Where is the thermostat of Honda Odyssey in 2007?
Most automobile thermostats are installed at the upper water outlet of the engine.
The thermostat must be kept in good technical condition, otherwise it will seriously affect the normal work of the engine. If the thermostat main valve is opened too late, it will lead to overheating of the engine; If the main valve is opened too early, the engine warm-up time is too short and the engine temperature is too low.
There is no thermostat on the car water tank, but it is installed in the water pipe leading to the water tank on the cylinder head.
The thermostat is in the water pipe leading to the water tank on the cylinder head, and there is a small water pipe connected to the water pump next to the thermostat. There is a child's hand-sized cavity next to the valve cover, on the belt side, where it is connected with the water pipe of the water tank.
The thermostat automatically adjusts the amount of water entering the radiator according to the temperature of cooling water, which ensures that the engine works in a suitable temperature range and can save energy. Because the engine consumes a lot of fuel at low temperature, it is harmful to the car, and it is easy to cause carbon deposition, which brings a series of problems.
In general, when the engine is cold-started, the working temperature is very low, which can quickly heat up. At this time, through the adjustment of the thermostat (the main valve of the thermostat is closed), antifreeze is pumped into the water distribution pipe by the liquid pump, and antifreeze does not flow through the radiator. At this time, it is a small cycle. When the temperature of antifreeze reaches 87 degrees, the thermostat valve opens, antifreeze begins to flow through the radiator, and the cooling system enters a large cycle.
