What should the engine temp be on a Chevy Duramax?
What should the engine temp be on a Chevy Duramax?
WRONG! I drove both trucks until reaching normal operating temperature and then used my laser temperature gauge on the motor itself to see it was exactly 195 degrees or less (reading from a variety of locations) and the gauge erroneously read 210 ( on my 2009). Both temp gauges I readjusted to read correctly.
What should the temp be on my GMC Truck?
After getting it back from having leaking intake gasket replaced, the temp would go up to 260 before it went back to 170 and then would sit for a little bit, go back to 210, back to 170, back to 245 or so, then back to 170, but It never seemed to run hot. I changed the thermostat with a brand new 190* from NAPA and it seemed to cure a little of it.
What should the engine temp be in a 2004.5 LLY?
Just got a 2004.5 LLY and have a question on the normal running temperature. Seems to be the average temperature is the half way mark between 210 and the far left mark. If I go up a large hill the engine will get up to 210 and stay there for a little while after leveling off the hill before settling back down to that middle notch.
What causes the temperature gauge to go down while you are driving?
The core, and thus the heating system, gets its thermal energy from the engine’s cooling system. Thermostat valves can fail in one of three ways: open, closed or stuck halfway. If the valve sticks in the closed position, coolant will constantly recycle through the engine without going to the radiator, causing the engine to overheat.

Why does my Duramax run cool all the time?
Running cool all the time, can put your MPG in the dumpster and affect performance. But also, the T-stats hold back the coolant flow, allowing the coolant in the radiator to release the stored heat. When they open, you get a rush of fresh cool fluid to absorb the block heat and start the process over again.
What’s the transmission temperature on a Silverado HD?
The information below shows shift range availability based on transmission oil temperature: All shift ranges available at −25°C (−13°F) or above. .2(Second) and 3(Third) shift ranges only at −35°C (−31°F) to −25°C (−13°F).
What does cold weather do to a Chevy Silverado?
When cold weather conditions are detected, the transmission raises part throttle upshift points after the 1(First) to 2(Second) upshift to increase engine speed. This feature shortens engine and cab warm up times. When the transmission is in this mode, upshifts may be delayed.
What’s the water temp on a Silverado Sierra?
Fans default on and ECT gauge defaults cold. Replaced water pump and coolant. They referenced a code P0128. Bill came to over $700. Seems to have fixed the issue. Previously I noticed temp settled around 190 degrees, and climb to a little over 200 degrees at a long red light on a hot January day. Now temp is a solid 210 degrees, no fluctuations.
Is the coolant level on my Silverado Sierra low?
A Low Coolant message may be displayed on the Driver Information Center of some 2017-2018 Silverado and Sierra models equipped with the 6.6L Duramax diesel engine (RPO L5P). An inspection of the radiator surge tank may appear to show a low coolant condition.
What kind of engine does a Chevy Silverado have?
Affected vehicles include: 2011–2016 2500HD Silverado 6.6L V8 Duramax diesel trucks with LML engines 2011–2016 3500HD Silverado 6.6L V8 Duramax diesel trucks with LML engines 2011–2016 2500HD Sierra 6.6L V8 Duramax diesel trucks with LML engines 2011–2016 3500HD Sierra 6.6L V8 Duramax diesel trucks with LML engines
How big is trans cooler on Silverado 1500?
My 2011 and 2012 were always up there as well, and in summer would routinely be over 200. The trans cooler on the 1500 is about 1/3 the size of the cooler on a 2500. And it is not positioned so that it sees clean air the way the 2500s cooler is.
What happens when a Duramax engine goes down?
Not only does this mean game-over for the engine, but it results in a truck that’s down for weeks (if not months) and a huge chunk of change missing from your wallet. The failure is most common in higher horsepower engines, but can still occur in moderately modified and even stock power plants.
What’s the normal engine temp for a 04.5 LLY?
My 04.5 LLY runs 195-200° now that I have the thermostats installed correctly. Summer, Winter,, it doesn’t care if the thermostats and cooling system are working properly. On a major climb with 10,000 pounds in tow it will climb to 210ish but have never seen it over 210-215°.

How long does it take for a Chevy Duramax to warm up?
Mine now takes about 5 miles at highway speeds to come up to full temp. It still won’t warm up a whole lot just idling, but it is much better with the new thermostats and will now put out heat. I got my thermostats at the local parts store in a kit that had both thermostats and the rubber gaskets. Merchant also has them.
Are there any high temp thermostats for Duramax?
Login or create an account to earn Points! The Mishimoto Chevrolet Duramax high-temperature thermostats activate at a higher temperature than the OEM thermostats, making them the perfect solution for Duramax owners who live in colder climates or have trouble reaching operating temperatures.
Which is the best Duramax 6.6L turbo diesel?
Perhaps the shortest lived of the 6.6’s, the LBZ Duramax is one of the most desirable amongst diesel enthusiasts today. The LBZ has the best performance and horsepower potential with bolt-on mods and was paired with a stronger Allison transmission than found in the LLY Duramax.

What happens to the coolant in a Duramax thermostat?
When the coolant temperature is below the rated thermostat opening temperature, the front thermostat valve remains closed to the water outlet and is opened to the bypass port. The bottom portion of the thermostat is raised off of the bypass port while at the same time the top portion closes the coolant flow to the water outlet.
What are the thermostats for a 6.6L diesel engine?
As the element is cooled, it contracts. This contraction allows a spring to push the valve closed. The 6.6L diesel engine requires two thermostats for correct coolant flow. The front thermostat is a dual purpose thermostat. The front thermostat controls the coolant flow to the bypass port and to the water outlet.
