Check the radiator and coolant hoses along their entire length. Replace any hoses that are cracked, torn, or showing signs of aging. Cracks are easier to spot if you pinch the hose (see fig. 1.9).
Pay attention to the clamps that secure the hoses to the fittings of the cooling system. Clamps that are too tight can cause the hose to rupture or puncture, resulting in leaks in the cooling system.
Inspect all hoses and hose connection surfaces for leaks. If any leaking problems are found, replace that component or gasket.
Check the expansion tank cap seal for damage. Keep in mind that coolant loss can be caused by an expansion tank cap that is not screwed on properly or is not fully screwed on.
Loss of coolant and/or engine oil, as well as clouds of white steam coming out of the exhaust pipe, indicate that the cylinder head gasket has blown.
Install the upper engine cover.
Install the lower engine compartment splash shield.
