Rubber hose repair

Post by **d_harris** » Wed Jul 01, 2009 8:32 pm

Hi all,

I've got a small split in one of the hoses on the modern (fortunatly its in an easily accessible place)

Anyone know of any remedies until I can get down to the factors to get a replacement?

Cheers

Try winding pvc insulating tape round and fitting a jubilee clip

Use the minor?

if you've got some self amalgamating tape, then use it...

Hope it's not a brake hose.

if its a water pipe can you find a pipe that will fit in side it then cut it where its split poke a pipe in an put 2 juberlee clips on it
if its a vacume pipe for s servo them new washing machine pipes that are
thiner than the old ones are suposed to be the right size

its a rad hose - sadly taking the trav to the national pretty much used up the last of its mileage allowance and Claire wont ride in it (stupid girl)

Try winding pvc insulating tape

and leave the rad cap loose. it will run a bit hotter but it will not pressurise the system.

Why will it run hotter ?

Post by **8009STEVE** » Thu Jul 02, 2009 5:32 pm

Because water under pressure has a higher boiling point

Sorry, Just woke up. above is true fact., but wrong answer.
Correct answer, It just does.

it'll also chuck it all out!

I've checked the local factors and they dont stock the right hose

I'm going to the scrappy on saturday to see if I can get a decent s/h one.

The correct answer is - NO , it doesn't!!

I used to have from a plumbers a pipe repair tape set which was basically a roll of rubber self-amalgamating tape and a roll of black clloth tape of the type that used to be used as insulating tape. The self-amalgamating is waterproof but weak while the cloth stuff bound tightly over the rubber stuff gives the strength.

Thanks for that DP - a very useful and neat solution!

I bow to the knowledge of the almighty rular. Only having 37 years experience as a mechanic, a lot of that time on Roadside repair/recovery, I now realise that I have been doing it wrong for all that time. I feel a career change coming on. What would the almighty rular suggest?

There is no logic to the idea that a pressure cap makes the engine run cooler. Yes - the water will boil at a higher temperature - so all the cap does is it delays the point where water evolves into steam - but the temperature rises just the same. The cap has no effect on that - it simply contains the water, and raises the eventual boiling point. Once water boils - it no longer circulates properly and can no longer cool the engine - the evolution into steam causes massive increase in pressure if the volume remains constant (Charles's Law) - it's how my steam loco works ! - and the cap then releases that pressure - with subsequent loss of coolant. Which is bad news all round really. So - effectively - the pressure cap simply helps the engine coolant to survive as a liquid over short periods of stress (hill climbing etc) and prevents coolant loss until it finally is forced to let go - to prevent the system from bursting eleswhere. The temperature of the coolant rises just the same - whether pressure cap in place or not - but with NO cap - it boils into steam at 100 C, if cap fitted the boiling is delayed until 110 maybe even 120 C !

You stick with steam engines. I will stick with the internal combustion engine. I know what I am doing, you know what you are doing.
It goes against all the laws of physics, but the car will run hotter (accordinging to the temp gauge).

Aah - against the Laws of Physics - hmmm..

Well, I know that without the rad cap the underside of the bonnet gets redecorated

, so not really an avenue i'd want to explore!
