• Q: How to replace the coolant reservoir on 2003 Buick Regal?

  A: To change the coolant recovery reservoir, try to reposition the radiator overflow fitting at the Coolant Reservoir hose clamp and remove the Coolant Reservoir hose from the fitting. Next, remove the nuts from the shock tower studs and take out the coolant recovery reservoir from the lower retainer and from the shock tower studs, draining the coolant in a clean container. For installation of the coolant recovery reservoir, would put it back on the lower retainer and shock tower studs and then install nuts on the studs, tighten them to 3.3 nm (29 inch lbs.). Lubricate the reservoir hose with clean water and route it to the radiator overflow neck fitting and install the Coolant Reservoir hose on the fitting that has the hose end flush with the radiator filler neck and the clamp squarely between the neck and the flare end of the fitting. Finally, move the Coolant Reservoir hose clamp to radiator overflow fitting and pour the coolant recovery reservoir to the right level.
