What should the temperature be on a Duramax LB7?
What should the temperature be on a Duramax LB7?
I’ve got a new to me LB7 and I think that the temperature is a little low. On all of my other vehicles (mostly GM), operating temp is 210, however I cant get the Duramax above 170 (according to the gauge it is 180). I took the reading via my OBDII reader, it is 170-172F.
What should the temperature be in a GMC Duramax 04?
My 04 runs this cool also. In town it is 160-170 all the time. If I drive it a little bit harder than normal it will warm up or if I get on the highway at 65-70 it will warm up. Not sure what the low side thermostat is but I would bet its a 165-170 since this is where they like to run.
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.
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.
What should the transmission temp be in a Duramax?
If you own a 2001-2004.5 LB7 Duramax your normal operating temperatures will run around 160-180 degrees. These transmissions will warm up when towing or driving in the summer months. 200-225 is very common when the ambient air temp is 80-100 degrees and your transmission is under an increased load.

What should the running temp of a service truck be?
I have a 2003 2500HD Service truck on a 3500 chassis. 7800 lbs with tools. and it always read lower than 190 or under. New radiator, water pump and it reads 210 consistent running temp now. Something about it having a leak or pressure loss that causes it to read lower than it is?
