Ive found my leak , just under the supercharger is a L shape black hose , seem hard to the touch, has no clamps on it an about 3 inches, i dont know how they installed it with no clampls tho , but mine leaks at hi speeds , having it replaced Monday, try looking there
The radiator on a 1999 Pontiac Grand Prix is flushed by draining the coolant, filling the system with water, adding a liquid flush to the system, and running it for a few minutes. The system is then drained, flushed with fresh water, and refilled with coolant.
You don't have a cap on the radiator. The cap is located directly on the coolant bottle
