Replacing your radiator hoses is one way to minimize the chance of engine failure and breakdowns. A visual inspection of your hoses can help you determine the proper time to replace them. Cracks, bulges, and hardened hoses are all signs that your radiator hoses are nearing the end of their useful life. But other unseen problems can occur from the inside which is called a electro-chemical attack on the rubber compound in the hose from sitting for long periods. This is most common failure now days in Classic cars. Another sign is poor heating system performance, this indicates a problem with your hoses. Heat, vibrations, and corrosion are all contributing factors to bad radiator hoses. A coolant leak in either green, red, or yellow liquid is another warning sign of a cracked or corroded radiator hose that should be replaced. Bad hoses can cause serious engine damage through an overheating engine or catastrophic failure. Order a new set of hoses before your old hoses leave you in some neighborhood where you don't want to be.

Radiator Connector Pipe
The lower radiator hose is actually made up of two separate short hoses with a metal connector pipe. With the design of the Triumph TR2 to TR4A it has a fairly tall engine and also a tall, narrow radiator. Consequently, the distance from the lower radiator outlet to the water pump hose fitting is about a foot and a half. This would be an excessive distance to be spanned by a single rubber hose. Triumph engineered a solution by using short rubber hoses and a steel connector pipe which worked very well until the steel connector pipe rusts out. To answer this somewhat vexing problem, we now stock a stainless steel replacement pipe. It is an excellent copy of the original, but in non-rusting stainless and you’ll be a lot happier looking down at this shiny stainless pipe than a rusted mess
