WARNING: Risk of injury to skin and eyes from scalding coolant. Do not open cooling system unless temperature is below 90°C (194°F). Open cap slowly to release pressure. Store coolant in approved and appropriately marked container. Wear protective gloves, clothing and eye wear.
NOTE: Constant tension hose clamps are used on most vehicles. When removing or installing clamps use tools designed for servicing these types of clamps. A number or letter is stamped on the clamp. If replacement is required use only original equipment clamps with a matching letter or number.
NOTE: When removing the radiator, note the location of the rubber radiator-to-body air seals. These seals are used to prevent overheating and must remain in there original positions.

Do Not waste usable coolant. If solution is clean, drain into a clean container for reuse.
