Thermostat with lower setting.
Does anyone know what happens if a thermostat is installed in the SVX with a lower setting? I know that a thermostat with a lower setting is not available but I still would like to know.
Does the cooling system build corrosion? Does the gas mileage go down? Will the transmission not get warm enough in the winter? Does it hurt the engine? Would the engine be slower? The transmission would run cooler 20F deg cooler with a 20F deg cooler thermostat. |

A few effects - engine would not warm up as quickly - you would not get heat from the heating system as quickly
gas mileage should suffer trans would not warm as quickly - if you don't have an external cooler. I don't see any effect after the car warms up, as either thermostat should be fully open then |

Gas mileage would suffer. Emissions would worsen. Oil contamination is greater from blow-by, resulting in earlier engine wear.
Question is why lower it? Because you think it would be the easy and inexspensive way to lower the tranny temp? It doesn't quite work that way. That's kinda like killing the sheep for its wool. Beav |

Hey Beav,
The SVX has the thermostat on the outlet of the radiator. Is this where most cars have the thermostat? The blow-by is higher when the engine is cold. That is good to know. Another reason to get the engine warmed up on a cold day. |

A lot of imports, and some domestics, have their t'stats located on the return. I don't see any advantage and it usually ends up up creating a more complex system. It usually makes it more difficult to change the 'stat also.....grrr....

Do you mean because it's on the bottom of the block and the whole system has to be drained?

Huh? Who said anything about draining? Ya lost me...

We are NOT going to be lost.
You say the "stat" is hard to change when it is on the outlet of the radiator. Why? I was thinking because the whole system has to be drained to change it. The "stat" on the SVX is on the bottom of the water pump, on the bottom of the engine, at the end of the lower radiator hose. Okay? |

Sorry, maybe I was thinking of something else, no prob. Anyway, thermostats mounted on the upper portion of the engine are generally easier to change. The plumbing is usually simpler too.

I think the piston warms up a lot faster than the block. The piston has a small mass compared to the block and can heat up faster. So there should be less clearance between a hot piston and a colder block. |

The heat causes the block to expand in all directions - inwards as well as outwards. Thus the cylinder diameters tighten up also.
