Radiator Problem Symptoms
Your vehicle’s radiator is the heart of the cooling system that keep it running. The radiator fluid pulls the immense heat from the engine by circulating water and cool air from outside the system. Without a radiator, or with a broken one, your engine will overheat and pistons would break.
This can and will cause catastrophic damage to your vehicle. It is absolutely critical for the life of your vehicle to repair a broken radiator immediately. Not all radiator problems are obvious, so use these symptoms to know when it might be going out.
One of the easiest symptoms to spot is a radiator leak. If you see a puddle under your vehicle that’s either green or red and is slimy you’ve likely got a radiator leak. Radiator fluid is toxic and will harm animals or people, so it’s important to get leaks cleaned up. A radiator leak can lead to serious damage to your engine.
Another common symptom of a bad radiator is your vehicle overheats. Even if the overheating is only minor it is a huge sign that something isn’t right with your vehicle’s engine cooling system. In most cases issues turns out to be a minor leak, but can cause major damage.
Loss in Pressure
Radiators are designed by your vehicle’s manufacturer to run at a certain pressure. Generally, the pressure should be between 10 to 12 PSI. Radiators that have excessive corrosion will have lower pressure levels and should be serviced immediately. Owners can check the pressure level with gauges that fit over where the radiator cap goes.
Rust On The Radiator
It’s hard to see what’s going on inside your radiator and it’s components, but you can watch for signs of rust. If you see rust on the radiator, around it, or near it’s hoses you should take those signs serious. It is a clear indication you’ve got leaks or might have lower pressure.
Coolant Levels Low
When your radiator, hoses, or other components of your vehicle’s engine cooling system leak, it puts your coolant level low. While coolant does deplete naturally over time sudden drops are a symptom that something is wrong. Pop the hood and check your hoses and connections to look for leaks. If those areas are good the system could have another leak hidden somewhere.
Radiator & Coolant System Flush
Radiator flushes are need to make sure the cooling system is running efficiently, as it eliminates the rust, dirt and other various particles that can build up in your radiator. If your radiator fluid is a 50/50 mix of antifreeze and distilled water and becomes contaminated, it will prevent your engine from cooling efficiently while running. Running an engine that has contaminated fluid in the radiator can result in a cracked block or head.
Furthermore, if your engine coolant is not changed on time, it can start losing its capabilities of anti corrosion, which can end up deteriorating the metals the engine is made of including, copper, steel, aluminum and more. Corrosion and scale buildup can clog radiators, water pumps and even build up inside the heater core.
