How to Troubleshoot Your Cadillac Deville Radiator

Your Cadillac Deville radiator is your main line of defense against overheating. As you drive, your engine heat builds up, and if its temperature gets too high, then it could be bad news for your engine. Good thing your radiator is there to ensure proper coolant flow and engine cooling. If this component malfunctions, then you're bound to see that overheat warning light on your dashboard blinking in no time. Keep in mind, though, that overheating can be caused by other components related to the radiator, so be sure to check them as well when diagnosing the root of your problem.

 

Low coolant levels

Having low levels of coolant is actually the most common cause of overheating. While your engine is cool, open the radiator cap and see if the radiator has enough fluid in it. If necessary, fill the radiator with a 50/50 mixture of water and coolant.

Leaking coolant

Make sure to check for any coolant leaking from outside the vehicle. If you notice a sweet smell or a green liquid puddle on the ground, then you might have a leaky radiator or hose. Seal or replace leaking components accordingly.

High temps at high speed

It's important for you to check your engine temp when you hit highway speeds. If your engine begins to overheat when you hit 55 miles per hour or more, then your coolant or water is not circulating properly. To check if coolant/water is circulating properly, start the engine with the radiator cap off. If the water pops over the top smoothly while still retaining its amount, then you're all good.

Faulty hoses

Hoses can become brittle or cracked over time, so be sure to check their condition after a while. Also check for leaks in the seams or in the fittings. If you spot damage, have these hoses replaced immediately.

Water pump leaks

If your thermostat is open and clear, then the water will be able to pass through it. However, if it is clean yet the water isn't circulating, then you might have a leak in the water pump.

As you cruise down the freeway, your engine generates massive amounts of heat, which, if not managed properly, could do more harm than good. Luckily you have a handy Cadillac Deville radiator plugged into your ride. Your radiator plays a huge role in keeping your engine cool, preventing overheating and engine damage. However, if you want to keep your radiator in fighting form for as long as possible, then you're going to have to properly maintain it. With proper care and maintenance, your radiator could last for at least eight to ten years. So be sure to follow these basic radiator-care tips.

Use proper coolant

Having a correct antifreeze coolant is instrumental so you may want to use glycol-based antifreeze, mixed with the prescribed amount of water. Also bear in mind not to use the antifreeze alone; make sure to mix it with water. By using the right coolant and mixture, you'll be able to properly maintain your radiator.

Flush out coolant

It's important that you flush out your ride's cooling system as often as your owner's manual suggests. Over time, your radiator will attract dirt that will hamper its performance; hence you must flush out your old coolant. This process is rather simple, and it involves draining and siphoning coolant from the system and reservoir, followed by refilling the system with new coolant. Replacing the coolant will guarantee that your water and antifreeze mixture continues to flow properly.

Replace the radiator cap

It's best to replace your radiator cap while you're already in the process of changing antifreeze coolant. As time passes, your radiator cap can become dry and damaged, allowing coolant to escape the cooling system. For this purpose alone, you should replace your radiator cap with a new one.

Inspect fittings and hoses

Through time, your hoses and fittings can lose their elasticity due to a loss in moisture. Hoses can also develop small holes due to pressure produced in the cooling system. If you notice small punctures or wear and tear on your fittings or hoses, then have them replaced right away.

Clean the radiator

Remove the radiator and clean it. Inspect it for rust or water calcification that can accumulate from within it.
