Driving Without A Thermostat
I need your opinions on this.
A friend told me that a thermostat in a car is not necessary for proper engine operation and that the thermostat is mainly there to provide heat for people in the car. He said that cooler engines run better, are more powerful, last a lot longer, and provides more protection for gaskets. When the thermostats on his cars go bad, he takes them out altogether and runs without one. If needed, he even hooks a portable electric heater in his vehicles to get heat in the winter. He loves his engines to run very cool. When I ride with him, the temperature gauge in his cars never even move past 'C'. What do you think of this? Would it be alright to take the thermostat out of my car and drive without one if mine ever goes bad? I drive a '91 Plymouth Sundance w/ 2.5l engine. |

Strictly speaking... your friend is right. However, there are some
negatives involved in removing the thermostat: 1.) Engine warm-up time is greatly increased (and may never reach proper operating temp in cold weather) causing fuel-rich operation for a longer time period. This can have negative effects on the engine as well as impacting gas milage. 2.) Computer controlled cars (like yours) may never go off fast-idle.

Aren't the exhaust , o2 , and catalytic systems designed to operate at
certain (hot) temperatures as well? Defintely not optimum. Older cars probably dont care too much, but newer ones sure do. (post 1970) |

Your friend must like stopping at the gas station, because without the
thermostat closing your car will get really crappy gas mileage. |

Any car that is computer controlled needs to run at a set temperature,
usually around 190 F to operate right. For starters, it will stay in warm up mode running really rich until the computer 'sees' a certain temperature on one of the sensors. This burns too much gas and can contaminate the oil with gas. Some vehicle will also overheat at higher speeds with no thermostat to restrict some of the flow. The coolant needs to be in the rad for a certain time to transfer heat away, too fast and it doesn't cool down. Most race cars use a flow restrictor sleeve in place of the t-stat if they run without it.

It works for Harley Davidsons In addition to that, if he has no family and no likelyhood of every having a girl friend, he could remove all the seats and mats, except the drivers seat of course. In addition to removing weight, he would then have space to start a small camp fire for heating and demisting, instead of having to use an electric heater as is friend apparently does. |

| Engine
| develops more power with cooler intake air. But not with lower coolant | temps. Ridiculous ; why then fit any radiator ? |
