Title: Engine undertray pics and dimensions
Post by: Bojan on 23 March 2016, 14:51:16: Does anybody have an engine undertray (for a petrol PFL), but not istalled on car?
I would need several photos(form diferent angles), and, afterwards, some messurements.

I am trying to source an OEM one, but no luck so far (quite rare in my part of the world), so I'm planing to fabricate one from steel or aluminum sheet metal. So, if somebody would give me a help with photos/dimensions, I would really appreciate it.

Thanks!

According to how I read the EPC the same undertray fits all cars

I have been strungling with this, TBH.

This plastic cover covers the space from the front cross member (in front) to just in front of the engine sump (in rear), right?
But does the rear low end of the undertray sit lower than the bottom end of the sump?

Diesel undertrays are definitely different to V6 ones.

Helps the engine to warm up quicker too.

Post by: Bojan on 26 March 2016, 17:37:53: Many thanks to danzigfan, as he gave me his old one. :y He even put in an effort of sending it via train (saved time and money). 8)

hAfter Having it installed, and seeing photos that terry paget posted, I'm certain that oil sump was left exposed to aid oil cooling.
I had idea to make a steel plate that will run from the back of plastic undertray to the rear cross member, but I'm having second thoughts now.

All the untertrays on this images are the same, and they fit perfectly to the V6 sump.

Post by: Bojan on 30 March 2016, 06:54:31: Just one more additional note -> I have drove car several times after installing the undertray, and I'm certain that the noise coming from the engine bay. The sound of belt drive, and PAS pump is much lower, almos unnoticable.
