These coolants will typically say 50/50 or pre-mixed on the front of the coolant bottle. Removing the coolant reservoir cap on a warm engine could cause the cap to fly off at a high rate of speed and fluid to spray out of the reservoir. Always wear safety goggles when working on...
Wait for the engine to cool. Drain the coolant from the radiator tap, or from the bottom hose, until it is below the level of the thermostat housing. If the hosing does not lift off easily, tap it free gently with a piece of wood, taking care not to damage the housing. Drain it...
Electrolysis within the radiator can lead to nasty sediment building an insulating layer around the coolant hosing leading to a lack of coolant flow and heat transfer. The hoses can also begin to crack due to the amount of heat cycles they have undergone, contracting and expanding until the ma...
Inspect and Replace your Car's Hoses What you can't see, can hurt you! That's what our engineers discovered during four years of extensive field-testing. In these tests, they identified the primary cause of coolant hose failure as an electrochemical attack on the rubber tube compound in th...
Replace the thermostat when changing a radiator. Flush the cooling system and install new coolant to protect gaskets and internal engine parts. Replace upper and lower radiator hoses. Inspect the cooling fan operation. Inspect and remove debris such as plastic bags in front of the front grill ar...
The unit's compressor system, which forces the coolant through the coil system, is driven by a capacitor-type motor. Other basic parts of the cooling/defrosting system include switches, thermostats, heaters, condensers, and fans. A do-it-yourselfer can test and replace many of these refrigerat...
Hoses -- Cracks, pinholes or splits in a radiator hose or heater hose will leak coolant. A hose leak will usually send a stream of hot coolant spraying out of the hose. A corroded hose connection or a loose or damaged hose clamp may also allow coolant to leak from the end of a ...
Again, refer to your owner’s manual if you can’t find it. 5. Check the Coolant Level in the Reservoir Look at the high and low (MAX and MIN) indicators on the side of the reservoir and check if the radiator fluid is between those two marks. 6. Inspect the Radiator Fluid You ...
A radiator or cooling system pressure test is useful when locating a coolant leak or a blown head gasket. This tool attaches to the top or the radiator or coolant reservoir and enables air pressure to be pumped into the system including the engine block, cylinder heads, coolant hoses, ...
All modern automotive engines are liquid-cooled, and the cooling system is essential to keep these engines from overheating. Radiator hoses carry coolant, or antifreeze, between the engine and radiator. Over time, a radiator hose is... READ...
