Service | Farmington, MO Summer heat and trailer season are coming. A cooling system check in March costs a lot less than a tow off the shoulder of US 67 in July. Most people don't think about their cooling system until the temperature gauge climbs or steam rolls out from under the hood. By then it's usually a bigger repair than it had to be. Your Ford's engine makes a lot of heat, and the cooling system's job is to carry it away. Coolant runs through the engine, out through hoses to the radiator, and back again, pushed along by the water pump and controlled by the thermostat. When one piece wears out, the rest of the system can't keep up. Spring is the right time to check it, before the hot, humid weeks and the boat trips to Lake Wappapello and Clearwater Lake. Quick answer: Watch for a rising temperature gauge, a low coolant message, a sweet smell or colored puddles under the front of the vehicle. Ford specifies the coolant type and replacement interval for your engine in the Owner's Manual, and on many Fords the first change comes around 100,000 miles or a set number of years. A spring inspection of hoses, the water pump and radiator is cheap insurance before summer towing.

The temperature gauge is your first warning. On most Fords it sits near the middle once the engine warms up and barely moves after that. If it starts climbing toward hot, or a coolant temperature warning comes up on the cluster, the system is losing the fight. Other signs show up before the gauge moves. A sweet, syrupy smell after a drive often means coolant is leaking onto something hot. Orange, yellow or green drips under the front of the truck are coolant too. A heater that blows cool air on a cold morning can point to low coolant. Coolant doesn't get used up like fuel. If the level keeps dropping, it's going somewhere. Pull over for these Gauge climbing or a temperature warning. Pull over somewhere safe and shut the engine off. Driving an overheated engine can warp a cylinder head or blow a head gasket. Steam from under the hood. Stay back and let it cool. Never open the coolant reservoir cap on a hot engine, because the system is under pressure and can spray scalding coolant.

Coolant doesn't get used up like fuel. If the level keeps dropping, it's going somewhere, and that needs a diagnosis. What Coolant Does Your Ford Use, and How Often Should It Be Changed? Ford fills its vehicles at the factory with Motorcraft coolant made to a specific Ford specification, and many recent models use Motorcraft Orange. Ford has also approved Motorcraft Yellow for servicing many vehicles that came with orange coolant, so don't be surprised if the color in your reservoir changes after a visit. The service order will note what we used. What you shouldn't do is grab whatever jug is on sale at the parts store. Mixing coolant types can cut the protection against corrosion that the system depends on. Your Owner's Manual lists the exact coolant for your engine. Change intervals vary by model and engine. On many Fords, the schedule calls for the first coolant replacement at around 100,000 miles or a set number of years, then on a shorter cycle after that. Ford's own example for a 2019 Ford Escape is the first change at six years or 100,000 miles, then every three years or 50,000 miles. Check the scheduled maintenance section of your Owner's Manual, or ask us to look it up by VIN. Coolant doesn't get used up like fuel. If the level keeps dropping, it's going somewhere. Which Cooling System Parts Wear Out? Coolant is only half of it. The parts that carry it wear with heat and age, and a cooling system inspection looks at each one. Hoses: rubber hoses soften, swell or crack over time. A hose that feels mushy or shows cracks at the clamps gets replaced before it splits on a hot day. Water pump: it keeps coolant moving. Signs of wear include a weep or drip near the front of the engine, a whine or grinding noise, or slow overheating. On some Ford V6 engines the pump sits inside the engine, driven by the timing chain, so a failing pump can leak into the oil instead of onto the ground. Radiator: fins clogged with bugs, chaff and road dirt can't shed heat. Corrosion and seam leaks show up as crusty residue or drips. Thermostat: a stuck thermostat can make an engine run hot or never warm up. Reservoir cap: the cap holds pressure in the system. A worn seal lets coolant boil off sooner. Farmington driver tip If you drive gravel roads or work around hay fields, check the front of the radiator a couple of times a summer. Dust and chaff pack into the fins and cut airflow right when you need it most. Schedule Service See Service Specials Why Does Summer Towing Put Extra Strain on the Cooling System? Pulling a trailer makes the engine work harder, and harder work means more heat. Add a 95 degree July afternoon and humidity, and the cooling system has very little room for a weak hose or a clogged radiator. Ford's maintenance schedule counts towing as a tougher operating condition for that reason. The hills are where it shows. Pulling a camper up the grades on MO 21 through the Arcadia Valley or a bass boat south toward Wappapello on a hot afternoon will push the temperature gauge on a truck with a weak system. A healthy system keeps the needle steady. If you plan to tow this summer, book the cooling system check now. It pairs well with the transmission and brake checks a towing truck needs anyway.

Overheating What should I do if my Ford starts to overheat? + Pull over somewhere safe, shut the engine off and let it cool. Don't open the coolant cap while it's hot, and call us or roadside assistance before driving farther. Can I keep driving with the temperature gauge high? + Driving an overheating engine can warp the cylinder head or damage the head gasket, which turns a hose repair into a major one. Why does my heater blow cold air in winter? + Low coolant, a stuck thermostat or air in the system can all cause it. Have it checked, since the same problem can lead to overheating. Coolant What color coolant does my Ford use? + Many recent Fords are factory filled with Motorcraft Orange, and Ford approves Motorcraft Yellow for servicing many of those vehicles. Your Owner's Manual lists the exact specification. Can I mix different coolants? + Mixing types can weaken corrosion protection, so stick with the Motorcraft coolant Ford specifies for your engine. How often does Ford coolant need to be replaced? + It depends on the model and engine. Many Fords call for the first change around 100,000 miles or a set number of years, then on a shorter cycle. Parts and Repairs How do I know if my water pump is failing? + Watch for a drip near the front of the engine, a whining or grinding noise, or a slow climb in temperature. On some V6 engines, coolant in the oil can be a sign. How long do radiator hoses last? + Hoses wear with heat and age rather than a set mileage. A technician squeezes them during inspection and replaces any that feel soft, swollen or cracked. Is a coolant leak always visible? + Some leaks only appear when the system is hot and under pressure, and internal leaks never reach the ground. A pressure test finds them. Towing and Summer Should I check my cooling system before towing season? + Spring is a good time, because towing in summer heat gives a weak system nowhere to hide. Ford treats towing as a tougher operating condition in its maintenance schedules. Does the AC affect engine temperature? + The AC adds load and its condenser sits in front of the radiator, so a clogged front end can affect both. Our June 2025 AC article covers the cabin side in more detail. What can I do on a long grade with a trailer? + Keep an eye on the temperature gauge and give the truck a lower gear on long climbs. If the needle rises past normal, pull over safely and let it cool.
