Why does my temperature gauge keep going up?
Low coolant, a clogged radiator, bad water pump, and a handful of other things could all be a potential issue. Replacing a thermostat is much easier than replacing an engine, so keep an eye on your temperature gauge.
What temp should a 5.9 Cummins run at?
Registered. If it is around 195+ you are OK a diesel needs to run around 200 to get the most from your fuel.
What is a dangerous EGT temp?
The absolute maximum safe EGT range is debatable. Our universal rule of thumb, regardless of engine make/model/year, is to not exceed 1250° F and not to operate in the 1200° F – 1250° F range for an extended period of time.
What temperature should a Dodge Cummins be?
At idle the truck should run 188-192. With no load but highway speeds in plus 100+ outside temps you are going to get an increase into the low 200’s and there’s really nothing to worry about.
How long can you drive with thermostat stuck open?
Open is fine as others have stated, the only thing is that since your car will not reach the ideal operating temp, (yes, you can overcool a car) your gas milage will take a hit becuase the ECU thinks the engine is still trying to warm up. my friend drove his car for 4.5 YEARS with stuck-open thermostat…
What is the max EGT for Cummins?
It is Cummins opinion that the max EGT’s, whatever they may be, of the stock motors are safe for extended intervals. There are a more things to conside than just the EGT’s. Initial injection timing, dynamic inection timing, injection event timing, valve overlap, etc, all play to what we see as a final EGT.
What should EGT be at idle?
The longer it idles the cooler it will get, but no cooler than around 250* if the engine is at full operating temperature unless its VERY cold outside. When the weather is warmer summer then typically EGT’s will stay more around 300-325* depending on how long its been idling.
What should the temp of the Dodge 5.9 run?
Posted By: steelpony5555 on 12/09/10 02:18pm According to my Dodge mechanic he says the 5.9 does take awhile to warm up. And it runs just under 200 on flat road empty, 200 towing the 5er on flat road, but does jump to around 210 going up a hill in 100 deg weather with the 5er on.
What should the temp of a diesel engine be?
A diesel might idle at 200:1 (air to fuel) which won’t make much heat. Under a heavy load (like towing a heavy trailer), it might get to 12:1. Until recently (with the new DPF equipped diesels) there was no throttle plate to restrict air coming into the diesel engine. My 2007 Cummins runs wide open (for air) at all times.
Is it normal for a Cummins diesel to be slow to heat up?
Well, you’ve received mostly responses from people who live in warmer climates. Slow to heat up is normal for a diesel, especially a Cummins. Remeber, there’s 1100# of cast iron under that hood to warm up.
What should the temp should the 5.9 run?
Mine runs just under 200, might see 210 pulling a hill under tow. In cold weather, it’ll take 5 miles at highway speed to bring up any heat.
