I was always taught that lower engine temp can hurt you. Is this true?

 

some poeple say yes some say no i think the 160 is to low as i have seen ls1's dyno better numbers when warm then when cold.

 

i have it on mine and think that its great

 

the 160 is fine. the "itl run too cold" is an idiot wives tell told by mech's who dont have a clue.

 

lmao....well stated

 

Just remember....u need something to turn that fans on otherwise the 160 stat is pointless...i.e fan switch or programming

 

Yeah ... what Chesee48 said. You've got to do the fans along with the t-stat. Otherwise, it's not very effective.

I've been running a 160* t-stat on my car since the day I got it. No problems at all, coolant temps stay around 180 for the most part. Plenty of heat in the winter.

 

This wives tale is it revolved around the fact that metal expands when cool shrinks when warm.The temps are set to get the correct srinkage for clearances in various internal parts.And if temps are changed(cooler) metal parts are tighter dont get to the correct specified clearances.And wear them alittle more than original.You know the "dont rev your car when cold"not good for it way of thinking.???
Btw I run a 160 in one of my cars,but do think about this one.

 

I dont have a wife though?

 

lmao


ya i have the 160 stat with the manual fan switch and it works like a charm

 

I do 13 yrs. w/ the ball&chain,she aint told me nothin about that damn thermo

 

hehe.....

i have a gf thats sorta like a wife and she doesn even know what a thermo is....

 

Is this manual fan switch something you have to install in your interior, or is it something you connect to the fans themselves?

 

it goes into the interior....but there is a way to just program the computer for the fans to kick in earlier

 

Thermal Dynamics...I remember an article in a mag, think it was hot rod but not sure. They took an engine and wrapped it in all kinds of of insulation in the right places in order to have the combustion process at high temp, exhaust at high temp for velocity, and intake cold but pre heat the air just prior to entering the carb (old atricle...I am dating myself). This produced very high hp as opposed to keeping engine temp down. They did state that lubrication was a problem and an oil cooler was added to maintain longevity....anyone dyno be/af a 160 stat install from a stocker and see the diff ? I have put economisers on boilers to heat up the incoming feed water and heat exchangers in the incoming air flow to heat up the combustion air, but never have we tried to lower the temp of the actual boiler or combustion area to make efficiency gains...why would you do that to an engine block other than to lower lubrication temps that a cooler would accomplish...goes against simple thermal dynamics....bet this will spark debate !!!
