Even semi truck mechanics in Duncan, OK can find a coolant system leak maddening. There are plenty of possibilities of where leaks can come from and finding them is essential to a successful repair. Leaks also indicate areas where maintenance or replacements are required, which is another reason why you want your mechanic to locate them accurately. Here are six places most common for coolant leaks:
- Radiator: The most serious spot to find a coolant leak is the radiator. This is a major part of the coolant system, and if it fails, your entire system is basically useless. Radiators may leak in their main construction, but also where hoses connect. A corroded or rusty radiator needs to be replaced immediately. A proper diagnosis of leaks on or near your radiator can help determine if you need new hose connections or a new radiator.
- Water pump: Water pumps develop worn seals or may form leaks around the gasket. Mainly, the rubber or plastic parts in a water pump may wear out first, and if the water pump has not been replaced lately, that is likely the culprit. Unfortunately, it is not always possible to replace these seals in isolation, so you will likely need a new water pump.
- Hoses: It is important to check the condition of hoses regularly, as they may crack, develop pinholes or even break. The connections can corrode and lead to leaks, as well. Hoses are essential parts of the coolant system that are very vulnerable, too. Finding leaks on them is not uncommon, but fortunately, they are one of the easier, less expensive repairs when it comes to coolant systems.
- Heater core: Located inside the heating ventilation system near the HVAC unit, the heater core is out of sight and you are unlikely to notice if there are any leaks there. If it does leak, you may find coolant accumulate on the passenger side of your vehicle. Otherwise, it will most likely drip within your engine compartment. Sometimes, this is from a hose or connection being compromised, but other times, the core itself needs to be replaced.
- Intake manifold gasket: This part does not leak coolant frequently with semi trucks. If it does leak, coolant accumulates in the intake port, crankcase or on the outside of the engine. Fortunately, this type of leak is normally limited to certain brands of passenger vehicles, although it is possible for semi trucks.
- Freeze plugs: These are located in the engine block or cylinder head. They can corrode from the inside out, so it can be difficult to see if they are compromised until they are almost gone. Leaking coolant is one sign that the freeze plugs are losing integrity.
