engine temp drops under load?

[dockinrez]

Noticed while driving today that my engine temps drop under acceleration from a dead stop or giving it more foot on the highway. Could this be bad?? Anything I should look out for or start looking into? The sooner I can address the little issues the soon I can out my turbo setup on.

When you accelerate, more air is passing through the radiator, cooling it faster.
Also, your water pump is mechanically driven, so it pumps faster as the engine turns faster.

is it overheating any?

Check your coolant level. Mine was doing the same until I topped it off.

[deevergote]

The cooling system is a closed system... so if the coolant level is low, that means you are burning or leaking. Either one is indicative of a problem that will only get worse in time. Best to fix it before it causes damage, if that's the case.

if it drops isn't that a good thing??? i mean the cooler the engine runs the better

[deevergote]

To a point, the cooler the better.
But if it's abnormal, it could be indicating a more serious problem.

Like, if you're getting amazing gas mileage, that's good, right? Unless it means you're running dangerously lean, which will fry your internals pretty quick.

I had this issue after replacing heater hoses, thermostat.
with about 10k on the new water pump.

turns out it was abad headgasket.
was real weird because it would cool under load.
but still with everything replaced had issues.

this was my scenario tho.

No over heating. new timing belt and water pump maybe 2k ago. Haven't done a compression test or anything. It doesn't seem to effect anything. I'm stuck at work till 7am so I'll check coolant levels then.

No, the engine is designed to run at a certain temperature. Unless you've done some serious mods and know what you're doing you want to keep it at the proper temperature.
