Hood pad - heat shield or no?

Well, my hood pad gave up on me tonight.

Looking at Fastlane, there are 2 replacement options - with and without heat shield, but no pics to compare. How do I know which one I need.

Also, what do I need to do to replace it? Certainly scrape the old stuff off (take the hood off I assume? Then just use decal or trim adhesive and stick it on?

Thanks!

I believe the heat shield version is for turbocharged cars.

3m makes a hi heat adhesive in a spray can, Seriously, read and follow the directions on the can.

I removed the hood used a piece of 4 inch pipe to roll on the hood pad to assure positive grip. Still holding on after many years.

Whether you need the heat pad or not, the version with the heat pad is of much better quality and worth the additional cost.

I would not remove the hood. Aligning the hinges can be baffleling to a person not experienced with that task. I would lay an old blanket over the engine compartment and take a plastic ice scraper and scrape off the old pad, then take the adhesive recommended and spray both surfaces and very carefully apply the pad. Start in the center and work your way out. It is contact cement so heavy contact is not essential for good grip.

I just replaced my pad on a 300SD. After scraping/vacuuming the old disintegrated hood pad off, I used adhesive remover and a plastic putty knife to remove old adhesive. Several have commented that removing the old glue wasn't necessary.

Use the 3M adhesive for heavy duty/high heat application, 3M 8090 Super Trim. One can will just barely do it. I cut my pad in half from front to back and applied it in two sections with the hood in the straight up position. Not too bad a job.

At the risk of being repetitive, here are a few recommendations:

Cover the entire front end of the car (engine compartment & fenders) with a plastic, disposable drop cloth.
Use 3M adhesive remover to get the old adhesive off. Plan on the removal process taking several hours if you want to do a good job.
Lay the new pad flat for a while if it has been stored rolled up.
Test fit the new pad before applying the adhesive.
Use 3M 8090 adhesive. Do not even think about using anything else.
Position the hood in the "straight up" position for the final installation.
Enlist the help of at least one person for the installation.

This has been done to death in other threads, but I agree, use the 3M spray product specifically designed for hood pads - not the 77 crap or whatever else comes in a can. Ask at a real auto parts store if you aren't sure which one. Yes, the hood pad for the turbo model is worth the extra expense. No, you don't have to get your hood surgically clean for the new pad to stick properly, just make sure most of the old crap is off and that you follow the instructions for the glue. Good luck.

To remove and quickly realign the hood...

BEFORE unbolting anything, clean the hinges and place a strip of masking tape across the hinge onto the hood (side lip.) Then, with a marker, carefully draw a line "X" or whatever mark will be easily recognized, on the tape. Carefully with a razor, cut the tape perpendicular to the line so that half of the tape will remain on the hood and half on the hinge. You can then clean and sand off the old glue while the hood is on sawhorses, etc. Use the same tape trick to line up the new hood pad. When you spray on the new glue use 3M high strength, high temp you can leave it on inverted overnight - no sags.

Realignment is quick and easy as long as you have not removed any of the tape.

Good plan.

Thanks.

( I still would not remove the hood for the pad though.)
