What Happens When a Ford Focus Thermostat Gasket Breaks Down?
The thermostat is probably one of the most important but least talked about part in the car. For the engine to cool down, the thermostat regulates the amount and rate of the coolant that passes from the radiator into the engine. On the other hand, the thermostat also prevents fluid flow when the engine needs to warm up to operating temperature. To keep the engine in the best temperatures, the thermostat must remain functional all the time. But with some defects and problems, the thermostat can jam or freeze up, causing excessive internal pressure that can blow up the gasket. Once there's a breach in the thermostat, it won't be able to control the temperature, making it harder for your car to remain operational. Here are some of the cautionary indicators when this gasket has already failed.
Engine that won't warm up
The complete counterpart of overheating, a cold engine is caused by a thermostat that is stuck in an open position due to a messed up gasket. A thermostat opens only when the engine has already reached a certain operating temperature so it could administer the coolant. If the engine is still well below the operating temperature, the thermostat must not let any coolant in so that the engine will burn the fuel efficiently. However, if a thermostat is stuck in the open position, the coolant flows into an engine, which leads to inadequate engine warming. This causes performance and fuel efficiency problems.
Erratic temperature readings
A defective thermostat gasket won't let the thermostat determine the right engine temperature will sway open and close unexpectedly. Once this happens, the whole cooling process will be rendered useless as the radiator is prevented from functioning well.
Leaks can be found near a blown thermostat gasket once it already fails. The thermostat is housed in a small open groove in the intake manifold where the upper radiator hose is attached. The thermostat gasket, which serves as a seal between the space in the middle of the thermostat and the manifold will leak and cause the coolant and some fluids to leak onto the engine manifold.
Flailing engine performance
By drastically altering an engine's operating temperature, a failed thermostat will mess up the combustion process resulting to a drop in performance. An engine that runs too cold or too hot will not run properly. It must be regulated at all times. Without the thermostat gasket, this won't be possible.
