Research the douse and antifreeze levels in your Impreza to prevent Very cold or overheating.
The engine on your Subaru Impreza generates expressive heat when in convenience. To prevent it from overheating and suffering damage, the coolant manner pumps a combination of dilute and antifreeze completed the radiator and encompassing the engine to chill it. Trial the coolant regularly to dash off undeniable that the levels are high rise Sufficiently, and that it contains the prerrogative percentage of flood and antifreeze. It should encompass a 50/50 alloy, prototype to prevent Very cold in winter and Hot in summer.
4. Drain coolant from the radiator if the system is full, but the antifreeze tester indicates the mixture is off. Raise the vehicle and support it on jack stands, then place a large container under the drain tube attached to the bottom of the radiator.
Fix the atramentous metal radiator (ethical latest the front grill) and the translucent plastic coolant reservoir dispassionate to the condign of it. Ajar the plastic cap on the coolant reservoir and test the fluid common, which should be at the borderline pronounced "Filled."
2. Remove the radiator cap. Subsume the tube of an antifreeze tester in the radiator and squeeze the bulb to allure coolant into the tester's Hospital ward. Recite the results using the manufacturer's directions, which Testament vary between testers.
3. Add a mixture of 50 percent distilled water and 50 percent antifreeze with an anti-rust agent to the reservoir if the level is below the full mark and the antifreeze levels test as normal. Add straight antifreeze if the antifreeze levels test low; add distilled water if the antifreeze level tests high. Start the engine and run it for a few minutes, then allow it to cool and use the antifreeze tester again to confirm that the antifreeze level is correct.
Instructions
1. Accessible the hood. Loosen the wing nut on the bottom corner of the radiator with a pair of pliers to open the drain plug.5. Tighten the wing nut to shut the drain plug when the coolant has drained out. Pour the drained coolant into a resealable plastic container and clean up any spills, then dispose of it as household hazardous waste. Fill the radiator slowly with a mixture of 50 percent water and 50 percent antifreeze.
6. Fill the coolant reservoir to the "Full" mark. Run the engine for a few minutes, turn it off and allow it to cool. Check the coolant level and add more coolant to the reservoir if necessary. Repeat, adding more coolant as needed, until the level remains at the "Full" mark.
