    Q:
    How to replace the thermostat in a cylinder head for Buick Century and Regal? Posted by Customer
    A:
    Remove any gasket or sealer with the thermostat from the cylinder head. Unbolt the water neck by draining the coolant system below the thermostat level when trying to replace it. The next step is to remove the water neck and thereby expose the thermostat. Thereafter, clean off all traces of remnants from both manifold and residual gasket material or sealer on water necks that mate. Installing it with its wax pellet downwards is a good idea. Besides, apply some sealant on both sides of the gasket then put it on block. Finally, hold it down using retainer bolts.

    Q:
    How should the new thermostat be installed for the 1989 Oldsmobile Cutlass? Posted by Customer
    A:
    Place a 1/3 inch bead of RTV or equivalent sealer around the sealing surface on the engine and place the thermostat into its recess. Immediately place the thermostat housing with sealer and a new gasket into position and torque-tighten the attaching bolts. Where applicable, install the TVS switch and vacuum hoses.
