ZR-1 Preventive Maintenance

 

 Attention to these items can help avoid the nearly inevitable problems that can occur if the maintenance is deferred for a very long period of time

 

·        Oil change and lubricate the front suspension. $37.50 plus oil and filter. Preference for a particular oil and filter can be fulfilled.

 

·           Power flush the brake fluid. DOT 3 fluid is recommended for street driving. For racing, match the type of fluid that is in use. For fresh racing preparations, Motul 600 DOT 4 fluid is recommended. This should be performed annually. $85 with DOT 3 fluid.

 

·           Flush the engine cooling system. Remove the thermostat and 100% drain and refill with OE type coolant. Remove the overflow bottle and clean the inside. Texaco coolant is recommended. This should be performed at 2 year intervals. $195.

 

·           Flush the clutch hydraulic system. The GM specialty fluid is utilized. This should be performed every 2 years.  $40.

 

·           Replace the transmission lubricant. The GM specialty fluid is recommended for street driving. If another specialized fluid is in use, it is matched. For racing, Castrol RS synthetic 10W-60 is recommended. This should be performed at 20K miles intervals for street driving, annually for racing.  $58. with GM lubricant. $70. with Castrol lubricant.

 

·           Replace the rear axle lubricant. We use Amsoil SVG 75W-90 synthetic lubricant. We add the Amsoil limited slip clutch friction modifier additive. Perform this service after the gear set has completed the first 2,000 miles. Then after 100,000 miles. Perform annually for racing.  $59.

 

·           Flush the power steering fluid. Use the GM specialty fluid. For racing, Red Line fluid is recommended. This should be performed at 5 year intervals, every 2 years for racing. '90-'91, $42. with the GM fluid. '92-'95, $52 with the GM semi-synthetic specialty fluid.

 

·           Tighten the oil pan bolts. This will extend the life of the gasket. Loose bolts contribute to the deterioration of the gasket. About half of the bolts are easy to access. They should be tightened at oil change intervals or once a year. All of the bolts should be tightened every two years. $7.50, tighten the accessible bolts. $75.00, tighten all of the bolts.
