If a flowing sound can be heard (from the heater core in the cabin) repeat this process from step 17 on.

Save Like Dezlpwr Discussion starter 3 Thetwister007 said: My 2021 crosstrek from the factory was also on the low mark since I didn't want to void any warranties,I just told them to fill the engine coolant on the first oil change. Also, add coolant to the overflow reservoir until it reaches the "Full" line. If the coolant level has dropped add coolant until the level reaches the filler neck. Most likely because the horizontal design of Subaru engines keeps the head gaskets always submerged in coolant. Subaru does not want these additives to be used on their engines. This means that it does not contain Supplemental Coolant Additives. Be careful with the coolant temperature to avoid overheating the engine.ġ8) Stop the engine and wait until the engine coolant temperature lowers to at most 86 degrees F.ġ9) Open the radiator cap. The Subaru Super Coolant is an ASTM D-3306 anti freeze. Firefighters Because even cops need heroes. Close the air bleeder plug.ġ5) Re-attach the radiator and reservoir caps.ġ6) Start the engine and turn the heater on to the maximum hot position with the blower speed set to "LO."ġ7) Run the engine at 2000rpm until the radiator fan starts and stops. I had to have a quart drained and bottle of concentrate added to drop the freeze protection even more and I think it was almost 50 bucks to do that. Add coolant to the radiator until the fluid level reaches the radiator neck. If the coolant level has dropped, open the air bleeder plug in the heater hose. Spend no longer than 40 seconds completing this step.ġ3) Wait for an entire minute and then remove the radiator cap. Start the engine and race the engine 5 times to about 3000rpm.

Otherwise continue filling the radiator.ġ1) Fill the coolant overflow reservoir until the level reaches "Full."ġ2) Replace the radiator cap, and twist to seal it. If the level dropped, fill it back up to the filler neck.ġ0) Close the air bleeder plug once fluid starts to come out of it. Pentofrost A3 Coolant Pentofrost A3 is our first alternative to Subaru Super Coolant, which is a phosphate OAT, i.e. This motor oil provides outstanding quality and convenience. This Subaru engine oil is dexos1 Gen 2, API SN, and ILSAC GF-5 approved.

Running your car on older deteriorating antifreeze or coolant can cause acid buildup, scaling and reduced resistance to extreme temperatures. The longer you use coolant, the more its useful chemical properties break down. Performing routine maintenance on your vehicle’s cooling system will ultimately prolong the engine’s life. Youre also not supposed to run dexcool or dexclone coolants in there. Antifreeze also fends off rust and corrosion, helping to extend the life of water pumps, radiators and other cooling system components. Youre also supposed to add the Subaru coolant conditioner when you change coolant on that engine as it can be prone to external coolant dripping leak at the head gaskets. In the winter, the chemical formulas in antifreeze also prevent water and moisture from freezing, which can damage the cooling passages inside the engine and other components just as it would the pipes in your house. I is specifically formulated for Acura, Honda and Subaru vehicles and is suitable for hybrid & electric models.
