Mishimoto MMRT-E36-92E Expansion Tank Compatible With BMW E36 3-Series 1992-1999 Silver

Amazing product! I have used this same product for 4 years now and would buy over and over again!

Best cooling system upgrade you can do!Super high quality, machining is perfect, and so is the welding! I haven't pressure tested yet, but like all Mishimoto upgrades I've done, I have full confidence it will work perfectly.Highly recommend their radiator and radiator hoses!

Heavy duty

Instructions leave a lot to be desired for, the hose coming off the side does not connect to anything and acts like an overflow squirting fluid to the ground through your engine bay (weird). "Dipstick" level checking device works well enough. The best thing I can say is that it is all metal which is a huge improvement over the original. Downside is there is no way to eyeball the level while it is hot, if you open the dipstick to check, well you would be a dipstick.

This unit is about an inch taller than OEM so it does not fit in the car. If hiu check my picture, it is supposed to be under that fan housing so the little black nub is in that hole. There's no way to affix this unit to my car. Mishimoto's description is a lie and this is not an OEM replacement.Pretty mad.

i bought this expansion tank for my 96’ 328i, the welds on this are freaking amazing! it’s lightweight and it feels like a very high quality part.

Looks nice, but expensive and IMHO let down by fit engineering.My E36 had a stock cooling system Plastic radiator/ Tank / mechanical fan. Radiator was seriously weeping at the tanks, decided to bite the bullet and upgrade to durable components. Was not originally planning to purchase the tank as my standard tank was not cracked and fairly new - BUT I snapped the overflow connector off when refitting so decided to upgradeMain issue I had with this tank was the fit between this tank and the fan shroud. You would think that as these are all designed to work together they would fit perfectly. NOT SO! the flare on bottom hose connector was TO BIG to fit though the bracket on the Mishimoto fan shroud!That is just DUMB, and unacceptable for the price this cost. Other issue I have is that the top mounting is not confidence inspiring. There just seems a little too much play between the bracket supplied with the shroud and the small nub on the tank. Once the bottom hose is on tight then its a little firmer but come-on Mishi - you can do better! Yes it can be fettled BUT for this sort of money should NOT need to be.The other issue I had was that this is was a real bear to fill and bleed properly. Much harder than the standard tank, which if not done properly can still be a bit of a pain. Not sure if its the internal design of the tank but they have done away with the standard bleed screw so there is not a good way for the air to escape as you fill. The only way I could get it to work was to jack up front very high and disconnect the small overflow hose from the radiator - that then released the trapped air.As to long term - only just completed and test driven so cannot report on that, but this setup should end the plastic torture once and for all. but IMHO is let down by the small things.

Looks sleek, works as expected.However, it's difficult to install into your car because it doesn't fit into any of the stock setup. It doesn't have clamps to fasten into, or anything to sit on. However, it will fit into the mishimoto fan shroud without issue. Basically, the guys at Mishimoto are trying to sell you a package of cooling parts by making them difficult to install unless you buy everything, so if you are a dumb consumer who doesn't like to think outside of the box, then it will be easier for you to shell out close to $1000 for parts so that everything will bolt in "the way it's supposed to."I had to fabricated some brackets to hold it.Also, the radiator cap is very difficult to install/remove. You have to put 30-50 pounds of downward pressure onto the cap to get it to turn past the hard stop that machined into the neck of the tank. I understand that it is designed like that to prevent unwanted opening, but it's excessive. I used a dremel to shave a little bit off of the neck of the tank and now the cap installs a little easier.All in all, a good purchase. But be prepared to do invest some man hours making it work.
