I got my heat shield in the mail a few days ago (the one in the pic), and I'd like to install it as soon as the weather improves (May 2008?). I just emptied half a can on WD40 on all the nuts I could see under the bonnet, and will probably give it a few more sprays before I try loosening any nuts. Anyhow, are there any tips to installing it? Do I need to remove the radiator (this heat shield looks positively huge compared to the current one)? Do I need to jack it up to access the bottom nut (the current one only uses the top two points, and I couldn't locate the third one)?
