Default Any experience with the ECS cooling system refresh / Nissens Radiator?

Looking at doing the cooling system refresh this winter, and the "assembled by ECS" kits are on sale right now. The stage 3 (everything) kit includes a Nissens radiator, does anyone have experience with this one? I've read complaints about every brand, OE, Koyo, CSF, etc., but nothing specifically about Nissens.

I've also heard the expansion tank hose and water pipe connecting line should be replaced as well. Accurate? Anything else?

I didn't bother replacing the expansion tank and hose at 140k as they looked great. I have 173k now and they look the same, though I'm thinking of doing them in the near-ish future.

I would just go BMW on everything (WP/sensors/thermo/gaskets/coolant) except the radiator, which is made by OEM Modine for BMW. It works & it's not that expensive compared to BMW branded one. I wouldn't go OEM or aftermarket on anything except maybe silicone hoses if you want.

Nissen is a very reputable brand, however.

Lastly, I never like those "assembled kits". I always do better in quality and price, piecing it together myself, but I suppose the kit is good enough for those that aren't super clued in on what exact parts to get. Up to you, but that's my

Yeah, I second Tbone on going BMW on everything except maybe hoses and getting better kit/pricing if it is "assembled by {fill in YOUR name}". Does require a bit extra time and effort to piece things together yourself.

Don't have experience with Nissens but taking out an unused CSF (in diff thread) due to poor fitment and feedback that no improvement in cooling even for track over original.

Good find.

For M3, use dropdown under "Options", which adds $250 to the kit.

Default Re: Any experience with the ECS cooling system refresh / Nissens Radiator?

I called ECS and had them upcharge me for an OE water pump on the stage two kit. some of the basic stuff like belts, hoses, thermo, etc don't need to be OE but the WP I thought was worth paying for. I also got a deal on an OE radiator because the one in the kit was backordered for a week or something.

My ECS orders recently have been ridiculous.

I bought the radiator here a few weeks ago (modine), its even cheaper today. I didn't need a whole kit as most of it was already replaced by the PO, but 250 from getbmwparts is super cheap. great deal there.

Husker had the OE radiator for $240 when I purchased mine a few months ago. That was the cheapest I was able to find either OEM Modine or OE BMW.
