How to Service and Repair the Coolant Reservoir on Buick Regal?

You need to remove the cross vehicle brace as your first step when replacing the coolant recovery reservoir. Move the Coolant Reservoir hose clamp to the radiator overflow fitting and disconnect the hose from this fitting. Start by taking off the nuts from the shock tower studs until you remove the coolant recovery reservoir from its position between the lower retainer and shock tower studs while coolant drains into a clean container. For fitting the coolant recovery reservoir attach it to the lower retainer and shock tower studs before tightening nuts on the studs to 3.3 nm (29 inch lbs.).
