Cooling Parts for 105 Series Alfa Romeo

We now offer this complete package containing all the hoses you’ll need for early 105 cars.

The pros of using silicone hoses include a greater operating temperature range, more flexibility, increased resilience and a longer lifespan.

It is designed to fit cars with twin carburettor inlet manifolds with the large screw-in thermostat (not single carburettor 1600 / 1300Ti) and for cars with early radiators fitted with 4 legs and early heater boxes (i.e. Sprint GTV, early GT Junior, Duetto, early Giulia Super, 1300 / 1600 GTA etc).

Due to cars having had engine transplants over the years, please check the compatibility of components before ordering). If your car has had an engine transplant, please let us know the details and we can customise this kit to be compatible.
