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...
But if the heater core is leaking (or a hose connection to the heater core is leaking), coolant will be seeping out of the bottom of the HVAC unit and dripping on the floor inside the passenger compartment. Look for stains or wet spots on the bottom of the plastic HVAC case, or on ...
Now that fluids are drained, remove coolant hoses to and from the radiator in the front as well as the heater core in back. You also need to disconnect the automatic transmission hoses or lines that run from transmission to the radiator for cooling purposes. And assuming your power steering...
Leaks in the cooling system can lead to a loss of coolant, which in turn causes the engine to overheat. Common areas for leaks include radiator hoses, the radiator itself, the water pump, and the heater core. Even a small leak can have a significant impact on the cooling system’s effe...
the radiator or coolant reservoir and enables air pressure to be pumped into the system including the engine block, cylinder heads, coolant hoses, heater core and radiator. This pressure test simulates the engine getting hot and expanding the coolant which, in turn, will help you find the ...
or overflow reservoir cap. Hold it there for a few minutes and check to make sure nothing is leaking coolant. Replace the cap when you’re done. Warm the car up once more with the heater controls set to its hottest, most open setting to make sure nothing’s gurgling, and congratulations...

Common repairs required to correct overheating are: • Waterpump replacement• Radiator repair or replacement• Coolant flush• Thermostat replacement• Engine oil top-up or change• Coolant hose replacement Have you experienced any cooling nightmares? Are there any other causes of overheating ...
How the coolant circulates A typical water-cooling system with an engine-driven fan: note the bypass hose taking off hot coolant for the heater. The pressure cap on the expansion tank has a spring-loaded valve which opens above a certain pressure. A water-cooled cooling system A water-...
