1970 Lower Radiator hose frustration
« on: August 12, 2018, 04:22:35 pm »
Is there anyone who manufactures / sells the lower radiator hose with the right bend that fits a 302 Boss 70? Have tried with two "concours" from NPD but failed to get them free from the power steering belt . Seems to be a common problem with the aftermarket lower hoses !

Try using a 1970 351W lower hose. They are a bit longer and have a more pronounced 'bend' away from the power accessories.

Current lifelong project:
1969 Mustang Fastback/FOX chassis, 6 speed, 4 wheel discs, with a modern Can-Am 494 (Boss 429), Kaase headed, intake mounted with a 1425 cfm 'B' Autolite Inline carb, ala Trans-Am style…Whew!
Another 'project' in the works!! For now, its top secret...

The lower hose is always a tight fit in that area. However, if you buy one of the Marti hoses you will find it takes very little fiddling to get the hose to clear the belt ;-)

I replaced by original lower hose with a ford approved replacement.  Perfect fit.  I think it may have been scott drake.  I don't think it was from kevin marti.

I have the same problem. Not with my Boss as it doesn't have P/S but my 70 351C Mach 1 does. The repo replacement lower rad hose gave me the same problem. The P/S hose rubbed against the hose and it began leaking. I had to reinstall the original factory hose which is still in good shape but its 48 years old. The repo hoses don't have the slight clearance jog near the water pump outlet. I went to Auto Zone and got a 351W replacement hose and it does have the jog at the water pump end. Haven't tried it yet but it appears it will work.

I would also try Marti, maybe a slight trimming on the hose and final question do you have the correct radiator installed?

I have the Marti hose and it fits pretty good. No trimming was needed, but did have to rotate it slightly to find where it cleared the PS belt the most. There is about .75" clearance between the hose and belt.

The 351W Lower hose did work,I had to trim a little over and inch but it went in and now clears the lower belt,by two inches.

Thanks for the tip

Make sure you have a spring in the lower hose,because of the sharper bend.

Yes, a spring may solve my problem. I managed to get the hose free from the belt, but then I got a sharp bend on it.

I'll try a spring.

Thanks for that tip !
