Radiator Cap Plastic Vs Metal

[idoari 10]

Hi,

 

I need to replace my radiator cap but i saw that peugeot replace the original metal one for plastic one.

i have the plastic one but it doesn't sit right on the expension tank the problem is that the metal one is only avaliable after market not (first-line).

 

What are the difference between the plastic and the metal one? do i better but the metal first line over the genuine plastic one?

 

the plastic one (part number 1306.85)

 

 

thanks

the only difference is the material.

there are other plastic caps which are not directly compatible from other vehicles, however if supplied under the o.e part number for a 205, they are the same specification

Plastic one's have never fitted correctly, even when I had the odd one from Peugeot. so its metal every time, loads listed on Ebay

As above, I have a plastic one on mine ATM and its a bag of s*ite.
