Nissan Pickup Radiator

Signs of a Nissan Pickup Radiator Going Bad

Radiator problems are fairly common for the Nissan Pickup. The common approach as far as a repair goes is flushing the fluid out and refilling it with new one. However, this won't always work especially with a problematic radiator such as that of the Pickup's. That's why it's important to be aware of the symptoms that tell you need to replace your stock radiator with a new one. Here are some of the common signs:

Rusty radiator fluid

When you flush the fluid out of the radiator and you notice that its color is brownish and rustic, this is a sign that the stock unit is in need of replacement. The rust comes from the wear and tear the part has accumulated overtime. There's not much you can do if the insides are slowly being flushed away with the fluid. As the truck ages, the radiator rusts even more.

Whistling sound

Hearing a mild whistling sound somewhere behind the truck's glove compartment with the air conditioner on is also an indicator of a radiator slowly going bad. To be specific, there is a leak somewhere in the heater core that's responsible for giving off the sound. An added symptom is some water entering the passenger cabin accompanies that sound.

Excessive fan play

The fan of the Nissan Pickup radiator should stay secure at all times. However, too much play on the part-which could escalate to fallen and torn blades-is a problem that needs immediate attention. The clutch of the pulley and fan may also be loose. You should start replacing these parts to ensure cooling efficiency.

No overflow

Radiator fluid should circulate around the engine, through the heater core, hoses, and overflow. If there's no liquid inside the reservoir tank, this is a sign of a bad thermostat that's not making accurate readings. Replace this at once to return coolant flow.

Easy overheating

An engine easily overheating, regardless of speed, is an obvious sign that the Nissan Pickup has a restricted radiator. By this time, there's not much you can do with the existing unit but replace it with a new one as well.

  • Four Nissan Pickup Radiator Upkeep Tips 27 February 2013

    What makes the Nissan Pickup great is that it's a perfect vehicle for various heavy-duty jobs. However, this pushes its radiator to its limit. With too much heat going around under the hood, you might end up with a struggling engine that could die on you in the middle of a drive. Overheating is a problem you'd want to avoid at all costs. That's why you should make sure that the cooling system is in good condition to do its job. The following are some maintenance tips you can do on your Nissan Pickup radiator.


    Perform mandatory pressure tests.


    The different liquids can travel through the radiator and the rest of the truck's cooling system because of the pressure that pushes it around. Performing mandatory tests can show you the earliest signs of a drop in pressure before it's too late. If too much is lost overtime, the truck's engine won't be cooled enough to run properly and could overheat.


    Check the cap and hoses.


    Keeping the radiator in good condition also means keeping its parts and accessories intact. One thing you should check is the cap that keeps fluids inside at all times. A loose cover results to a decrease in pressure and the release of coolant. Other than the cap, inspect the hoses that run to and from the radiator. Torn or cracked ones are also an avenue for escape for the fluid.


    Flush the fluid and coolant.


    You should flush the fluid inside the Nissan Pickup radiator at least once every two years. Do so every year if the truck is more than five years old. Removing the liquid is a way to get rid of any accumulated dirt and metal particles from the insides of the radiator. This results to an improvement in cooling efficiency and an extension in the service life of the part.


    Refill with enough coolant.


    Refilling the radiator with new coolant is not as easy as opening a bottle and pouring the contents in. You should be aware of how much antifreeze and water you use. The default ratio is a half-and-half portion of both. If you live in very hot or cold weather, the ratio must change with the conditions.
