• Q: How to replace the coolant reservoir on 2003 Chevrolet Impala?

  A: Start the replacement of the coolant recovery reservoir by removing the cross vehicle brace. You need to move the hose clamp (Hose Clamp) into position. Before installation disconnect the reservoir hose from the radiator overflow neck then release the coolant recovery reservoir nuts (Nuts) from shock tower studs. Drain the coolant into a clean container when you remove the coolant recovery reservoir (Reservoir) from its lower retention points on shock tower studs. To install the coolant recovery reservoir (Reservoir) position it on lower retainer and shock tower studs before tightening its coolant recovery reservoir nuts (Nuts) on shock tower studs to 3.3 nm (29 inch lbs.). Clean water lubricates the reservoir hose before installation of the Coolant Reservoir hose (Hose) to the radiator overflow neck fitting. Secure the reservoir hose to the radiator overflow fitting on the radiator filler neck so the hose end sits flat against the radiator filler neck while using the clamp (Hose Clamp) which faces the 11 o'clock point. Install the cross-vehicle brace afterward while keeping the coolant recovery reservoir at its proper fill level.
