5 Signs That Tell You Your Radiator Is Clogged

• Leaking coolant. When coolant is not able to circulate in the radiator, it can leak out onto other areas of the vehicle.
• Discolored and thicker coolant. You know your coolant's original color, don't you?
• Damaged water pump.
• Excessively high gauge temperature readings.
• Blocked, bent, or damaged radiator fins.

One may also ask, can a clogged radiator cause transmission problems? Yes, your radiator can clog causing you to have an over heated transmission, causing it to fail. Your radiator actually has a built in trans cooler. This is what I suspect clogged. And because there is no heat sensor on the transmission, or that part of your radiator, you would get no warning.

Subsequently, one may also ask, how do you unclog a radiator?

Remove the radiator fill cap and open the drain petcock. Allow the radiator fluid pass into the bucket that is already present. Get a water hose and put it inside the radiator fill cap to allow water inside vehicle's cooling system. Wait until the escaping water is clear and smoothly draining.
