Importance of heat shields?

And after a few years more the heatshields corrode and fall out of the penny washers, then it is time to resort to a bit of drilled flat bar held by the bolts on either side.

During a DPF regen for example, the temp can easily reach 600C+, if its blocked then they can go even higher, therefore heatshields are an essential safety aspect, even none DPF cars can have faults which raise the exhaust temps.

Unfortunately standards vary between MoT testers but its not our test, it belongs to the DVSA and we just follow the rules and regulations as laid down by their training and manuals (or at least i do!)

100% Uncle Phil.
Although only 2 have failed by me,
1 was a car purchased by a foreign couple who bought a car from a trader with no MOT on it.
2 was a rather upset guy who knew his car had a problem with the shields, but chose to ignore it.

Where possible, I do a PRS assuming I have the appropriate materials to re-fit a loose one.

As we have discussed in the past, there are the pub goers crew who know everything about cars after a few jars, but often proved wrong.

Strangely enough, I obtained a replacement fuel tank heatshield for the ZT last week.

It's not had one fitted in all of the time I've owned it, and I couldn't pass up the opportunity to grab one from a car that was making it's final journey, when I was removing the FBH dosing pump.

I have to say I'll be fitting it at the weekend, when I drop the exhaust off to allow the subframe to be removed, I hope it's snowing though, I wouldn't feel happy doing the job in a nice dry workshop on a 2 post lift, when I can relax on my driveway

Onward and upward

Don't be mislead Brian. The MOT ramp with air operated beam jack is much over-stated, the air conditioning is freaky cold where I work with no heat, apart from the Tester's office.
The ramp has been a real handy tool for me when the MOT diary is a bit slack, my oddball 75 has received many treats to include underside protection, brake adjustments among a host of other benefits.
I do miss doing clutches on the floor though, got any lined up to do ?

Sounds like I have the latest in grease-monkey comfort, a piece of oil-stained carpet to provide some protection from the cold, damp stone slabs of my barn floor. I'll probably be spending some time there over Christmas, the in-laws and out-laws are arriving en-masse in a few days!

Yep, it's a clutch and flywheel this weekend John, you can't beat avoiding last minute Christmas shopping, or indeed any Christmas shopping by fitting a clutch on your driveway.

I'm really looking forward to doing it on axle stands, rather than using my two post lift, which is a bit of a sore point at the moment

Apologies, I bought the remaining stock of these from China.

But then we also have varying standards by mot testers as stated in a previous post so it's not all the " pub goers fault"

I posted what I was told by a garage which I started to use after my local guy had retired , I don't know them apart from mots and tyres , which I's all I use them for.

If one year the rule is not in the mot testers bible and then it is put in the following year , how does that make the car any more dangerous than it was the previous year?

Can anyone shed some light on if this ruling is valid in other countries , France, Ireland, n Ireland etc?

That is not correct. You do not get an advisory for a fitted under tray. The advisory is for the fact that the tester cannot see and therefore advise on teh state of the car behind the under tray.
