Replacing Battery And Propane Vents

General Maintenance of Your RV - Replacing The Battery Box Vent and Propane Compartment Vents

Cracked Vent

As your RV gets older and it is exposed to the elements some of the plastic just cracks and need to be replaced.


This was the case with two of my three vents.


I have one for each propane tank and one for the batteries. They are often referred to as Battery Box Vents.


This is a pretty easy job and can be done in less then half an hour.



Stuff needed for this job:

• Philips Screw driver
• Flat Screw driver
• Caulking gun
• Caulking
• Paper Towel
• Spray Nine cleaner or Windex

Cleaned up vent hole on trailer

New Battery Box Vent in Place.

Remove the four screws holding the vent in place and put to the side. You will need them again.


If the vent does not come off, grab the flat screw driver and from the side give it a gentle tap and it will fall off.

Remove any excess old caulking. I found that the flat screw driver works well, just gently scrap it off or use a plastic scraper of some kind.

Clean off with cleaner and paper towel. Let it dry.


In the meantime, turn the new vent upside down and put a bead of caulking close to the outside edge and completely around the four holes.

Install the vent and as you tighten the screws up the caulking will ooze out on the sides.





Make sure not to tighten it to much. The plastic will crack.

You can clean up the excess caulking or leave it, your choice.

Cheers,
