What is the current best approach for removing the "hood liner" (foam sound insulation) from the underside of the hood on the 944s? I was able to quickly remove the foam layer using a plastic scraper. Now the underside of my hood is covered with a lovely layer of plastic adhesive.

This is starting to remind me of removing the plastic stone guards. For that job I used a hair dryer to remove the outer plastic layer then "sticker remover" (spray chemical) to get off the plastic adhesive.

Once it's off, should I consider replacing it? I'm not interested in concours, so originality isn't important. I'm more interested in any functional/performance effect.

Thanks,
MDW

 

Use the 3M adhesive remover that you spray on. Auto stores have it.

The later 944s didn't have that liner installed .... not sure the year they stopped but by '88 anyway for 951s. There have been discussions on why, I vote that the liner keeps too much heat in the engine bay at idle or slow speeds because the hood can't act like a heat sink. And weight, and cost. There is no adverse effect to hood paint if you leave it off other than cooking bird turds on pretty good.

 

I plan on removing mine. Mean while it is removing itself a little at a time.

Removing the adhesive is a simple job, just tedious.

Good luck.

 

you can also use NAPTHA without damaging the paint.

 

I used a shop-vac to take all the foam off. Then used a heat gun to melt and remove the glue. It took under 3 hours with no chemicals.

I use my head. Hold your hood up with your head ( failed hood shocks), and this stuff will crumble off nicely into your hair. Prop hood open with a broomstick, then move your head all around. Shower/shampoo as needed. Should be done in no time flat.

Thanks to everyone for the quick replies. I went with the Naptha and plastic scraper method which was quite successful.

Total time: <3 hours
Total cost: <$5
Total satisfaction: very high

This job was much easier than I expected, and I encourage others to take the time to check it off their "to do" list.

Based on the comments saying that later models did not have the insulation from the factory, I don't plan to replace the liner.

That's funny <img src="graemlins/roflmao.gif" border="0" alt="[hiha]" /> .

If you're working from the side of the car I have found your shirt works well too. Disdvantage with your method is YOU have to wash your hair whereas the advantage to mine is the WIFE washes the shirt.

 

Try using denatured alcohol.

 

Sorry, double post.

Hmm, my 88na came with hood liners. Interestingly, the LEFT (intake) side crumbled away, and the RIGHT (exhaust) side is intact. Maybe the PO replaced the RH one.

I got 98% of the crud off with carb cleaner. The other 2% can stay there.

Functionally, the hood pads might protect the paint and slightly reduce noise. If I did replace them, I would go for the foil-faced type, for the sole reason that it would reflect shop lights usefully down into the engine bay.
