How To Know If Your Lexus Radiator Has Malfunctioned

Let’s say you’re the proud owner of a Lexus from your premier local dealership and everything’s worked fine for many years. However, some parts can malfunction from time to time, and the radiator, which cools down your engine, is one of them. If you’re wondering how to tell if your Lexus radiator malfunctioned, here are some warning signs to look out for.

Radiator Leakage and Cracks

A tell-tale sign of malfunctioning radiators is if the coolant leaks out or escapes. To check if your radiator is leaking, drive out of your garage, then get out of your car and look at the garage floor. If there’s fluid on the floor, chances are your radiator is leaking.

Leaks are frequently caused by cracks in your radiator. Cracks can be caused by anything from minor bumps and collisions to erosion of the part of radiator that contained the coolant. To check for a crack on the radiator, look for the part that steam escapes from on your closed-up radiator. Pay special attention to radiator hoses in particular– those are the most likely places a crack can occur.

Radiator Blockage

If the cooling passages in your radiator get blocked, coolant will not flow through your engine efficiently, leading to a faulty radiator and engine overheating. Unfortunately, this issue’s harder to spot on your own– you might need to bring your vehicle to a professional. Since blocked passages in a radiator can be hard to repair, you may need to buy a new radiator, preferably from a reputable genuine Lexus parts supplier.

Radiator Corrosion

As time passes, rust might form on your radiator. Furthermore, whenever you drive a car with a rusty radiator, the movement can make rust fall off the inner walls into the coolant fluid. Over time, your coolant becomes thicker and darker in color, and eventually it won’t cool your engine.

If there isn’t too much rust, you can resolve this issue at home: first, drain dirty coolant from your radiator by opening its bleed valve. Then pour in a clean radiator rust flush solution, close the valve, and start your engine. This lets the solution heat up, breaking down rust. Next, rinse a few times with water until your radiator is clear. Finally, top up with new coolant.

Engine Overheating

This is the most classic sign of a malfunctioning radiator. if coolant isn’t circulating throughout your engine at the right temperature or quantity, your engine will overheat. Fortunately, most modern cars have a thermostat built into the engine, so you can check it to find the exact temperature of your coolant. If the temperature is too high, you’ll need to replace the coolant with a new one. Alternatively, if the thermostat is not functioning well, you might need to completely replace your radiator.
