Oil & Fuel "Normal" temperature on gauge L3400D

[outoftractorluck]

Temperature indicator used to sit around the middle of the gauge. Last year I tightened the fan, flushed out the coolant and replaced it, just regular maintenance. I've noticed that now the temperature gauge indicates maybe 1/8th at hottest, summer or winter. Don't know if it was the flushing or what. Everything seems OK but is low indication normal? Do I need to change the thermostat? Anyone else seen this?

My L3200 sits at 1/4 on the thermostat most of the time. Pushing it to the limit with the tiller on the PTO will heat it to 50%. I believe our tractors are almost the same a generation apart with only trivial changes.

My L3400 DT BOTA runs cool even on the hottest of SW Fla days. Might jump up to 1/4 temp gauge reading.
IMO your temp guage is working fine. I always kidd folks that if I moved to a real cold climate I'd have to block up the front air restriction flow to get guage to rise some.

Up here in the frozen north that is exactly what I do. On a cold day you will not get the engine up to temp unless you do.

Something has changed.
A thermostat check or change would be in order.
Nothing you did would likely be the cause of your low guage reading.
A thermostat change is neither difficult or expensive,and your engine wants to be run at full temperature for best engine life and fuel efficiency.

A quick check on cars and equipment is to run a cold engine 3-4 minutes under load,grab the upper coolant hose and feel the temperature.
The hose should still be cool-if warm,the coolant is passing the thermostat as the engine has not yet warmed up enough to open the thermostat.
Hope this helps-Good Luck!

my L2800 never goes past 1/4 reading no matter how hot or how hard i use it.

I don't think you have a problem... my L3400D with 100 hours on it is exactly the same way, and runs perfect.

Thanks for all the feedback. Makes me feel secure.

i. Did. The same. With. Mine. Now. It. Runs. Right on. The red. All the time. What. Happened.

Mine runs just above the small tick mark on the temperature gauge, maybe 1/4? Only time it goes above that is if the radiator screen gets clogged with chaff.

For what it's worth my 2000 L3010 with 1100hrs runs the same. If I work it hard for several hours it get between 3/8 and 1/2.
