Dodge Ram 2500 Ac Condenser

Common Symptoms of Dodge Ram 2500 AC Condenser

Keeping the pickup truck's interior cool and comfy, especially during summer, is made possible with a fully functional air conditioning system. But, at times, the cooling system may go kaput, and you might need to replace the parts like the condenser or the evaporator. If you think your cooling system is already defective, then you had better perform some troubleshooting. Listed below are just some of the symptoms that will help you tell if your vehicle has a broken AC condenser as well as the reasons behind them.

Leaking refrigerant

Check for the compressor's clutch and examine if it is not turning. If it doesn't, then you should inspect the condenser, evaporator, compressor, and the hoses for signs of an oily residue. This oil is an indicator of leaking refrigerant in the car's cooling system. This leakage is usually a result of faulty seals and hoses. In other instances, the leaks are caused by pressure buildup. If this is the case, then you will notice that the system becomes warmer even if it cools initially. If you want to make diagnosis faster than usual, you may buy a refrigerant leak detector at your local auto supply store.

Unusual compressor noise

A defective AC condenser unit may manifest itself through a rattling noise. This grumbling noise is caused by an oil break down, which causes friction from bits of metal inside the AC unit. These metal bits, in turn, cause blockage to the condenser and result to an unusual AC compressor noise.

Automatic shutoff

Clunking sounds from the AC unit may be attributed to a low system pressure caused by contaminants in the condenser. Sometimes, sludge or other contaminants may also block the lines, expansion valve, evaporator, or the orifice tube. This clunking sound occurs because of the vehicle's automatic shutoff feature, which results from a lower than normal pressure in the system.

Faulty fuses

A malfunctioning AC condenser unit may be caused by blown fuses. So don't forget to inspect the fuses under the dashboard panel for any signs of damage. Faulty fuses make the compressor inadequately lubricated because blown fuses disrupt the condenser's function to allow oil to lubricate the compressor.

  • Ways to Keep your Dodge Ram 2500 AC Condenser in Good Condition 27 February 2013

    The auto's condenser unit is a crucial part of the cooling system because it collects filth and oil out of the refrigerant from the AC compressor. It keeps the sludge out of the valves and tubes to prevent damage to the cooling unit. Overtime, this AC condenser will fail because of poor maintenance, or it may have simply exceeded its service life. If you want to keep your Dodge Ram 2500 AC condenser in its best condition for a long period of time, then follow these maintenance tips:


    Schedule a regular flushing of the AC unit.


    To prevent premature replacement of the parts in the AC unit like the condenser, accumulator, or expansion valve, maintain a schedule of flushing the unit. You see, sludge and contaminant buildup is the main cause of repeated compressor failure and AC system blockages. When left not flushed, the AC compressor unit can accumulate a lot of metallic debris, which is mostly collected in the condenser. This can greatly impede cooling performance, so it is advised to regularly flush the system. In addition, be sure to use only approved flushing chemicals to clean the system. Doing otherwise may even decrease the unit's service life. Luckily, it's a good thing that regular flushing of the unit is a practical and economical alternative of replacing the condenser, accumulator, or other AC unit parts.


    Know when to inspect the AC unit.


    Experts suggest that the best time to do a car's AC unit inspection is during springtime. When performing inspection, always check the level of refrigerant. Additionally, check for any leaks to prevent the level from decreasing and affecting your AC unit. Also check for bubbles, cracks, leaks, or hardening on the hoses. Once done, do not forget to check the compressor drive belt's tension as it can also affect the cooling performance of the AC condenser unit.


    Maintain coolant pressure.


    Maintaining coolant pressure is done by running the AC unit at least once a month for ten minutes. This preventive maintenance keeps the hoses and seals from failing, in order to prevent damage to the AC condenser. Take note to turn the unit to its coolest setting and at highest fan speed for optimum results.


    Other maintenance tips

    Once done with flushing, applying a filter to the condenser can help evacuate the system better.
