chalkyh 10 Posted November 5, 2020 Report Share Posted November 5, 2020 (edited) Yep, looks right. The lower one usually has a foil wrap / sleeve to protect from exhaust manifold heat. Pic is of my 96 VR which is standard and original, apart from a replacement top radiator hose. Edited November 5, 2020 by chalkyh correction Link to post Share on other sites
Vwmk3vr6 1 Posted November 5, 2020 Author Report Share Posted November 5, 2020 Does it even matter wich way the heater hoses go ?? Since they go in one way and come out another? Link to post Share on other sites
Harry-vr6 31 Posted November 12, 2020 Report Share Posted November 12, 2020 Im sure it matters as water will flow out one pipe to go in and the other flows out from the matrix so it circulates. I could be wrong Link to post Share on other sites
Vwmk3vr6 1 Posted November 16, 2020 Author Report Share Posted November 16, 2020 So i put the 160f back in and now fan comes on cools down engine and turns off like it should 👍but now it takes like 10-15 min to get to 160f 20-30 minutes to get up to middle of temp gauge or fans to come on .

Vwmk3vr6 1 Posted November 16, 2020 Author Report Share Posted November 16, 2020 Would a low fan switch fix this if i pit back in the 180f thermostat?thinking fans come on sooner so car can coll a bite to turn off ? Idk stumped . Link to post Share on other sites
