Radiator Hose Spring

[bytor]

One of the to-do's I have lined up for the winter is to replace all my coolant hoses on my 87 vette. I'm almost certain all the current hoses are factory original.
My question is, it seems most of the Gates replacement hoses don't have the 'spring' in them. I'm wondering is there a brand that has the spring installed? I went through this on my 78 and ended up removing the spring out of the old hose and installing it in the new hose. Not ideal.

If you can't find a hose w a spring, then could you make one?

How complicated is the curvature of the hose?

If your having cooling issues, you may also want to hold the engine rpms at about 3000 rpm for awhile and carefully inspect the LOWER radiator hose, if its old it may be collapsing partially under the water pumps suction reducing coolant flow, this may not be obvious because at times it takes 1-2 minutes to happen and it only happens one the engine coolant reaches about 170F plus which tends too soften the radiator hose rubber.
Id also point out that a sticky t-stat or a partly clogged radiator can contribute to over heating in a normal fully adequate cooling system, and that OIL FLOW is what does much of the initial engine cooling, so a large baffled oil pan with a added oil cooler can remove a great deal of engine heat before it can reach the radiator.

these springs, inserted into the lower radiator hose prevent suction from the water pump closing the hose, preventing or restricting coolant flow
most of you know there are different types of hose clamps, but most of you may not understand the differences in strength,quality,dependability and what should be used.

most guys use the worm gear clamps as they function, they are dirt cheap compared to most quality clamps and they rarely fail, if not over tightened if they are not rusted, but they can be hard to start and can cross thread and break rather easily, its bet to think of them as one time use.

THERES THE FAR STRONGER AND MORE DURABLE T-BOLT CLAMP

the even better spring loaded t-bolt clamp that self adjusts slightly to maintain a firm clamp force, this type is the best choice if routing flex hose to supply pressurized air ducted from a turbo to a plenum, where loads, stress and pressure, shift constantly

the wire band clamps that have the nasty habit of cutting into hoses and causing leaks

[b]spring/ring clamps that are fast for a manufacturer with the correct tool to install but usually a true P.I.T.A. for the home mechanic to deal with[/b]
