New Yeti Owner with a dumb Q

My near new Yeti does not have one of the above under the bonnet. I noticed this because I could barely touch the bonnet to flip it up the other night.

As a consequence after a 15 min drive you can fry an egg on the bonnet of our car. The above site supplies these items for quote ... " for cars which came from the factory without this panel" .... somebody please tell me that I do not have to buy one of these to stop cooking my bonnet every time I go for a drive

It shouldn't be getting that hot.

Is there any part hotter than the other, and if so, what is under that part of the bonnet?

[SGG]

Its hot .. too hot .. and its because the cover that should be there isnt there.

Shouldn't be getting so hot that you cant touch it - our Golf doesn't have this piece either (was falling to bits so i removed it) and the bonnet doesn't get that hot.

I plan to replace the sound deadening soon but im not worried about leaving it bare for a few months - many cheaper cars do not have any deadening here.

Well i can touch it but in 30+ years of driving Ive never felt a bonnet thats so hot for so long. I cant believe that heat and sound management could be sacrificed for a few bucks

It cant be good for the paint work to directly exposed to to the heat generated by this engine?

I meant what part of the engine is under the bit that is the hottest.

You can always put some suitable insulation, I'd check Bunnings.

If something is just 50degC hot it will burn your hands when you touch it just for few seconds, so the hand is accurate enough for sensing the temperatures around 50deg.C no more. The bonnet and the roof of your car on a hot day would be much hotter. The paint on the cars is usually baked in oven at +80deg.C. So, I'm sure tat the paint on the bonnet of Yeti will be okay.

The bonnet in that Yeti is close to the turbo, so it gets bit hotter, I would definitely insulate.

You don't say what engine you have but generally the diesels have the insulator & the petrol does not.

As for your past cars, maybe you didn't realise how hot they were getting? I can think of a few of my previous rides that were getting up around 80c and the VB V8 commodore cooked the paint to crows feet. IIRC, touch test is that 70c becomes uncomfortable after 5 seconds but we were experimenting with that on a 75c electric motor last week and there was a huge variance in the resiliance of peoples hands.

My TSI octavia came without the insulator & I convinced the dealer it was missing & they fitted one as a warranty item. That was in 2008 when the dealers didn't have a clue.

You can buy them on Aliexpress for ~$80 posted

Or organise a group buy for 10 units & get them for $40 each

They are probably ~$120 from the dealership & if you whinge to sales enough you might get it for trade price & save $20.

Clark rubber used to do a self adhesive, foil backed, heat reflecting foam that would work but it's expensive.

These places will have better stuff than Bunnings

Personally, I'd just go the OEM route. You'll have forgotten the cost in a month or two.

I know that surface temperature on touch could be a bit different scenario, not much though, but I can assure you that 55degC hot water would within 5 second make your hand more than uncomfortable.

...unless you wear the gloves.

We were trying to determine how hot an electric motor was getting on a dragging actuator the other day. 3x engineers, a fitter & an operator all doing the touch test with varying results (I must have asbestos hands) until the fitter remembered he had an infrared thermometer in the truck.... temp was hovering around 73-77.

If nothing else, it proved that trying to ascertain temperature by touch is extremely innacurate & variable.

I'm sure the insulation is there for sound not heat.
As was mentioned, the diesel has it but runs cooler than the petrol versions. When the vehicle stops the heat will soak into the bonnet, always has. That's why cats get on there in the winter.

The insulation is fitted to the diesels to reduce noise but also help them heat up quicker.

I have the 90tsi but yeah I guess you are right .... I need to get out more often

Thanks for the 2c worth/links. I reckon I will probably let the dealer loose on my wallet yet again .... they want $120 plus $60 for the 12 locking nuts.

As to the fried egg link I just might call A Current Affair and get them to film me knocking up an omelet on the bonnet in the dealers car park

12 locking nuts? Do you mean the clips that hold it in?

They come with the insulator like the genuine part $80 unit at aliexpress. $60 is bending you over and taking you for a fool.

The clips are partno 1H5863849A
Sound deadener with clips is 5L0863831

Thx for the heads up .... I will check the insulator package on Friday when I collect it
