winterset Posted August 22, 2014 Report Share Posted August 22, 2014 (edited) I wanted to change the coolant on my '96 Deville. Its been 4 years since the last time i changed it. I took out the airbox, and i couldn't turn the drain (at the bottom on the drivers side radiator). I took a mismatch 1/4 drive bit socket from the bottom of my toolbox, used my dremmel, and made a slit in the front, and placed the bit on the drain, lined up the slit, and unracheted the plastic drain off. I got 2 gallons out. Filled it with 1 gallon of distilled, and 1 gallon of GM approved Dexcool. The prestone dexcool was $17.99 a gallon! Ouch Then i made another round of turkey basting the power steering fluid out, and filled it with fresh blue ps fluid. I think all the fluids in the car are less than 6 months old now. I decided not to put the baars stop leak in yet. It took 2 cooling cycles to let me put in the full 2 gallons into the surge tank. I am good for another 4 years on the coolant and by that time the car will be 23 years old!!
