The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.
When the head gasket begins to fail, the engine may have no symptoms at all. They only begin to occur when the leak has reached an engine oil passage, engine coolant passage or the engine cylinder.
When that happens, the engine may be very difficult to start, and run roughly when idling. There may be oil or coolant leaking, and the engine may begin to overheat, or at least run hot. At this point, there may be coolant in the engine oil pan — this will look creamy and lighter in color than the oil. Also, the radiator or engine coolant reservoir may have a gurgling sound, the presence engine oil, or smell of combustion. And the check engine light will come on.
The coolant being burned in the engine will produce white exhaust that smells sweet, like engine coolant. When the head gasket fails completely, the engine will overheat within minutes of starting, will stall and then won't restart.
A failing heater core may cause the car's interior to smell like engine coolant. The smell will become worse when the heater is turned on. The engine may also begin to run hotter until the vehicle is repaired.
The worst-case scenario is the engine overheating, which can cause extensive engine damage.
If the heater core is clogged, the air that blows when the heater is turned on will not be very hot.
Problems with the intake manifold gasket can create the following symptoms:

A failing radiator can cause the engine to run hot or overheat. Most radiators are made of metal and plastic. The plastic parts can become brittle and crack over time, causing a leak of coolant (typically green or pink in color). All manufacturers have a recommended service interval for coolant renewal. As the coolant ages, the additives breakdown and being to form solid deposits. These deposits will build up in the passages of the cooling system and will eventually clog components, including the radiator. A leaking or clogged radiator must be replaced. Some automatic transmission cars will also have a transmission cooler integrated into the radiator. Lines going to and from the transmission circulate transmission fluid to help cool the transmission in heavy duty applications such as towing or off-roading. If this integrated cooler fails, it can allow transmission fluid and coolant to mix. This will causing shifting issues in addition to overheating.
A coolant leak may be noted from the hoses. Coolant hoses can be damaged by oil leaks, or age. This will lead to swelling or cracking, it is suggested to replace the hoses before they begin leaking to avoid potential overheating.
The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.
A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.
A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

If a vehicle is overheating, a bad thermostat could be the problem, and a damaged thermostat housing is more likely to produce a coolant leak, either from a cracked or warped housing or a failed seal to the engine. The thermostat housing can be made of metal or plastic. And the housing can be a stand-alone part that is separate from the thermostat, or (on later model vehicles) can be integrated with the thermostat and replaced as a single unit.
The two most common signs of a bad pump are leaks and noises.
Leaking water pumps can result in damage to the drive and timing belts, and cause the engine to overheat. A failed water pump can be caused by other problems in the cooling system, such as a bad thermostat, radiator or head gasket.
When diagnosing a coolant leak in your 2013 Ram 3500, it's essential to adopt a systematic approach that begins with the most accessible components. Start by inspecting the hoses connected to the cooling system, as they are often the culprits behind leaks due to wear and tear. Next, examine the radiator for any signs of damage or corrosion, as a compromised radiator can lead to significant coolant loss. Don’t overlook the water pump, which is crucial for circulating coolant; check for any leaks or signs of wear that could indicate a malfunction. Additionally, inspect the radiator cap, as a faulty cap can cause pressure issues and leaks. Pay attention to the heater core as well, especially if you notice damp carpets or a sweet smell inside the vehicle, which may signal a leak. If these initial checks do not reveal the source of the leak, consider performing a pressure test on the cooling system. This test can help you pinpoint the exact location of the leak, allowing for a more targeted repair. By following this diagnostic approach, you can effectively identify and resolve coolant leaks, ensuring your Ram 3500 runs smoothly.
When dealing with coolant leaks in a 2013 Ram 3500, it's essential to understand the common problems that may arise within the vehicle's cooling system. One of the primary culprits is a damaged radiator, which can develop cracks or corrosion over time, leading to leaks. Additionally, a faulty water pump can also be a significant source of coolant loss, as it is responsible for circulating coolant throughout the engine. Another frequent issue is the wear and tear of hoses connected to the cooling system; these hoses can become brittle and develop leaks. In more severe cases, a cracked engine block may be the source of the problem, which can lead to significant coolant loss and engine damage if not addressed promptly. Lastly, a faulty radiator cap can create pressure issues that result in coolant escaping from the system. Regular inspections and maintenance of these components can help prevent leaks and ensure your Ram 3500 operates efficiently. If you suspect a coolant leak, it's advisable to conduct a thorough check of these areas to identify and resolve the issue before it escalates.
Addressing a coolant leak in a 2013 Ram 3500 is of utmost urgency due to the significant risks associated with engine overheating. Coolant plays a vital role in maintaining optimal engine temperature, and a leak can quickly lead to a loss of coolant fluid, diminishing the engine's cooling capacity. If left unattended, this can result in the engine running excessively hot, which not only risks severe damage but can also lead to catastrophic engine failure, incurring costly repairs. Moreover, the safety of the vehicle is compromised when the engine overheats, potentially leading to dangerous situations on the road. Therefore, it is crucial for DIY enthusiasts to act swiftly upon noticing any signs of a coolant leak, as early intervention can prevent further damage and ensure the vehicle remains safe and reliable.
