Maintenance & Repairs

I’ve been having some issues with my vehicle’s third brake light gasket. I noticed water leaking into the trunk, and it’s likely caused by a failing or old gasket. I’m looking for advice on how to properly replace it.

What to Look For

Before diving in, here are a few things I think we should consider:

  • Compatibility: Make sure the gasket fits your specific vehicle model.
  • Material Quality: What should I be looking for? Rubber or silicone? I’ve read conflicting advice about durability and sealing effectiveness.
  • Installation Steps: What’s the best method? Does it require any special tools or adhesives?

I’ve replaced my third brake light gasket recently, and I found that using a silicone sealant really helped create a better seal. Make sure to clean the surface well before applying it!

That’s a great tip! I always use a rubber gasket instead. It seems to last longer in harsh weather!

4

Good to know about the rubber option! For installation, I usually warm up the gasket slightly before installing it. It helps it conform better to the shape.

5

Sounds interesting! Is there a specific method you use to warm it up? Just curious!

6

I just leave it in the sun for a bit or use a hairdryer on low. Just be careful not to overheat it!

I’ve never thought about warming it up! I usually just press it down firmly and hope for the best. Sometimes it works, sometimes it doesn’t. Haha!

Haha! That’s a relatable approach! But I think being thorough with the prep work can prevent leaks in the long run.

Absolutely! Cleaning the surface is key. If there’s old adhesive left, it won’t seal right. I usually use some acetone for that.

10

That’s what I do as well! Speaking of which, how long do you all wait before testing the light after installation?

I usually give it at least an hour to cure, just to be safe. Better to be patient than deal with leaks later!

Totally agree! Patience saves us from extra work. I’ve been there before—thought I could rush it and got a nice leak as a result.

13

It’s easy to make that mistake! I’m actually thinking of replacing my gasket soon. Any brand recommendations?

14

I usually go for OEM parts when I can. They tend to fit better and last longer than aftermarket ones.

I guess it makes sense to invest in quality. OEM it is then! I just hope I don’t accidentally end up with a cheap knock-off.

Oh, the horror! The last time I tried that, my brake light was flickering like a disco ball.

17

Haha! That sounds like a wild party! But in all seriousness, a good seal is worth it to avoid those kinds of surprises.

It’s true! A solid gasket saves us from potential headaches. Just take your time and follow the best practices we’ve discussed.

I’ve replaced my third brake light gasket before. I used silicone, and it’s held up really well against the weather. Highly recommend it for durability!

That’s awesome! I’ve heard foam can get squished easily, but it’s lightweight. Do you think it affects safety?
