This thing is a Joke...Your better off to use a 2 Liter Coke Bottle.

I went through 3 before i finally found one that didn't leak from the heat crimp.(why did i try that many i don't know) Connector will not snap on the bottle. min/max level Writing on the bottle looks like my 2 year old used a sharpie.

Advance auto should be ashamed to sell this junk. spend the 80 at the dealer for a new one..or stock up on antifreeze and triple A Miles.

Comments about Dorman - OE Solutions Non-Pressurized Coolant Reservoir:

Several of these tanks have failed for me over the past few years. They always seem to start leaking on the bottom near a seam. The current part cracked just under the cap. Very poor quality part which results in $15 worth of coolant spilled every time the part is replaced. I've had to replace this part about 6 times in the past three years.

Comments about Dorman - OE Solutions Non-Pressurized Coolant Reservoir:

Replaced the original twice and both units have leaked after a few months. Poor quality parts. The proper coolant for a Passat isn't cheap and I've been through 4 bottles of the stuff.

    Comments about Dorman - OE Solutions Non-Pressurized Coolant Reservoir:

    I'm now ready to change out my fourth reservoir tank. All previous tanks have cracked (after about 9 to 12 months) around the bonded seam or the coolant ports. Not a bad buy if you don't mind changing them out.

        Wiring harness does not "click" to connect. will most likely fall out and get the warning again, but only have to pull 3 screws to plug back in.
        Otherwise, easy to install. 3 screws and 2 hose clamps.
