Please to use a thermometer in the radiator after the engine has run about 10 minutes to test the actual temperature of the coolant.
You may also choose to put a piece of flat cardboard over half of the front of the radiator to see if that makes it heat up more.
The temperature should be about 180 degrees, unless you have added a 160 degree thermostat to the engine, in the which case the radiator temperature should be nearly 160 degrees.
If the radiator shows the proper temperature, perhaps the temperature gauge on the dashboard or the engine block sending unit is defective.
God bless your efforts.

SOURCE: ford ranger truck overheating

I have had this happen with my ranger. Changed everything I could to try to fix the over heating. It turned out that I had a small leak in my head gasket and it was allowing exsaust gas to go into the cooling system witch was over pressurizing it. Also the air from the exsaust will heat up much faster than liquid making your thermostat to read hot and will not be able to blow hot air in the cab because there is no liquid going to the heater core. This happened to me when my blet came off and I tryed to make it home. If you had it over heat for a long peirod of time it may have ripped the head gasket.

You may have a stopped-up heater core. It's a little radiator inside your dash; it's where the heat comes from. I don't understand why the temp gauge isn't reading any higher than that...

Headgasket must be checked. and check that you have enough radiator fluid. Also check for warped/cracked cylinder head.

How to override cooling electric fan on 2002 volvo xc70 2.5T to assist cooling when towing trailer
the fan will come on when the coolant temp reaches a preset temperature normally around 85 C
by passing the cooling temp sensor to have the fan running all of the time is a pointless exercise as if the thermostat is not open there is no coolant to cool and if the thermostat is fully open then the fans will be running anyway
what you should be thinking about is finding out why the vehicle is overheating when under load
have the fault codes read first
possible reasons are
at converter blocked
HO2S faulty
EGR problem
radiator cores blocked
transmission over heating and putting he radiator under stress coolant temp sensor faulty or relay faulty or fuses blown

Cummins isx in a 2014 kenworth changed fan clutch and thermostat but still wont build temperature above 170
170 F is 76.6 C which is around 10 C lower than is required for diesel engine operation
Cummins have thermostats at various opening temperatures and it is in this area that you should be concentrating your search
How it works
coolant in an engine is recirculated until engine operating temp is reach ( around the 85C mark) at which point it starts to open
That allows water to pass to the radiator and the air cools the coolant by air passing through the fins The coolant flow is low and so the temp keeps rising until the thermostat is fully opened and full flow is through the radiator
Now if there is insufficient air flow to lower the coolant temp as in slow moving / heavy load and pulls , then the fan clutch cuts in to assist with the air flow
so back to you statement , what you need is a thermostat with and opening temp or 85 C(185 F and fully opened at 95C (203F)

What could cause my 2000 Nissan exterra to overheat while idling? I have replaced the clutch fan, censor and thermostat
Don't know where you're located, Tamela, but warmer climates & idling, don't go very well together. if you're idling for long time, maybe shut the engine off. Or maybe a little more rev on the idle speed. good luck!

I have a 94 toyota v6 pickup, just replaced the radiator. topped off coolant, ran for approx 10 mins. temp gauge move to nomal operating temp. then turned on a/c to put a load on it, the temp then went up....
Did you recheck the water level at the radiator filler cap after the engine was at normal temperature (ie after about 15 mins idling with heater control on full and fan on Low) because it sounds like there is an air lock in the system. Air lock should clear after thermostat starts to open. This is indicated by the top radiator hose becoming hot to touch.

250 TOO HOT FOR ENGINE AND TRANSMISSION. SOUND LIKE COOLING FAN CLUTCH BAD ITS FREEWHEELING NOT LOCKING UP TO DIRECT DRIVE TOO COOL ENGINE OFF BECAUSE THE FAN CLUTCH THERMOSTAT NOT WORKING THE HOT SILICONE OIL CAUSE IT TO EXPAND TO PUT RESISTANCE ON CLUTCH TO PUT DRAG ON FAN CLUTCH CAUSING IT TO LOCK IN GIVE IT DIRECT DRIVE.I WOULD STILL REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP IF TEMPERATURE STILL 250 DEGREES YOUR RADIATOR AND COOLANT SYSTEM NEED FLUSHING.

No heat ..help installed new heater switch, replaced water pump..replaced coolants, and thermostat......................what else could it be? Nissan 2003 GXE Sentra 1.8 L Engine/...
you could have an air pocket in the cooling system that has to be burped. With a cold engine, park uphill and leave the radiator cap loose. Fill radiator and coolant reservoir. Start engine with cap loose and run at 1500 rpm until temp gauge reads normal. Feel if top radiator return hose from engine to radiator is hot. If yes, coolant is flowing and thermostat is open. If cold, thermostat is not staying closed until engine is hot.

report results.

Got a 96 crown vic that runs but smoking white smoke from under the hood and it runs hot ....the resevoir is full so there is no leak there and i replaced the thermostat but it didnt work
you ether have a coolant leak or one of these are the problem thermastat,fan clutch,water pump,radiator, try this start car when it reachs normal temp open hood and pinch the top radiator hose if it is hot water is flowing thermastat is good now open radiator with a towel slowly while it is runing see if the water is moving if it is you water pump and radiator are good, now at some point in this time you should have heard the fan get loud if not your fan clutch is not work it mounts to the front of your water pump and is normal to go out because they lose about 250rpm a year which does not give them much of a life, dont forget to check your heater hoses they could be leaking
