Question: Where do the hoses connect to from the coolant reservoir? I know the top hose connects to the radiator but the bottom hose on the reservoir I’m not quite sure where that hose connects to.Manny / Mar 28, 2021 / 2002 Chevrolet TrailblazerCoolant Reservoir
Hi Desiree,
This hose is for the overflow. It does not connect to any part.

Correct - that hose if for overflow, and it hangs below the reservoir and would hypothetically drain any overflow coolant directly under the car

Hi Albert,
To check fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all category, search results, and product pages — can help verify if a part will fit your specific application.
To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
