Overheating - it may be a tired radiator cap
Whilst this small tip may be one of the shortest notes in the V8 Workshop Notes series it is sound advice nonetheless. Radiator caps are often seen as a long life item and indeed many give service for many years, but eventually they grow tired and no longer perform well holding the pressure in the cooling system. Then they can contribute to overheating.

So routine periodic replacement is wise at periods of say ten years. A replacement cap GRC110 costs less than a fiver including VAT.
For more details see the online parts catalogue for the MGBGTV8 cooling system on the Brown & Gammons website.
