running too cool??

hey guys, so i just got done putting my edge cts in and took it for a testdrive.. i found my ect vs eot difference good with the most diff being 11 deg..( it better be since i just repalced it) but i found my ect and eot stay around 155-160 and trans about 150 also. now i much rather have it this way than too hott lol. but doesnt it seem a little too cool to you guys?? oh and ambient temp was 70 outside

Re: running too cool??

How long did you drive it?

Once warmed up, ECT should be low to mid 190's and EOT around 200+ running down the road unloaded.

Re: running too cool??

Yea that is a little cold.

When I was in Tahoe for a while during the winter my temps would never get above 160. So I used a piece of card board to block some of the air flow. That brought my temps up to 190ish and trans temps got up to 140. It also held the heat in the eng longer.
With any engine running cold, there will be water build up in the engine due to the temps not getting high enough to evaporate the water that is taken in from the air.

Re: running too cool??

your thermostat is stuck open, replace the thermostat you should be seeing 190ish ECT and EOT temps when warmed up

Re: running too cool??

too cool isn't good for these trucks

Re: running too cool??

from deselsite Ignore the 203 t stat referance because it's for a 7.3
but you get the idea
Quote:
Answer: You want the engine oil/water temps to be warmer so you get a cleaner, more complete combustion. This can actually bring exhaust gas temperatures DOWN. Diesel ignites from heat of compression. The idea is to compress the air charge to build enough heat to light the fuel, but if it's fighting against a low engine heat, the fuel will ignite, but not as complete as if the cylinders were just a bit warmer. The more complete the combustion, the cooler the exhaust temperatures. Diesel fuel combustion tends to complete best at temps above 200*. An added benefit from using the 203o thermostat is better working cab heaters in the cold months. Another added benefit is better fuel economy. We have seen everywhere from 1-4mpg increases. This depends on climates, driving habits, etc. Even a modest .25 mpg increase will pay for the thermostat in a few
