![]() The radiator fans seems to kick on and off just fine (when parked with AC on they cycle on and off periodically). Engine coolant temp as measure via the OBD app is never above 195 even when working hard, inverter coolant temp reads 20-23 (not sure of the units?). For the next week, check your coolant level frequently (with a cold engine), to be sure that there is no ongoing leak that requires regular. Use a 50/50 coolant-and-water mix, as specified in your owner’s manual. Simply top up your coolant to the Max or Full level when the engine is cold. The coolant levels in both the engine reservoir and inverter reservoir are at or just above the L level. Solution: This is potentially an easy fix. We've never had the red triangle or check engine light when this happens and it drives normally - only the coolant light on and then off again after a few minutes. My wife said she heard gurgling sounds near the inverter coolant, but the engine coolant temp looked fine when measured via the iPhone app and I don't see any obvious signs of overheating or leaking fluids. Now three months later, the light comes on again and then goes off on a short drive coming up the hill. No problems for the next few months, including a 400 mile road trip during which I monitored coolant temp with a bluetooth OBD scanner and iPhone app, and everything looked fine (coolant never passed 195F). ![]() So I returned to the mechanic, they replaced the radiator cap, pressure tested the cooling system and said it all looked fine to them. After a couple weeks, the light came on again and I noticed the level was back to L and there was some coolant that looked like it squirted out the top of the overflow reservoir. If this light comes on, its essential to take action to avoid severe damage to the engine. This could be due to a leak, low coolant levels, or a problem with the water pump. A couple months later, same thing happened, and I noted the engine coolant was a tad below the L level in the reservoir, so I topped off with fresh coolant all the way up to H. The Chevrolet engine coolant warning light is a signal that there is an issue with the engine cooling system. It's already been to the mechanic twice: the first time they said everything looked fine, but I asked them to replace the engine and inverter coolant since we were at 94k miles and the interval for those was 100k. Mazda cars also have a blue coolant light, just like Subaru. It’s a built-in feature to alert you that the engine needs to warm up. That is a normal occurrence and indicates that the engine is cold. Have the cooling system flushed and refilled with Honda antifreeze/coolant as soon as possible.Ok, we have a coolant light that comes on briefly every few months, always when driving up a steep hill (which we do a lot since we live on one). When the car starts, a blue coolant light illuminates. Continued use of any non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail. Check that it is a high quality coolant recommended for aluminum engines. If Honda antifreeze/coolant is not available, you may use another major brand of non-silicate coolant as a temporary replacement. If your vehicle is consistently subjected to temperatures below this, the concentration of antifreeze in the coolant should be increased. Genuine Honda engine coolant is a 50/50 mixture of antifreeze and water that can withstand freezing at temperatures as low as about -31☏ (-35☌). I have had several new cars before and never needed to add coolant before at such and early stage. Removing the radiator cap while the engine is hot can cause the coolant to spray out, seriously scalding you.Īlways let the engine and radiator cool down before removing the radiator cap. So this morning my coolant warning light comes on. If it is completely empty, also check the coolant level in the radiator. We recommend you check the engine coolant level every time you refuel. Put the radiator cap back on, and tighten it fully. ![]() ![]() The coolant level should be up to the base of the filler neck. Push down and turn the radiator cap counter-clockwise to remove it. Turn the radiator cap 1/8 turn counter-clockwise and relieve any pressure in the cooling system. Do not add any straight antifreeze or water. Make sure the engine and radiator are cool. This coolant is premixed with 50% antifreeze and 50% water. Specified coolant: Honda Long Life Antifreeze/Coolant Type 2
