled water and OEM BMW coolant, with one bottle of Red Line Water Wetter. Even running with a fan delete, it still tends to run one notch down on the thermometer from the centerline. If you've had cooling system issues with your BMW (and who hasn't) it's a great feeling to see that kind of thermal efficiency registering on your gauges. I should also point out that I'm living in Florida, where the heat is insane, and this radiator has absolutely no problems keeping my engine cool and running smooth, even with no fan. One feature I also liked a lot is the drain plug on this radiator has an integrated magnet to help pull out any metal dust or debris in your coolant mix, similar to the oil pan plugs that Mishimoto produces.

On the customer service side, Mishimoto also delivers. I was surprised to learn that not only does the part have a lifetime warranty, but that warranty also covers accident/collision damage. Meaning that if you wreck your car, Mishimoto will replace your busted radiator with a brand new one if you provide them with your receipt and accident report along with pictures of the damage. I've never even heard of a company willing to go to those lengths to support their product. Plus their web site has a ton of great info, including an excellent video showing the full installation process from start to finish.

E36s are infamous for their issues with the cooling system. The plastic components in the OEM parts degrade over time and can lead to a lot of frustration and headaches. It's true that an OEM radiator (or a comparable knock-off) is going to be cheaper, but it's also true that you get what you pay for. If you've ever been stuck on the side of the road with an overheated engine, then you know how much of a hassle it can be when those parts start failing. For the little bit of investment that this radiator requires, you can be done with those issues for the lifetime of your vehicle, and that is well worth the price of entry. Spend the extra buck, and treat your engine right. You'll be glad you did.

This is a great radiator. You can see tons of reviews on cooling quality, and it's as good as everyone says. So I'm going to review e30 fitment. You may have heard that this fits e30s, and yes it does! Good fit on my later model 325i.

I bought this for my 1990 325i. Perfect fit in terms of getting it into the car. I had one small issue with the two upper left hose outlets. You can see in the pictures that it's a tight fit. I absolutely could not get my hoses on the outlets. I could get one hose on, either the top or bottom, but there was not enough room to get a second on

Keep in mind these are E30 hoses not E36 which might be different. Also worth mentioning I have HPS silicon hoses, you might avoid this problem with rubber OEM hoses or Mishimoto silicon hoses.

I saw no reason to return it for this small issue, so I bent the upper hose outlet a very slight amount away from the lower outlet. I then flattened that lower outlet lip a small amount. I then trimmed the lower, larger silicon hose just a bit on the top to help. It really doesn't take much, so don't let this scare you off.

You may need to alter your plastic upper radiator mounts. I've got MTC mounts, fitment may vary. They're a bit too tall to fit with the radiator. You can fix this with a dremel, grinding or cutting will do it. Fits fine in the lower mounts.

I would buy again. Good quality welds too.

The radiator fit right in place on our 99 M3. Fit like a glove, easy to install - did it myself Been installed and operating for a month with zero problems. The polished aluminum finish looks great in the car - cooling performance is excellent.

Things to consider:
- Inlet and outlet tubes are polished. The hoses fit almost too easily requiring that the hoses get tightened more than you might think.
- You will need 6mm bolts to reattach the fan shroud, factory pins wont work.
- If you have a factory external trany cooler, you will need 6mm bolts to reattach as the factory screws wont work
- Take the opportunity to change the water pump, all hoses, belts, and stat if you've not already done so.

Definitely would buy again!!

This radiator fits really good into my e36 welds are excellent it's been in a month now and I'm very happy with it. However one drawback is that the upper radiator hose inlet is to close to the other smaller hose. Makes getting them on with the clamps very difficult. It they could've given a 1/4" it would be better
