Having problems with your 1999 Saturn SL ?
Where is the radiator cap? How do I check the water??
The radiator has no cap-the system is pressurized at the coolant recovery tank, on the left side of the engine (facing it)-it has a screw on cap (15PSI)
If the cap is not along the top of the radiator then its sealed. Which means you only have that resevoir that you put water in
