THERMOSTAT - How Important

**city** · January 5th, 2006 11:02 AM

water starts to boil at 100degC...and it's actually evaporating........

thermostats should detect or activate prior boiling point

water coolant helps in delaying that rise in temp in engines

it's important you have thermostats installed...unless you don't mind replacing aux fans now and then.

Water starts to boil * 100 ºC when you are at see level, but when you are at high places like Baguio it starts to boil lower than 100 ºC

Termostat's main function is to bring the water/engine temp to optimal level as quickly as possible, beyond that, the radiator does the rest to keep the temp maintained to that level. Theoretically, you should have better fuel mileage with the thermostat with an efficient cooling system complimenting it of course.

The thermostat is located where the fluid leaves the engine. The plumbing around the thermostat sends the fluid back to the pump directly if the thermostat is closed. If it is open, the fluid goes through the radiator first and then back to the pump.

There is also a separate circuit for the heating system. This circuit takes fluid from the cylinder head and passes it through a heater core and then back to the pump. please check this link. hth

Sir XTO,

who do i bring my ride to have mine checked? is this something that an autoelectrical shop can help me with or any general autoservices would be able to do just the same?

mine takes about 10 mines before i see the needle moves up a hairline when idle and reading is different when cruising fast (about 1/4) and slow (about 3/4). i believe it used to stay at almost a half, regardless of the weather, and if on the move or stand still.

I discover lately that most cars specially the older once, has no thermostat. i wonder why almost 4 out of 5 mechanics still insist on removing it. (marami palang hindi marunong na mekaniko)

beware to second hand car owners. baka tinanggal ng previous owner yong thermostat nung car nyo or kung meron man, baka it needs replacement na specially if the rubber is torn. its a good time to check it out.

since there's no electrical connected / needed to open and close the thermostat, any radiator repair shop, your mechanic or DIY can check if a thermostat is installed or "removed/missing" in your cooling system. symply remove the elbow (the ones connecting the hose to the top of your radiator) and inside it sits the thermostat. hth
