Lower Rad Hose

[rob love]

With any luck I will be installing a set on the 2VP carrier at work in a couple weeks. As it is a bare hull right now, it will let me see the angles and the stresses.

I used a fairly heavy bulk hose on my carrier. I ended up sending my rad for cleaning and pressure testing due to overheating along with a slight leak. On re-installation, I noticed the slight leak around the inlet, and realized the lower hose was causing stress, especially on one side of the rad.

A year back I bought 3 hulls, and on one of them, it turned out there was a good engine. I bought the hulls expecting the one engine to be a boat anchor. On draining the antifreeze, I noticed the little correction bend in the lower hoses and realised that I had made an error on mine. As well, a look in FUC-3 shows the little wave in the lower hose. I always thought they were just bulk hose when in fact they are preformed.

You can get RADIATOR HOSE with an external helix, making it possible to bend without kinking. Any industrial HOSE stockists or dealer worth their salt can get it. If anyone needs help, I can find out its correct name (well here in UK anyway) but most is produced abroad!

In the trade we call that flex hose. Dayco manufactures it....here is a chart of the available sizes and lengths: http://www.daycoproducts.com/stuff/c...diatorhose.gif

The part number from Dayco is 81281. Slightly longer but it should do the trick. These were installed on the 2VP carrier I took apart at work. There will still be some stress on the inlet due to the short span, but it will be better than straight hose.

The NAPA equivalent for the flex hose is FM09 and is roughly half the price of the pre-formed ones.

Personally, I'm going for the preformed.

So lots of carriers out there moving about. What have others used?

The stuff we use comes in 1M lengths and has helix the full length to be cut to size

I can't say that I have ever seen bulk flex radiator hose. What stops it from leaking at the hose clamps?

[Paul Dutton]

With the helix being on the outside the inside is smooth!! So clamping isn't a problem. Haven't any on my van outside or would take a pic for you. We use a lot of 2" stuff on excavators and plant. If it works on them it will do a carrier!

Rob, have you seen the photo in the early carrier thread?
