Hi everyone,

I need help finding parts (if it's even possible or replaceable, dealer said Not possible). Decided to change my engine oil today and noticed that the screws weren't screw in all the way and all of them were loose. You can actually move the drip pan up and down.

After removing the pan, the screws and screw holes were worn and rusted. I need to replace the screws and the screw holes. There's a silver cap (I guess) that goes in the screw hole then the screw goes into the silver cap.

The screws should be replaceable but how about the silver cap that's installed on the car (or whatever you call it)? Please provide part number, if they do indeed exist.

Thanks !

My guess is that you are looking at a new subframe.

I'd think somewhere like Fastenalwould have something that would work. Or Mc Masters.

Sorry, when I said drip pan I meant the plastic covering under the engine the prevents rocks or whatever from damaging the bottom.

BTW, thanks for the diagram and clips idea, I'll look into that

Since we only ride the paved streets and have no snow, those plastic pieces have been long discarded.

I was wondering if that piece is even necessary? I thought most cars don't have that cover?

I think the underside shields serve three purposes, improve radiator performance, clean up the airflow under the car, and keep the engine clean. In that order.

I think the underside shields ........ improve radiator performance.......
So partially sealing off the engine box improves the air flow thru the radiator? Hmmm. Maybe, but kinda doubt that. I would want some measurements to see what is true.

i either read an article or heard an expert at a porsche technical session discuss the belly pan on either the cayman or 944 turbo (951). somehow it keeps the air flowing straight back, eliminating turbulance which ncreases radiator cooling, and also increases downforce which may come in handy when turning on a wet highway.

Yup - the belly pan causes suction at the firewall when you drive and pulls all the hot air out. My wife's MINI cooper has an oil cooler at the rear of the engine, just at the rear edge of the belly pan. The engineers would have put it up front had air flow at the rear of the engine been insufficient.

Think of it as part of the radiator fan shroud. Pull one of those off and cooling fails.

Fellas ... these belly shrouds come on nearly everything these days! The Escort, Focus, Mazda MPV, Tributes, Jeep GC, Windstars, etc, etc ...just about everything I recall ...probably every family minivan now comes with them .....did all these high performance vehicle designers envision greater downforces and better wet handling?? Buy into all the marketing bs you want too. If they were so important would they (or at least some of them) be made of cellulose and resin?

Noise damping and road slush deflection .... and, yes, a bit of MPH/MPG improvement.

Is it cheaper to put on a belly pan or install a higher capacity cooling system? Downforce doesn't figure unless you're in the exotic realm.

i dont know why they are not made differently. i do know of problems solved when the belly pan was put back on.

as for downfoce and exotics being mutully exclusive - is that why cars like the chrysler crossfire as a modern example, have a rear spoiler that pops up at a relatively low speed? downforce isnt something you think about until you dont have it.

this is a volvo - safety first nutswinger's forum. why buy a volvo only because it is so safe (it sure isnt for the strikng good looks or sporty handling) and defeat a safety item?
