Description of ACDelco 20697S Professional Molded Coolant

Has a heat and ozone resistant cover to increase the life of the hose. Comes with a protective sleeve to help duplicate GM OE designs for proper fit and function. Made of re-engineered materials to resist vacuum collapse and also reduce the need for internal springs in many applications. Installs without buckling, bending out of shape, or straining at the connection for easy installation. Inside diameters ranges from 1?4 in to 1 in to fit different types of vehicles.

Terrible performance, avoid this product

This coolant hose failed miserably during my automotive tests. It was poorly designed and caused me more headaches than I had anticipated. The only positive thing I can say about it is that it was easy to install .As my tests showed, this hose is definitely not up to professional-level standards and I would strongly recommend going with a different brand for performance and durability..

Pros
  • Easy installation
Cons
  • Poor performance

Correct hose for 2007 E90 335i

The hose is a direct OEM replacement for a 2007 E90 335i and is sealed at the connections. with o-rings included and installed. Note that a hose installed on a smaller faucet near the radiator end of this hose may also need a new o-ring to seal properly after removing and reinstalling. I have used one of my spare o-rings (thanks to Harbor Freight) to ensure a leak-free seal.

Pros
  • Inner diameters vary from 1"-4" to 1" for different vehicle types
Cons
  • So far so good
