Is 170 or 180 thermostat better?
A 180-degree thermostat is better for engine efficiency—aka better fuel mileage and decreased emissions. A 160-degree thermostat is designed to maintain a lower engine operating temperature, which tends to make a little bit more horsepower and torque.
What is a 170 thermostat?
With SPD Performance 170 degree performance thermostats, you get consistent engine cooling and increased horsepower by reducing engine temperature. You’ll also obtain more precise metering of water throughout your engine—as well as a long product life, since the thermostats are made from stainless steel.
Is a 160 thermostat too cold?
You should be fine with just the 160. You dont need to drill it. It will run alot cooler with it in anyways. No it is not too cold, the engine can still get to closed loop in winter.
Why is there 2 thermostats on a Duramax?
Their purpose is more for aerodynamics than engine cooling. The dual thermostat system was designed to accomplish the same temperature control under different load conditions. Instead of manipulation of the air side of the radiator, the coolant flow to the radiator is varied.
Will a colder thermostat increase power?
If you hang around car guys long enough, you will hear that a colder thermostat will help you make more power. However, a low-temp thermostat by itself does not make power. In some circumstances, a colder thermostat can help the engine make more power. But it’s not the lower temps that do it.
What temp should a small block Chevy run?
180-200 is a good range for carbed motors, 190-210 for EFI motors. If you run too cold, you get worse fuel efficiency, your motor oil becomes acidic due to not vaporizing the stuff out that needs to be vaporized, and your exhaust system may not last as long due to increased condensation.
Will a lower thermostat help overheating?
A low-temp thermostat gives the cooling system a head start. This will help to prevent Engine Detonation and overheating.
Does a cooler engine run better?
Performance vehicles move parts even quicker, from engine internals, to transmission gears, to differentials, only making components hotter. Cooling temperatures throughout the drivetrain will not only keep a car running longer, but will potentially help it run quicker.
Does a diesel engine need a thermostat?
Ultimately, the thermostat(s) and radiator in any diesel engine must work together to maintain the proper temperature range for the engine. Having a basic understanding of how the thermostat works, it’s clear what an important component it is when it comes to cooling system service.
Does a Duramax have 2 thermostats?
Today I learned my 2002 Duramax has two-yes-two cooling thermostats! They reside beside each other and use “O” rings to seal the housing to the block.
What degree thermostat should I use in my car?
Most experts agree that your engine should run between 195 degrees and 220 degrees. In ideal situations, your needle will maintain a posture right in the middle of your gauge.
