Cat 3208 oil cooler- engine oil temp hi- 89SP
My engine oil temp is running HI(manual says 230-270). Where is the oil cooler
and how does it work? Can you work on it your self? Can it be removed and fixed or repaired? Anybody ever done this? What else could cause the hi temp. Dip stick shows full, no laeks... Thanks for any ideas or help Ed Gardels 89SP Arlington Texas |

Defective gauge and/or sender, wiring. Can't help with the oil cooler.

Hi Ed, As you know, diesel engines can and will suffer serious damage even as the result of relatively minor overheat conditions. Is the water temp also high? Could be several things or a combination of things. Oil should be changed at least every 100 hours because carbon build up in the oil reduces its ability to cool. Radiator could be compromised in some way either internal or external. Have you checked the coolant level not using the sight glass? The impeller on the water pump could be worn. You know, considering how expensive an overheated diesel can be, I would take it to good shop and let the pro's diagnosis it. Just my two cents worth.

One other thing while we are on this subject, I read that the water temp gauge doesn'talarm with no water but an exhaust temp alarm will work. Does anyone have any experience with an exhaust temp alarm?

I'm not sure that is hi? what should the temp be? my 8v92 gets to 250 and my
cummins n-14 get to 195. The cummins pulls a truck that is unloaded most of the time ant the 8v92 a bus that is at max load every time it pulls out. too often folks try to reduce tepms via after market mods and not deal with the factors that cause the extra heat. That is the problem with all the shade tree t stat mods and extra fan measures. the operator will lose the signal that a high temp warns of a failure which causes heat.

The oil cooler is a water to oil unit located just above (attached)to the oil filters. It is replaced as a unit and is no fun to do as the bolts holding it onto the block are hard to get at. Additionally the unit is around $400 exchange. I would say if your water temp is not elevated then the gauge is the first place to look/hope. Bob Criss 90SP Bethel Park, PA > |

Oil cooler on a 3208 is mounted on the engine block bottom right side. Don't
think there's much to go wrong in the cooler itself. I think it functions by using the engine coolant. I too would replace the sender or gauge or at least use an infrared thermometer to get a sense of whether the oil temperature system is functioning correctly. If the oil is truly running at those temperatures, I would definitely be using synthetic oil until the problem is solved since it can usually maintain it's properties at higher temperatures. Do you have an EGT gauge? If so, what are those temperatures. I think higher EGT's can increase oil temperatures substantially since the oil is running thru the turbo. Has the oil always run at this temperature or is it a recent development? Does it run at this temperature all the time or just under heavy loads like on a steep grade? If it only gets this high under load, check to make sure that your cooling fan is functioning correctly. What is your transmission fluid temperature? If the engine coolant temperature is also high, I'd suspect a malfunctioning thermostat.
