heat shield on punto

hi,i have a fiat punto 1.2..2001 reg,my heat shield on it,became loose,and a guy whos mum i know took it off n sed he'd get me another one,from a scrapyard,he told me to not drive far either or my car would set afire,,this was in april 2011,n i haven't seen him since ,is it dangerous to drive without it?i had my punto in for it's M.O.T today n the advisory sheet says front exhaust heat shield insecure,but it looked to me like the guy who stole my heat shield stole a big piece of it!! im scared to drive far! is it safe?am actually happy cos my car only failed the MOT on a wiper,a bulb n a tyre but this heat shield thing is worrying me.

Scaremongering stuff!
It should be ok but better with the shield. You could get one from a breakers but it might have to be fixed with twisted wire as the bolts are probably rusted up.

Re: heat shield on punto

If it's the front one (runs down the manifold in front of the engine) it'll be OK -- Cento turbos generally run without them and the manifolds get way beyond cherry red (which is bleddy hot).

I'd ask the MOT folk how to secure/remove it. Assuming that it's not a manicat (where the catalytic converter forms part of the manifold) you could use thermal exhaust bandage/lagging, but I'd be inclined not to bother.

it has to be a manicat if its a y reg 1.2
these covers make the engine bay look pretty but reasonably on a cooking car do nowt as you say,the radiator wont melt or anthing
leave it be or remove it completely OP
be aware they are made of razor blades mind

Re: heat shield on punto

Not had one in years - mine rattles and rattled, the local exhaust place took it off for me when fixing the exhaust rattles

Never had a problem

just make sure nothing is near it that shouldnt be like wires and stuff

Amen. I always thought the real reason for the heat shield was to keep the cat as hot as possible by shielding it from the air.

Re: heat shield on punto

Heh, I took mine off. I was meaning to put it back on again but the bottom bits that it bolts onto came off with it, and the bolts and washers holding it on the top had turned into rust, and the aluminium around the washers had corroded away, so there's simply no way to put it back on again sensibly that I can see!

It's been to two garages since, once a fiat main dealer for a service, and neither commented on its absence. From this, I can only assume that it's just not necessary.

Re: heat shield on punto

Distance shouldn't make any difference.

Re: heat shield on punto

Have seen lots of cars without them with no apparent ill effects. Remember puntos in some countries are running in ambients of over 40 degrees and you don't want the exhaust heating the radiator. Having one fitted is better in theory , less chance of burning youself or wires , lower exhaust back pressure, cat hotter sooner , etc etc - but would you ever see a difference? I don't think so. In theory an ocean liner sinks a bit if you put a feather on the deck.

Re: heat shield on punto

my daily user punto in my possesion at the moment is cover less and i have absolutely no concerns, in fact if i wanted to warm a pie up for lunch then it could be a bonus being cover less it would get warmer quickly and think of the savings over turning on the microwave,just got to work out how to get the horn to sound at 2 minutes 30 seconds now

Re: heat shield on punto

if its the shield under the car then worry, if its the one in the engine bay don't worry that one is to keep the cat hot not keep heat away from other bits
