The OEM rad cap is rated at 1.37 bar (137Kpa) so using a 1.3 bar cap on the expansion tank is fine. The rad cap should have the higher lift pressure and be one way only. (no suction return usually denoted by not having any "wings")

 

Higher value cap on the rad otherwise the steam/bubbles etc can't escape from the highest point in the system and build up in the header tank.

 

Such confusion. I originally had it on the rad but was told it needs to go on the top as per the instructions in the box. ( I didnt read them)
So I've put it there. I am tempted to bin it and buy oem just to ensure the correct pressures are there.

i have the same rad and rad cap but have mine on the rad , it came with the radiator so just kept it on there, it could be wrong then

 

1.1 bar on expansion tank and as Don says 1.3 with no wings on the rad keeps everything right. Long story but we proved it was the case with two 1.3 bar caps the rad ended up with air in the system and an empty expansion tank and overflow bottle.

 

OEM cooling system caps

 

new grill to fill that big hole at the front

 

Looking great johnny, i prefer full grille to 3/4 one, good choice.....

i know when i fitted mine, it was a bit of a squeaky bum time drilling the holes

 

Changed the cap to save confusion.

My boost and water temp sensor gauge have died. No lights nothing. Unplugged and replugged in but not sure whats going on.

 

Yeah i know what you mean

 

Needed my lights restoring for a while and £35 was worth every penny

 

that numberplate holder is 👌👌👌

 

Thats acracking job Robsey, what kit did you use? im looking to do mine, Thanks

 

I paid someone

 

aww ok, cheers

 

replaced the under bonnet insulation as the original stuff was crumbling to pieces

 

superb 🥰
what did you use if you don’t mind me asking pal and links for the bits and any more pics on how you did it please Defo one on the to do list looks brilliant and tidy 👌👌👌

 

Lord Harding on here had or has a custom made one on his wagon but i asked him where he got it b4 and i think the person or company who did it no longer make um, a lot of ppl take the blanket off and leave it off with no harm done, not really sure if it's there for sound deadening purposes or as fire protection or a bit of both

 

I just used that foil-backed insulation that you get from Wickes, B&Q etc. I think people use it in their houses for insulating bay windows and ceilings. It’s foil on one side and fibrous material in the other and is about 1cm thick.

To put it on I removed all of the original clips, which I always seem to break lol no matter how gentle I am and I used the old insulation as a template for the new stuff. The new clips I got from the local Motor factors at like 10p each or something. To get the new clips in I had to tap them with a hammer as they are quite stubborn to go in.

 

the foil one looks really nice 👌

But that’s true never thought of it like that is it for sound proofing or fire protection but 8 assume it will Defo be fire resistant what’s on there now the genuine one that you can use as a template

I wonder if you can use dynamat like stuff

 

It's a fire suppressant if there's an engine bay fire the plastic tabs are supposed to melt and the blanket is supposed to fall down and suppress the fire.

 

Thats what ive heard too, it gives you enough time to get out of the car before the fire gets out of hand .

 

Good job

 

This is a friends car, he has something similar but its custom made-

 

nice Reg plate 👌

 

so once you’ve made the template and cut it out ready to put on
original one can get put to one side or thrown away no need to put it underneath the one you’ve made?

sorry for all the questions pal looking forward to doing this mod on the weekend it really sets the engine bay off the wr1 is superb aswell 🤞

 

I chucked the old one out after I’d finished using it for a template as it was floppy and falling to bits. I suppose you could try putting the old one on as well as a new one but I think that would make the overall thickness too much and the clips might not be able to hold them both in place

 

gonna chuck mine aswell then as it’s watermarked we’re ive gone happy with the jetwash Defo doing this mod for sure it’s in the list 👌👍

 

Just make sure whatever you guys are using is fire resistant. The engine bay gets hot and you don't want it catching fire.

 

I’ve seen this one what you reckon?

I honestly don't know mate. I looked at the advert and even though it says aluminium it doesn't say what else is in it. The insulation part could be anything and building regs will be very different to car regs. Like I said I don't want your car catching fire or anyone elses for that matter especially if you have family or passengers.

The classics don't have anything in the bonnet lol, weight reduction and more engine noise.

Have a look at fire proof material or heat resistant insulation that can handle engine bay temps that way it will keep engine heat in the engine bay so your bonnet will be easier to touch.
