At 65 and over, the engine shouldn't need a fan at all. The air flow through the radiator should be more than enough (as in auto racing). Therefore, I would suggest that the radiator coils (exterior) may be blocked with road dirt, etc.. I don't know what you used to flush the system, but on an older vehicle, rust and scale can build up and hinder the heat transfer ability of the coolant. You may have to flush with something that will dissolve rust and scale (you may have already done this). I would also suggest evaluating your choice of engine oil weight for your type of driving. You might also consider installing an oil cooler as the engine oil is a main component of cooling. Good luck!

You may want to try replacing your Fan Clutch ( the silver part in the center of the fan blade.

That is typical that the heater won't work well when the engine is overheating. Often because of low coolant, also the htr. core is the highest part of the coolant system. Bite the bullet and check for a head gasket problem-a compression test should tell you.

First you need to purge the trapped air out of the system. Go to a shop that has evac/fill equipment and tehy can do it for about $75. It is ahrd to get air out. park uphill and rasie front of truck as high as possible, and keep cap loose during warm up. It will burp air. Then tighrten cap & let it cool while keeping the reservoir full during cool down. Repeat at least once. Make sure hose from rad to reservoir is tight at both ends to avoid sucking air in.

report results.

please rate if helpful

No heat is a sign of trapped air.

If the heater core is leaking, you would get a lot of steam that would smell "sweet". That would also leave you low on coolant, which could be a source of your overheating. If it's more of an electrical smell, you may have a blower motor or a blower motor resistor going bad, but won't cause the engine to overheat.

Heater blows cold air. I have replaced thermostat,


Not an expert by any means, but i know my ranger.. I had a small leak at the top of my radiator that still cooled the engine but didnt have enough pressure to get to the heater. The heater hoses travel up over the engine and just were not gettin anything to my heater core. That or make sure the heater control valve is operating.

Overheating 02 ford ranger


the cooling system has to be bled. Did you bleed the cooling system ? first you fill the radiator with coolant and water. Then turn on the engine and and run to operating temperature. Most cars have a bleeding screw located at the thermostat housing. Turn of the engine and with a fairl long screwdriver turn the screw counter clockwise and remove the air until coolant is the only thing coming out. Refill and repeat procedure.Refill with coolant until full. Be careful not to burn yourself with the steam coming out with the air.

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.

2.3l ranger keeps overheating, been through two radiators already.


Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.

1990 ford ranger is overheating


If the cooling system has no bleeder valves to vent air, you may have to temporarily loosen a heater hose to get all the air out of the system...Also check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem....Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.

Overheating


If the vehicle is overheating then you need to keep your eye on the heater core. the heater core was an issue with this model and when it finally goes out so will your engine!
