Lower Rad Hose

[rob love]

When I rebuilt my carrier I ran into a problem with the lower rad hoses. I just used straight hose from the water pump outlet to the rad. I ended up with a leak from one of the radiator inlets, and later realized that the original hoses were not straight, but rather had a slight rise to them.

I recently discovered that the early 50s Ford cars use a similar rad hose to what was on the carrier. Here is a link to the Mac's listing: http://www.macsautoparts.com/ford_me...d-v8-only.html

The hose is also available from NAPA as part number 7013 for about $20Cdn (full retail price is $40....ouch).

I have a set on order now, and know full well how hard it is going to be to hang upside down and change those hoses. Before I do, has anyone else successfully used these later hoses on a carrier?

Maybe this is why my rad always had a slight leak. I've been using marine exhaust hose on my carrier. I chose it as it was pretty cheap and made to handle high temps. A local liquid handling supplier carried it.

Let us know how they fit. I'm sure Macs will suddenly get a small surge in lower rad hose orders if they do.

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
