A Volvo radiator leak is a serious problem. While most would only keep replenishing coolant as a fast solution, this problem should not be ignored too long.
The radiator has one of the most vital roles in keeping the engine at an optimal temperature. Having a leak could cause more problems in the engine if left unmanaged. Take a look at these signs of a leaking radiator so you can deal with the issue right away:
An obvious sign of a Volvo radiator leak is seeing a puddle of coolant below the car. To check whether the puddle is a coolant or just a plain water condensation, look and examine it closely. If you can see a green, yellow, or a blue tinge, then it will usually be a coolant. It will also feel greasy and will have a sweet smell.
The Volvo radiator is made up of long tubes, a header, tanks, and fins that are made out of metal and copper. These materials will react with heat, vibrations, impacts, and corrosions. If rust has developed inside the radiator, it will be more prone to developing holes. Pay particular attention to every angle of the radiator so you can inspect for a discoloration that may be rust. Aluminium radiators that do not rust may also corrode in some places and will also develop pinhole leaks.
Holes on the Hoses and Tubes
Dripping coolant may not come from the radiator itself but from the radiator hoses and tubes that run from the radiator to the engine. Since these components serve as a pathway for the coolant, there is a chance that the puddles of coolant seeped out from their holes. You may check for discolorations or active dripping from these parts.
Inspect With a Running Engine
In some instances, any leak will occur only while the engine is running and hot while the system is pressurized. You have to warm up the vehicle and do the inspection once it has reached its operating temperature.
How to Inspect for Leaks
Finding a leak from its source can be difficult especially while the engine is running. The Volvo radiator and other parts can get too hot and will cause serious burn injuries. Protective clothing must be worn before you go around looking for leaks.
Take note also that a pressurized leak may cause the radiator to spray out unexpectedly. You must avoid any liquid or coolant from directly hitting you in the eye. It is advised to wear safety glasses while doing the inspection.
What to Do With a Leaking Radiator There are holes that may be fixed with commercial epoxy and there are those that needed to be welded. A radiator leak may also be fixed temporarily using radiator stop-leak products. Remember that this is not the best solution and is only recommended if you cannot get to a mechanic right away. Getting a permanent solution from a reputable mechanic is crucial as you need to ensure that the leak will be repaired and will not happen again anytime soon.
