Coolant Leak by Right Front Tire- (7 Proven Solution)

Are you experiencing some coolant leak on the passenger side tire? This is a serious issue that requires urgent attention. The leaks can create hazardous conditions for your car’s engine. Without the correct amount of coolant, your engine could overheat.  

Because the coolant plays such a huge role in how well your engine runs, this article will discuss the causes of coolant leaks by the right front tire and offer a solution to each.

Coolant Leak by Right Front Tire: Causes & Solutions

Leaking Heater Core

The most typical reason why coolant leaks is a broken or leaking heater core. This is a common issue, especially if the system has red “Dex-Cool” antifreeze. Although the coolant is advertised to have a lifetime lifespan, it should be replaced every three years.

The coolant’s ingredients will wear out in two years, much as other antifreeze on the market. If that occurs, acids will build in the system and attack the metal components.


Get a mechanic to check the heater core of your vehicle for leaks. It must be replaced if it is leaking to fix the problem permanently.

Leaking Rubber Hoses

Radiator and heater hoses are also found in the cooling system area. The coolant fluid will spill close to the passenger side if these coolant hoses crack or become damaged.


Changing the radiator or coolant hoses is not tricky. To replace the hoses, just adhere to the detailed instructions below.

Before starting the replacement procedure, you must park your vehicle on a flat surface and turn off its engine. Give the radiator cap some minutes to cool. The radiator cap should then be unplugged and left aside. 

  • Put an oil drain pan under the radiator and unhook the drain petcock to drain the radiator.
  • The clamps on the radiator hose’s ends should be unscrewed. The two main types of hose clamps are spring tension and screw design. To unscrew the spring tension-type, you must either pull it back or squeeze it using pliers. On the other hand, all you have to do is use the screwdriver to loosen the screw tension.
  • After releasing the clamps, twist the coolant line to free it from the fitting and pull it out.
  • Attach the new coolant hose to the connector and place the hose clamps.  Then, tighten the clamps until they are at least a quarter inch away from the radiator hose’s end. Ensure the clamps are past the connector’s bead and tightly fastened.
  • The down radiator hose can also be unscrewed using the same procedures, and they can be changed if necessary.
  • Replace the drain petcock and add fresh coolant to the cooling system.
  • Every time you service the cooling system, remember to bleed it. It’s simple to bleed the system. Just keep the radiator top off and run the engine. Run your engine until it reaches the operating temperature and the antifreeze begins to leak from the radiator.
  • Lastly, top up the reservoir and radiator with coolant.

A Defective Heating Control Valve

Coolant leaking by the front right tire of your car is a problem that a broken heating control valve may also cause. The heating control valve begins to deteriorate or shatter over time. As a result, the control valve releases coolant.


If the heating control valve malfunctions or becomes worn out, you must replace it to prevent coolant leakage. Visit your nearest repair shop to have the valve replaced by a mechanic.

A Faulty Water Pump

A malfunctioning water pump can also cause coolant to leak from the axle sealing or any gasket. The water pump includes gaskets to guarantee that the antifreeze will remain shut, ensuring continual water flow.

The water pump’s gaskets wear or get damaged over time, which leads to coolant leaks.  The water pump is to blame if you ever see a pool of coolant or water beneath the car’s front end.


Anytime you discover a problem with the water pump, you should immediately replace it. This repair is not easy, so it would be better for you to take the car to a mechanic. This will cost you more than $500.

Cracked Coolant Split Pipe

The coolant can also spill out of a cracked coolant pipe. Even a tiny hairline crack on a coolant split pipe will cause the antifreeze to spill. Just check the hoses leading from your vehicle’s coolant reservoir to the front. You will see plastic fitting in the shape of a Y is known as a coolant split pipe.


This is a typical flaw that is simple to resolve. Simply swap out the damaged pipe for the ECS aluminum version. And you shouldn’t ever touch it or look back.

Leaking Coolant Reservoir

Sometimes the problem is with the coolant reservoir itself. Due to aging or overheating, the coolant reservoir eventually cracks or breaks. As a result, the coolant reservoir will experience coolant leakage.


You should swap out the damaged coolant reservoir for a new one to prevent the coolant from leaking out. You can get assistance from a mechanic if you don’t know how to change the coolant reservoir.

A Faulty Radiator

Another frequent reason for coolant leaks is a broken radiator. The radiator is more likely to leak if it has a plastic tank on the bottom and top. In most cases, the radiator’s plastic portion disassembles from the metal portion. When this happens, the coolant will drain down through the metal portion of the radiator and create a pool at its base.

The coolant will spill to your vehicle’s right side if the leak worsens. It’s also the cause of the puddle next to the front right tire. Grab a flashlight to locate the leak in the radiator region.


There is only one remedy to this issue; to replace the damaged or leaking radiator with a new one. Since this task can be tricky,  you should take your vehicle to a licensed mechanic to acquire a replacement.
