Chevy Express Mystery Coolant Loss Fix

You need to look over your coolant expansion tank if you have a mystery coolant loss. The old style tanks loose coolant as you bounce down the road or even from backing into your driveway. The coolant overflow hose drips in front of your radiator and makes it look like your lower rad hose is leaking. reservoir expansion low Chevrolet Savana GMC diy how to 1500 2500 3500 2003 through 2019
Yes, the Dorman tank says it is a wiper reservoir...but obviously it is not.

Thank you for this explanation. This mystery loss of coolant has bugged me for years!

[@vinnybeedle1728]

Haha I looked this video up trying to figure out where the other end of the coolant overflow hose plugs into. Egg on my face. You’ve helped but probably not how you expected. Thanks!

[@frankchavez1893]

Lol I’m was trying to figure that out too, I even call me mechanic

[@richardkistner5549]

Thank you so much saved me a of aggravation on the mystery coolant leak.

[@MudFinder85]

I love your battery disconnect.

[@alvaromorales7123]

Good work man. Thank you. If it wasnt for you id prob replace my radiator again.

I have this mystery coolant loss on my 2006 Savana. Mechanic suspected busted head gasket. Hope this is my problem which is not very likely cuz mine lose coolant quite fast.

[@lonniemorrison2987]

I ordered the one you listed for my 1996 gmc savana. It doesnt look the same

[@ultrasounddjs_laultradiscoteka]

How much coolant does the new reservoir have? I have doubts about the brand it comes with. I have a 2016 4.8 express.

[@rehab4everybody]

But why would the loss started anyway?

[@Loligop5]

I was replacing my battery and noticed the hose connected to coolant reservoir was not connected to anything. Is this normal?

[@SteveRivett]

There will be one hose that just hangs down. That is the final overflow.

[@AngelPerez-vl7et]

Will it work to just cap off overflow ?

[@SteveRivett]

no, that would stop the system from working correctly and probably lead to overheating

[@itsshadybradybaby]

Wait so do you fill the radiator as well as fill the reservoir to the fill line. Or just fill the reservoir?
