Charles Fleming uses Lucas Power Steering Stop Leak for 1986 Chevy Cavalier

My 1986 Chevy Cavalier developed a leaky rack and pinion and I was losing about a quart of fluid every 2-3 days. I had to be very mindful of where I parked because of the puddle the leak would create. Several mechanics told me that it would be very expensive to repair the problem, and aftera time I got tired of adding fluid. So I just drove with out the power steering working at all. This was okay except for close quarters, such as shopping center parking lots.

A few weeks ago I happened to see an ad for Lucas Power Steering Stop Leak on a NASCAR brodcast and it prompted me to go shop for a bottle. I added it per the label directionsand the leak stopped almost immediately. The power steeringworks perfectly and the pavement beneath the vehicle is dry as a bone.

Because of how effectivethe Power Steering Stop Leak was, I will now try the Transmission Fix.
