Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 50 000 km (30,000 miles) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL® (silicate-free) coolant in the vehicle. Checking Coolant Cooling System (Intercooler) The 6.2L LS9 supercharged V8 engine has an intercooler cooling system. See Engine Compartment Overview on page 6-14 for location of the intercooler. The intercooler cooling system has a special procedure for draining and adding coolant. Because this procedure is difficult, see your dealer/retailer for service if the intercooler is low on coolant. The procedure can also be found in the service manual. To purchase a service manual, see Service Publications Ordering Information on page 8-17. 1. Verify that the engine and intercooler are no longer hot. 2. Place a cloth to absorb possible coolant loss under the driver's side bleeder valve (A). 3. Loosen, but do not completely unscrew the bleeder valve to check for coolant in the system. 4. Tighten the bleeder valve if there is coolant flowing out of the bleeder valve. 5. If there is no coolant flowing out of the bleeder valve, there could be a leak in the system. Tighten the bleeder valve and contact your dealer/retailer for service. 6-35
