Engine and Auxiliaries including Cooling

New: Engine oil special deal, see Section 5.

All gaskets and hoses are available newly made. Pistons, rings, bearings and valves are also now available in certain sizes.

Silicone radiator hoses are now available from The Imp Club at £120 for the set of three.

Note: We usually have a range of re-conditioned radiators in stock and also re-con water pumps. Rads and pumps are available on an exchange basis – there is a surcharge, re-fundable on return of the old part, and may be additional postal cost. Unfortunately the quality of some of the old ones returned means that there has been a price increase. Please try to return good ones!

Note: Re-conditioned items carry a replacement warranty for six months from time of sale. If you are not happy with what you have received, please contact us immediately and a re-fund or replacement can be arranged.
