When adding engine coolant, use a 50/50 mixture of clean, drinkable water and engine coolant. Made to keep your vehicles engine running cool Designed to maintain proper cooling level and prevent overheating. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle. from the water pump to the engine block and the cylinder heads.Ī closed water thermostat returns the engine coolant to the water pump an open water thermostat allows the engine coolant to flow to the radiator.Įngine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components.from the lower radiator hose (8286) to the water pump.will not operate with the switch in the OFF position.operates only when the ignition switch is in the RUN position.replenishes the engine coolant to the system.provides air separation during operation.contains coolant expansion and system pressurization.controls the engine coolant temperature.water temperature indicator sender unit (10884).engine coolant temperature sensor (ECT sensor) (12A648).Hope this helps and good luckīad low coolant switch or still low on coolant. Also top off the coolant in the radiator while it is running. This should burp out any air pockets that may have happened when coolant was changed. In this video I cover all the symptoms of having air trapped inside your cooling system, including overheating, high operating temperature, no heat from your. Leave the cap off and let it run until engine warmed up. When and if you change your radiator cap, make sure the engine is cooled down, remove cap and start engine and turn heater to full blast, full heat. That way if it is overfilled or becomes overfilled it will slowly leak onto the ground. The one on the bottom comes from the radiator and the one on the top (possibly part of filler cap) runs down and is open to the ground. The expansion tank should have two hoses on it. It's easiest just to replace the cap because they are inexpensive and easy to replace (2-10 dollars). I would look at your radiator cap to see if any gunk or build up is on it, and check the rubber gaskets for cracks. The cap has another part to it that when the engine cools down and a partial vacuum is created in the cooling system a "valve" in the radiator cap opens and allows the coolant to be drawn back into the engine. The radiator cap allows the cooling system to build up pressure and by doing so increases the boiling point of the coolant, but when that pressure exceeds the caps rating the cap opens and the coolant goes to the expansion valve. Now when the engine cools down the pressure drops in the cooling system and the pressure drop (vacuum) pulls the coolant back into the engine via the radiator cap. The coolant then goes into the expansion tank. When the engine warms up the coolant gets hot, builds up pressure and opens up the radiator cap. What the expansion tank does is collect and return coolant to and from the engine. The water (coolant) in the expansion tank will rise and fall with the engine temperature.
