In the event that engine temperature is shooting off the charts, you need to to inspect your Buick Gran Sport water pump for rough spots. Operated via a belt, the water pump streams coolant using centrifugal force all over the engine block for optimum cooling effects. If there's insufficient air getting inside the grille, your automobile will probably overheat and the cab will not be properly aired out.
You'll know your Buick Gran Sport water pump is about to fail if you pick up that unmistakable squeak that tells you it demands maintenance and repair. The pump's weep hole is sealed by a gasket, that is why once this is loose, coolant will definitely leak out. When the pump's bearing, gasket, or the pump itself conks out, you'd better stay away from taking your car out for a spin till the busted part is replaced (unless you want to risk engine overheating). To prevent the engine from heating up, it is advisable that you fix the busted water pump gasket or upgrade the entire unit for your own good. For stress-free fitting and superb functionality, get a first-class aftermarket pump that's specifically built for your automobile's cooling system.
