Why does my coolant go from 180 to 210?
Problem continues except now it goes from 180 swings up to 210, then back below 180, then to 180 and repeates this all the time regardless of how long I drive. Anyone have any other ideas? New engine, new radiator, new theromstat, new temp sender…what could it be? Have you bled the air out of the system? That sounds like it might be the problem.
What should the coolant temp be on my Chevy?
I though the thermostat might be broken, so I replaced it with a 180 (was a 195). Problem continues except now it goes from 180 swings up to 210, then back below 180, then to 180 and repeates this all the time regardless of how long I drive. Anyone have any other ideas?
What causes high fluid temperature in hydraulic system?
The temperature at which this occurs is dependent on the viscosity grade of the fluid in the system and can be well below 180°F. High fluid temperature can be caused by anything that either reduces the system’s capacity to dissipate heat or increases its heat load. Hydraulic systems dissipate heat through the reservoir.

What is the cooling capacity of a hydraulic system?
PLtotal = PLpump + PLvalves + PLplumbing + PLactuators. If the total input power lost to heat is greater than the heat dissipated, the hydraulic system will eventually overheat. Installed cooling capacity typically ranges between 25 and 40 percent of input power, depending on the type of hydraulic system.

What should I do if my coolant temp keeps fluctuating?
It’s pretty common for the temp to fluctuate this much, certain locations for the temp sender are more sensitive than others. If you are worried about air trapped in the block, drill a couple 1/8 inch holes in the perimeter of the thermostat flange. This will drain any air pockets in the block within a week or so.
What’s the best way to get coolant to flow?
Another trick to bleeding air out is to drill a 1/8″ or 1/16th” hole in the thermostat, if it doesn’t already have one. That helps air escape when it’s closed, but generally won’t flow enough coolant to affect the operation/heating of the engine. Those who can, do. Those who can’t, criticize it on the internet.
