Mine just started rattling, crawled under there today and noticed it was a heat shield so I just got back in so I could make it to work on time. I plan to get under there in the morning and rip that thing off.
I have a feeling they are not replaceable. The original ones probably don't even "bolt on" but instead are a permanent part of the cat. Just curious, why do you even want a heat shield on it? If you want to prolong the life of the current one just get a clothes hanger or some sort of similar wire and wrap it around it tight to stop it from rattling.
I was afraid it may not be (easily) replaceable, it looks like you can get the shields according to the following schematic and if the part numbers are right the sheilds are only be about $14 from that dealer ( Nissan Parts | OEM Nissan Parts | Genuine OEM Parts ). I wanted to keep them to prevent fires when I'm off-roading from brush/grass:
I e-mailed that dealer a photo of my shields to get the exact part numbers and ask if they are replaceable. Here is the photo that I took (shield circled in red):
Not from the response I just received from that dealer. They had a tech crawl under one of the 1st gens they had on the lot and unfortunately, they believe that it is fixed to the cat section of the exhaust and the pricing is rather phenomenal.
Right side = $800.77
Left side = $382.86
So, I may try cleaning mine up and re-attaching that seam somehow.
- The diagram you posted highlights the primary cats
- The picture you posted is a secondary cat
- The primary cats have removable heat shields (assuming our good friend Mr. Rust hasn't seized the bolts)
- The secondary cats are a single unit from flange to flange (stamped, welded, etc.etc.)
- Replacing the shields on the primary cats might require you to dismantle a fair amount of your forward exhaust system, there's not a lot of space to wiggle stuff in and out up there.
- Which heat shield do you want to replace?
- What kind of hallucinogen is that dealership taking, because those prices are friggin ridiculous :laugh:
- Why not ditch the secondary cats and put some walker pipes on there?
I'm currently designing a build of my 02 CC LB V6 4x4 as an overlander, with dreams of surfing and exploring all over North America for the next few years, and maybe some global travel afterward. I had a coming to Jesus moment today when I realized that the difference between the Curb...
Story goes as follows : I found a 1 owner 2000 Frontier crew cab 4wd with a good host of options , 280,000 miles and in pretty decent condition inside and out for sale and i wanted it , guy said the engine was replaced by the Nissan dealer at just over 100,000 miles when it self destructed...
I heard some weird sounds form my truck, it sounded like rod knock. I checked cyl 1, it seemed ok. I checked cyl 2, there was significant play. I suspect oil starvation a few months ago caused excessive wear to the rod bearing(s). I'm looking at my options now.
1. take the oil pan off and see...
