Nissan Maxima Radiator

Signs That Your Nissan Maxima Radiator Is in Trouble

One of the most important parts of your vehicle's engine cooling system is the radiator. Without it, the other components under the hood including the pistons, cylinders, valves, and engine head would melt in an instant because too much heat. Your Nissan Maxima's radiator works under a lot of pressure and friction that could cause heat and result to problems. These radiator problems, should they occur, must not be taken for granted. Too much heat can seize the engine and cause an irreparable damage. To avoid getting your engine ruined beyond repair, take note of the following problems to watch out for in your Nissan Maxima's radiator.


Another sign of failure to watch out for in your Nissan Maxima's radiator is overheating. If the temperature of your car's engine rises above the normal temperature, this is a sure sign that your engine is hotter than it's supposed to be and this could lead to irreparable damages when ignored. Anything that prevents the cooling system's ability to absorb, transport, and dissipate heat can lead to overheating. Watch out for the main causes of overheating such as accumulated deposits in the water jackets that can lead to poor heat conductivity inside the engine, a water pump impeller that's eroded or loose, a damaged radiator cap, a faulty thermostat, poor airflow in the radiator, low level or loss of coolant, a slipping fan clutch, a lower radiator hose that has collapsed, or a failing electric cooling fan.

Heater failure

If you notice that your Nissan Maxima's heater suddenly starts blowing cold air, this could mean that your cooling system including the radiator is experiencing problems. Cold air blowing from the heater is a sign that the hot coolant from the engine has stopped circulating through the heater core. This failure in the heater could be the result of low coolant or other problems.

Leaking coolant

If you have spotted orange or green coolants leaked out in the passenger compartment of your Nissan Maxima, this is an obvious sign that your radiator is in trouble. Puddles and stains of green and orange coolants on the radiator or engine and a strong coolant smell emanating from the engine compartment are also sure warning signs that your radiator needs a replacement or a repair. These leaks could indicate punctures, corrosion, and other forms of damage in your vehicle's radiator. They could also indicate deteriorated radiator or heater hoses, failure in the engine gasket, or corrosion in the heater core.

  • Helpful Tips in Keeping Your Nissan Maxima Radiator in Good Condition

    Your Nissan Maxima's radiator is what prevents your car's engine and other parts from overheating. This is one of the components in your car that works under a lot of friction and pressure that can get damaged overtime by the build-up of harsh elements such as rust and calcium. When left unchecked, your radiator might encounter problems that will drastically affect its performance and cause serious and irreparable damage to the engine. To avoid this, here are a few tips that will help you keep your Nissan Maxima's radiator in good condition.

    Test the thermostat.

    A thermostat that has been damaged by severe overheating will affect the radiator's overall performance. Make sure that your thermostat is at its top condition by having it tested. You can test your car's thermostat for overheating problems by feeling the upper radiator hose or by using an infrared noncontact thermometer to read its temperature. The thermostat should open and hose should not feel uncomfortably hot. You may also dip the hose into boiling water and check the thermostat's exact opening temperature with a thermometer. If the test shows that your thermostat needs to be replaced, make sure to install one that has the same temperature rating as the original.

    Clean the radiator to avoid clogging.

    Aside from leaks, internal and external clogging is one of the most common problems that radiators encounter. This problem usually occurs when harsh elements such as dirt, debris, and bugs prevent the air from flowing through the core, making it hard for the radiator to dissipate heat. If you notice internal corrosion and an accumulation of deposits, remove your radiator immediately for cleaning or replacement. Remove the rust, dirt, grime, and hard water scale by using a chemical cleaner. You may also try backflushing the cooling system as it can also help in opening up your Nissan Maxima's clogged radiator.

    Refill the cooling system completely.

    If you're going to refill your car's cooling system, make sure that it's completely full to avoid air pockets in the heads, the heater core, and under the thermostat. These air pockets have the tendency to interfere with the cooling process and proper coolant circulation. If the cooling system of your Nissan Maxima does not have bleeder valves to vent air, loosening a heater hose temporarily will help get all the air out of the system.
