Why is there an engine overheat alarm after it runs for 5 - 10 minutes?


If the engine really is full of hydraulic oil rather than engine oil, that could explain the overheating problem.

What would cause my hydraulics to keep heating up on a 648g3 skidder?


Friction is usually the cause of hydraulic overheating. Every time the hydraulic oil moves through the system the moving of the hydraulic fluid against the hoses,pumps, cylinders , etc. creates friction. Any restrictions such as valves or filters can be hot spots because of the friction created as the passages get smaller the fluid moves faster creating more friction. Friction = Heat.
I would check the filters to make sure they are clean. Check the valves to make sure they are opening fully. Check hoses for any kinks or pinched spots.Try to operate the skidder at the lowest r.p.m. need for the work being done. Over revving can also cause heat buildup.
Hope this helps.

Y dose the john dear 6330 run hot all the time even after it blowen out



Engine or hydraulic system overheating clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif Coolant system low on coolant in 6020, 6030, 6030 Premium, 7020, 7030 and
7030 Premium Series Tractors.

]clearpix.gif//-->
Symptoms
After several hours of work, warning system indicates hot engine coolant or hot hydraulic oil.
Situation or Problem
Coolant level in reservoir is between the "MIN" and "MAX" range but engine or hydraulic system is overheating.
Summary
Air is entering cooling system, hindering coolant flow. Check coolant level. Fill to the "MAX" line on the coolant reservoir.
Bleeding Cooling System:
The bleed valve (see Operator's Manual for location) on the radiator must be closed when the tractor is operating. Open the valve when coolant is drained or filled. If the bleed valve is left open, coolant will internally bypass between the low temperature circuit and engine high temperature circuit causing overheating. When bleeding the system, open the bleed valve and run the engine with no load for 5 minutes at 1700 rpm. Then shut engine off for 5 to 10 minutes before closing the drain valve. Check the coolant level. If level is below the "MAX" fill line, repeat this procedure until coolant level stays at the "MAX" line.

1993 Toyota Camry V6: Engine Overheating Prob


Yes if it hydraulically operated it could be because the pump for the fan is bad. If I am not mistaken the fan is run off of the power steering pump correct. check and make sure the pump is working correctly. I have not seen a hydraulic motor on a car I know they put them on a lot of diesel trucks like humvees and some Chevy diesels but not on a car. Most are usually electrical. I know on humvees with a hydraulic fan they have a fan controller check this and make sure it is working right you can unplug the controller and the fan should stay ingaged and turn faster.

Overheating and now engine 'clicking noises.


possible causes of overheating are, dirty cooling system, clogged radiator, bad thermostat. Use only distilled water with a good quality coolant.

still overheating? have your top head checked - warped head, valves, valve seats, etc. You might need to have your engine's compression checked if it is still within specs.
