Before i drive i need to add to tank i park and leaks. The Saturn book says to only add 50/50 DEX-COOL coolant. I cannot find it any where. Is there any other kind of coolant i can put in? Please help.

Not without causing problems like gelling coolant and plugged systems. I would fix the leak, then while you have the coolant drained for that flush the system real good and re-fill with common green coolant. You will need to service the system more often but you can use common antifreeze.

Thank you and for this year of car coolant goes in the tank right? I cannot tell where it is leaking from. When i did check it was wet around the cap on the tank but i see drips from the middle front area.

You are correct. Leaks can be difficult. You can rent a pressure testing tool from many parts stores that can help. You fill the coolant up cold and put it under pressure, then look for the leak.

Then you look at every hose, radiator, water pump and coolant location for any sign of a leak.
