Understanding what causes a truck to overheat and how to prevent it is essential. Hot Shot’s Secret offers the industry’s best high-quality additives and automotive products to help you keep your engine from overheating. These additives enhance your vehicle’s reliability and improve performance.
An overheated engine can cause serious complications such as engine breakdown or a seized motor, so it’s important to prevent overheating.
Why Is My Truck Overheating?
Determining why your truck is running hot is the first step to resolving an overheated engine. A few potential causes may be at fault.
Malfunctioning Water Pump
Your truck’s water pump circulates engine coolant through the cooling system. Engine coolant is an antifreeze and water mixture that removes heat from your engine, helping it stay cool during operation. The water pump prevents your truck from overheating, and it may be to blame if your truck starts running hot.
You can check the water pump’s functioning by removing the belt drive and spinning the pulley. If you notice resistance when you try to spin the water pump’s pulley, you will need to contact professionals for a replacement.
Blocked Radiator
A blocked radiator can hinder engine coolant’s circulation. Your truck’s radiator helps the cooling system dissipate heat, and a blocked radiator can prevent coolant from flowing through the system. If the radiator is blocked, it may require a power flushing.
Burnt Out or Damaged Fuse
A blown fuse in the systems connected to your truck’s cooling system can cause overheating. Examine the following fuses to check whether they are damaged or burnt out:
- Heater
- Blower motor
- Air conditioner
Replace any blown or damaged fuses before driving your truck again.
Faulty Thermostat
The thermostat regulates coolant flow to your truck’s engine, making it a vital part of the cooling system. If the thermostat is stuck in the closed position, it restricts coolant from flowing to the engine and eventually causes it to overheat. A professional technician can test your thermostat and recommend if you need a replacement.
Cooling System Leak
When coolant leaks from your system, it can’t cool the engine. If your truck overheats, you may have a cooling system leak due to one of the following complications:
- Faulty hose
- Worn out gasket
- Damaged engine block
- Radiator damage
Insufficient Engine Oil
Low oil levels can also cause truck overheating. Oil lubricates your engine components to prevent heat-inducing friction and low levels can cause poorly lubricated components to produce more friction and heat. Engine oil also works like coolant to transfer heat away from your truck’s engine. Low oil levels can reduce or halt this heat transfer.
What Should I Do If My Truck Is Running Hot?
Truck overheating can cause significant vehicle damage, such as a seized motor or engine breakdown. If your truck overheats, take the following actions to remain safe and prevent further damage:
- Turn off your air conditioner: Turning your truck’s air conditioner off and your heater on to its maximum setting helps draw heat away from your engine. Using the excess heat can help cool your engine down until it’s safe for you to pull the truck over.
- Stop driving: Pull over and avoid driving until you resolve the complication.
- Let the engine cool: Give your engine time to cool down before opening the hood to protect yourself from burns and smoke.
- Find the cause: Check the components and systems discussed above if you have the skills and knowledge to do so. If you don’t have truck maintenance experience, contact a professional to inspect your systems and diagnose the cause.
- Schedule repairs and replacements: Repair or replace faulty parts or schedule professional repair before driving your truck.
How to Prevent a Truck From Overheating
Proper maintenance helps prevent engine overheating and can increase your truck’s longevity. Consider the following tips to avoid overheating:
- Check oil and coolant levels: Check oil and coolant levels frequently, and add more when necessary.
- Change oil consistently: Changing your oil every few months helps keep your systems clean to prevent friction.
- Schedule regular inspections and coolant exchanges: Inspections help you catch potential complications before they cause damage, and coolant exchanges help your cooling system operate as efficiently as possible.
Hot Shot’s Secret Additives for Oil and Engine Maintenance
High-quality oil additives improve base motor oil to protect your truck engine’s metal components. With the right products, you can enhance your engine’s performance, prevent overheating, improve your fuel economy and extend the time between maintenance intervals. Hot Shot’s Secret offers some of the market’s top engine oil additives and a full line of high-quality coolants to help you protect your engine.
FR3 Friction Reducer
FR3 Friction Reducer is a 100% synthetic friction-reducing oil treatment that works with conventional or synthetic oil. We combine three proprietary lubricants to create this additive, which provides several advantages for your truck:
- Decreased engine friction to prevent heat generation
- Improved oxidation stability
- Greater oil film strength
- Up to 43% reduced engine wear
- 4.7% greater fuel economy
- 5% greater horsepower at maximum levels
The Original Stiction Eliminator
The Original Stiction Eliminator improves gasoline and diesel engine performance, cleaning and lubricating the engine’s turbo, rings, oil pump and hydraulic electric unit injectors (HEUI injectors). This industry-leading additive removes the sludge and varnish known as stiction that burnt oil produces, and it offers the following benefits:
- Overheating prevention
- Up to 62% reduced engine wear compared to base oil
- Restored power and compression
- Improved fuel economy
TBN Booster
TBN Booster enhances your base oil by increasing the Total Base Number (TBN). It replenishes oil detergents as they gradually decrease, protecting your truck’s engine from acidic, corrosive conditions that could cause overheating. You can depend on TBN Booster to strengthen and stabilize your host oil, extending the intervals between oil changes.
