Once you have sprayed enough water on the radiator, allow it to sit for a few minutes to loosen up any dirt or debris. This will make it easier to remove them during cleaning.
After dampening your RV rear radiator, you can apply an appropriate cleaner solution per the manufacturer’s instructions. This will help remove any remaining dirt or debris from your RV rear radiator leaving it clean and functioning optimally.
Step 03: Apply an Appropriate Radiator Cleaner Solution
Applying an appropriate cleaning solution is crucial when cleaning an RV rear radiator. This solution helps to break down and remove any stubborn dirt or debris stuck in the radiator’s fins.
There are several types of radiator cleaner solutions available on the market, so it’s important to choose one that is suitable for your RV’s specific make and model. Some cleaners are designed for aluminum radiators, while others are better suited for copper radiators.
Before applying the cleaner solution, it’s important to ensure the radiator is completely cool. You should also wear protective gloves and eyewear to prevent any potential harm from the chemicals in the cleaner.
You can use a spray bottle or a specialized applicator tool to apply the cleaner solution. Spray or apply the solution evenly over the radiator’s surface, covering all areas thoroughly.
Once you’ve applied the cleaner solution, let it sit for several minutes according to manufacturer instructions. This will allow it time to break down any dirt or debris that may be stuck in the radiator’s fins.
After letting it sit, rinse off the radiator with water using a hose or pressure washer. Be sure to rinse thoroughly to remove all traces of the cleaner solution.
Step 04: Leave the Cleaner Solution on for Some Time
After applying an appropriate radiator cleaner solution, it’s essential to let it sit for a while to allow it to break down any remaining debris and grime effectively. The exact amount of time needed will vary depending on the specific cleaner being used, so be sure to follow the instructions on the product label.
Most radiator cleaners generally require anywhere from 5-15 minutes of dwell time to work effectively. During this time, it’s best to avoid running the engine or exposing the radiator to any extreme temperatures or weather conditions.
While waiting for the cleaner solution to do its job, take a moment to inspect other areas of your RV’s cooling system for any signs of damage or leaks. This is also a good opportunity to double-check that all necessary parts have been removed and set aside safely.
After the recommended dwell time has passed, rinse off the radiator thoroughly with water. Use enough water pressure to get rid of the cleaner and any remaining debris between the fins.
Step 05: Rinse off with Water
After leaving the cleaner solution on the radiator fins for some time, it’s time to rinse it off with water. A hose or pressure washer can be used for this. Make sure to spray water from the back of the radiator towards the front so debris is flushed outwards and not inwards.
Ensure that all of the cleaner solutions are rinsed off properly, as any remaining solution may cause damage to your RV’s engine. Additionally, you should check for any remaining debris on the fins and repeat the cleaning process if necessary.
Step 06: Repeat If Necessary
If you notice debris still stuck in the fins after rinsing off the radiator, do not worry. It is common for some debris to be stubborn and require multiple cleaning attempts. Simply repeat the cleaning process until all debris has been removed from the RV rear radiator.
If you had to repeat the cleaning process, it might indicate that your RV’s cooling system needs attention. A dirty or clogged radiator can cause your engine to overheat and lead to costly repairs. Therefore, it is recommended to perform regular maintenance on your RV’s cooling system to prevent any potential issues.
