Replacing hood pad: worthwhile?? - Page 2 - PeachParts Mercedes-Benz Forum

They're relatively cheap -- about $30 bucks or so. Click on the fastlane tab above and look for it.

Remove your old one with a putty knife and some adhesive remover. Lay down a sheet or other cloth over your engine to protect it. Don't use plastic because the adhesive remover will eat right through it. Then spray the hood with some heavy duty 3M spray adhesive (#9?), then just slap that new pad right on and smooth out the kinks.

It's pretty tough to do it alone because you get one shot to throw it up -- doable though. Better to have an assistant help you "wallpaper" it up.

Good luck!

Hi Paul,
It turns out that FastLane doesn't ship to Europe

Know of any other good supplier that you know of?

Cheers!

Look on this website to buy the hood pad, or try Performance Parts.

If you don't replace it, you will begin to see a noticeable difference in the paint on your hood. The voice of experience speaks.

Vronsky,

Before I knew of this forum, I needed a hood pad ('87 SDL - diesels are loud). Found a company on Ebay, they always start their bids at $29. I just called them directly and ordered it, that is their standard price + about $8 shipping for me.

Get some of the heavy duty 3 M adhesive. It says "high heat made for hood pads" on it in the small print. It is about $15 a can in the US. One can was just enough, go for 2 if you are not sure.

I cleaned off the old pad with a scraper, then pressure washed the under hood, then wiped it down with a solvent to get rid of the oil / fuel residue.

Spray the adhesive on both parts, let then dry for a while, get some help aligning it and attaching.

MAJOR difference in noise in the diesel.

Good Luck!
Chuck

I glued mine back on using fabric spray glue (3M) which can be purchased at any fabric store. Works extremely well.

I'll be doing mine soon as the new pad came with the car. I searched #m's website and here's the part #. You can also order directly from them.

24 oz spray - $17.80
Aerosol contact adhesive designed for bonding vinyl tops, heavyweight liners and hood silencer pads where high strength and heat resistance are needed. Part number 08090.

8 oz spray - $7.55
Aerosol contact adhesive designed for bonding vinyl tops, heavyweight liners and hood silencer pads where high strength and heat resistance are needed. Part number 08091

I don't know which size would be needed though.

later!

Ron / Folks,

I believe the can I used was the 24 oz (it was about $15 at a Napa store). I did a criss-cross pattern as recommended on the 3m can, 3 times on the hood, 3 times on the pad. My patterns were 3-4" apart as I didn't think I could cover the entire pad. I made it 98% of the way, leaving just a couple areas unsprayed for the 3rd time. It is still stuck there and looks like day 1.

I recently replaced the hood liner on my '89 420 SEL. The new liner from the dealer was $55 and completely different from the original. The new one is a 3/4 thick foam with a honeycomb square pattern, whereas the original was just a cheap thin insulation. It actually looks a lot like those closed foam camping mattresses that roll up. I glued it with a tube of 3M weatherstrip adhesive which has held up just fine.

Replaced my pad with brand new -- it really looks nice. Got mine for about $68.00 + $15.00 for the 3M adhesive. I didn't use adhesive remover, the old pad scraped off pretty good with a putty knife. Besides, any residue wil be covered by the new pad. Also, I don't think you need to get 100% coverage with the adhesive. That stuff sticks VERY well. I think somewhere it was mentioned that one has a little time to "adjust" pad position once placed. All I can say is that I had NO time for adjustment -- once placed that was IT. Luckily, I had accurately placed alignment markers (tape and pen will do) so that it was perfectly aligned the first time, then did the wallpaper trick and smoothed out the pad as I moved along. A helper would definitely be recommended, tho' I did it myself by placing a scaffold across my engine bay. I purchased pad + adhesive from www.************************.

Good Luck!

An alternative method would be to remove the hood for easier access to the job.

Benzwood · #28 09-02-2002, 07:20 PM

I replaced mine recently, definitely worth it in my opinion. Really cleans up the appearance and no foam "dust" falling down all the time.

I bought an aftermarket from this web site, and used 3M Super Trim Adhesive. An 18 oz can was just the right amount.

Drape some old sheets over the engine compartment and windshield before you scrape off the old pad, it gets messy.

And put the sheets back before you spray the new adhesive. I got some dripping but no problems with overspray, it's more like "silly string" than spray paint.

By the way -- I didn't try to get all the old adhesive off... I figured I'd end up ruining my paint job with stray solvent or something. So I just used a dull putty knife to scrape away all the old foam. So far (several months and quite a few miles) I've had absolutely no problem with it sagging or pulling away.

I would definitely recommend a helper... I don't think I could have attached it as neatly without one. It was particularly tricky sliding it under the sheet metal along the bottom of the hood.

And oh yeah, I did make one gratuitous addition to the hood pad before assembly...

I called a local MB dealer. He explained that the 'short' pads are standard on petrol W124's, and the 'long' ones are standard on diesel engines. Long pads cost $48 here, incl. sales tax. Will get myself one soon.

Cheers!

I've replaced pads on two of my Benzes. I used a putty knife to remove the old pads. I removed as much as I could and didn't worry about the old adhesive. I used 3M contact cement on both the pads I replaced and have had no problems yet. The first pad I did was 4 years ago.

I bought a cheap 97 cent brush top spread the goop over both the hood and the pad let dry. Yes, you only get one try at lining up the pad. Do a dry fit first to see how the pad fits and how much may or may not get tucked into the front or back of the hood. Mark the centers with tape and start with the front or back, then stretch the pad to the other end and press it into place along the center, then work your way to the outsides.

Good Luck!
