Partol Aluminum Coolant Flange Upgrade Kit Fits VW MK4 Golf Jetta GLI GTI TT 337 1.8T (Cooling Hose Flange+Coolant T-Fitting+Thermostat Housing Cover + Water Distribution Pipe)

You can see the quality if the cast is superb and give an amazing look to the engine bay. After installing this kit I am sure I will not need to replace these coolant flanges.

Good quality for the price. Internal castings are a bit rough, but a dremel tool cleaned it up. Much better than the original plastic pipe fittings.

As these are all-aluminum replacement parts for the original thermoplastic ones, I expect they will have a longer service life than the OEM's. What I like in particular, was the kit's coolant flange. It does not use an "O" ring, but rather a gasket and flange. After cleaning the mating surface to remove any grease or oil, I installed the flange using Permatex non-hardening sealant and got a coolant tight seal. Much happier with this as the original design was somewhat tentative on sealing. Overall quality of the kit was good.

the quality on these is incredibly low, and they contain cooling system destroying manufacturing debris and are very poorly cleaned from the molding process. do NOT install one without running a wire brush through it at minimum..

I recently had a coolant flange that’s was (plastic ) break on my 2001 Audi TT Quattro ALMOST caused major engine failure. I received this aluminum replacement coolant flange fit it was easy to install and it won’t break no more VERY PLEASED WITH THIS PRODUCT ! Highly recommended to the VW AND AUDI enthusiast’s

Perfect fitment finally an upgrade that was needed

Great value for the money. Will need some dremeling on the inside to trim the casting.

Ok
