Coolant is the lifeblood of your radiator. This fluid runs through the system to cool the air that’s blown through the engine. A leaking radiator will leave your engine susceptible to overheating, which can make it much less efficient and eventually lead to a breakdown out on the road. All drivers should know the common signs of a radiator leak below so they can have it repaired before it creates an emergency.

Telltale Signs of a Radiator Leak

1. Coolant Puddles

Look at the ground beneath your car after it’s been parked for more than an hour. Pools of liquid may indicate leaks. Sometimes fluid may be visible under the vehicle from innocuous sources, such as condensation dripping from the air conditioning system. This will be transparent and odorless, however, while coolant smells sweet and will be colored. Green, red, orange, or blue are all common shades of coolant. 

2. Wet or Stained Radiator

Get underneath the engine with a flashlight to examine the underside of the radiator. Feel the unit for any wet spots indicating a leak. Dried leaks may have stained the radiator with rusty spots or white deposits. Only do this when the engine is cool or you may burn yourself.

3. Dropping Fluid Levels

Over time, fluid levels will lower. Your auto mechanic will refill your system with coolant when you bring it in for routine service. However, your vehicle shouldn’t experience a rapid or acute dip in fluid levels. Any unusual change in your coolant levels is a clear sign of a leak. Checking this is easy. The coolant reservoir is transparent, so you’ll be able to see it just by popping your hood and locating the “full” line on the reservoir.
