Aygo Radiator Coolant Cap

[Oscarmax]

The plastic coolant filler cap is broken, does anyone know were I can get a replacement, I do not want to buy a complete radiator ?

I assume you're referring to the cap for the expansion tank? You should be able to go to a Toyota dealership and get one for something like £10/£20. Alternatively you can look for a Peugeot 107/Citroen C1/Toyota Aygo being broken on eBay and buy one that way.

When I lost a cap on a Honda CR-V I had, I had to wait a week to get a replacement but had to use the car. As silly/gross as it sounds, I got a condom and a rubber band and used that to cover the hole. It's not pressured (I don't think), but was handy for stopping debris getting in to the coolant bottle.

I am referring to the black plastic cap to the top of the radiator, not the pressure cap, as a temporary measure I have stock it down with some Silaflex adhesive sealant, use for sticking solar panels to caravan roofs.
