What is the purpose of a coolant bypass valve?
Most engines have a small coolant bypass passage that permits some coolant to circulate within the cylinder block and head when the engine is cold and the thermostat is closed. This provides equal warming of the cylinders and prevents hot spots. When the engine warms up, the bypass must close or become restricted.Click to see…

Thereof, can you bypass a car thermostat?Please don’t bypass your thermostat. It controls coolant flow to your radiator. If you leave it open, your engine will take a really long time warming up, which wastes fuel, produces unnecessary pollution, and unnecessary wear and tear on the engine itself.Likewise, what does a thermostat bypass do? This design of thermostats uses a bypass system to speed engine warm up. When the engine is cool the thermostat is closed. As the engine warms up, the thermostat begins to open allowing coolant to pass through to the radiator. At the same time a lower poppet or bypass valve moves down to block the bypass canal. Keeping this in consideration, what does code p26b7 mean? light on with diagnostic trouble code (DTC) P26B7 stored in. the Powertrain Control Module (PCM) memory. This DTC indicates a fault is present with Coolant Bypass Solenoid C, located at the rear of the engine above the starter/ bell housing, and below the vacuum pump.What is a bypass tube?The heater bypass tube is a cooling system component found on many road going cars and trucks. It’s purpose is to serve as a cooling system passage that bypasses the thermostat, so that there is coolant flow even when the engine thermostat is closed.
