Coolant leaks are one of those common issues that can happen to a vehicle anytime, if the cooling system gets damaged anywhere for some reason. Though in most of the times coolant leakage can be easily found, at times if the leakage happens internally, it might not be apparently visible to us.
Usually coolant leakage can be seen if it drips, seeps,spraysor, bubbles out from the damaged component. But whether it is visible or not, the most dangerous symptom of coolant leakage is engine overheating.
How a Coolant Leakage is Repaired
The diagnosis of the place and cause of the coolant leakage is the first step taken towards fixing this issue. The mechanics of the Cadillac service near Watsonville, explained that repairing the component that is causing the coolant leakage is the only way to solve the issue. So, one should know what are the places from where the coolant can leak, and what are the reasons that might have caused the damage.
Some modern day car come with a Low Coolant indicator lamp that turns on whenever your car cooling system lacks the right amount of coolant in the tank. If the lamp turns on even after a recent coolant top up, it is a sure sign of coolant leakage.
The only way to confirm, is to open the hood and inspect the engine as well as the cooling system visually to look for any sign of liquid spilling out of the engine, radiator or the hoses. Usually the car coolants come in bright colors like green, yellow or orange depending upon the type of antifreeze is installed in your car cooling system.
To look for a coolant leakage, you also need to see below your car, where you can see the same colored liquid dripping down from the undercarriage of your car.
The other sign of coolant leakage can be diagnosed sometimes by a sweet smell, or through the odor of antifreeze that is made of ethylene glycol.
A bad shaft seal of the car water pump can allow the coolant to dribble out of its vent. The damaged gasket or the O-ring that seals up the water pump to the engine front cover can cause leakage of the coolant. Replacing the gasket or the O ring will automatically stop the coolant from leaking out.
Bad radiators can cause leakage around the upper or lower hose connections when there is excessive vibration in the vehicle. On radiators made of copper/brass, leakages occur typically from where the cooling tubes stay connected to the core headers. Internal corrosion can cause the coolant leak if it has gone old and has never been changed.
Other damaged parts of the vehicle that can cause the coolant leak are the hoses, freeze plugs, heater core, intake manifold gasket.
But if there is an internal coolant leakage, the entire course of repair needs to be done only under a trained group of mechanics, warned the mechanics of the Watsonville Cadillac service department.
