CSF7046 High Performance Radiator

So far had it for like 2 months and it’s working good keeping my temps lower

My CSF radiator recently started leaking. CSF has a 2 year warranty, which I have about 3 weeks left to claim. B2C Auto Parts first denied my request, saying the warranty is only 1 year. When i mentioned the manufacturer warranty, they told me to buy a new one and send them the original, and they would check with the manufacturer before providing a refund. However, I'm not getting the feeling they would indeed provide the warranty refund.. not to mention, what if I end up having a problem with the new one, they would do the same thing over again. Not the way to conduct business. I will also be in contact with the manufacturer and ask that they don't do business with this company in the future since they do not honorably represent the brands they are selling.

Replaced a leaking stock radiator on a 2008 BMW 335i E93. Engine bay ont his car is tight. This radiator is high quality but I had to cut off the nonsensical tabs on the back (see pics) and also dremel down plastic on the fan housing to get the fan to fit. There are no instructions on the box nor on CSF's website that I could find, only DIY's on the interwebs and, since I have an E93 with A/T, it differed from most of them. CSF has a good reputation so I expect it to last a long time.

Radiator has no separation between the lower "tank" and upper "tank" causing the car to run cold all the time. Car will not develop heat. This is due to bad design and CSF nor the retailer will take the radiator back or repair it. CSF will not return calls

I had this radiator for around 2 or 3 years now and I just noticed a leak where the core meets the end tanks. CSF will not warrant the part and it looks like i'll have to get the mishimoto one unfortunately. The radiator itself is extremely effective, dont listen to the other review where the guy says it creates condensation. Thats wrong, this radiator lowers temps 15-20 degrees, the condensation issue is usually dependent on the oil cooler and thermostat condition. Fitment of the radiator was ok but if you are running aftermarket inlets, its a tight fit between the belts and will almost certainly require a ziptie or bracket to keep the inlets off the belts.

Drastic temp drops. You won't see much difference though unless you drive it hard, have mods and need to avoid limp mode due to high temps
