Technical what bottom hose

sbc into 51 chevy truck what bottom hose on the radiator.

 

Bend a wire on the water pump to radiator make it an L shape. Go to your local auto parts store and look on the rack for one that will work.

 

Or measure the diameters of the places it has to fit, then measure the length along a nice gentle bend, and get a universal flex hose.

(it's guesswork to know what radiator you have and where you located the engine and how long the water pump is and what else is in the way of the hose, etc)

 

like squirrel said. Go to NAPA find an oletimer ta hep ya. They make em with different id's on the same hose so rad OD and engine OD can be different. You can also use a piece of hose to make the OD larger and get a hose that fits over that hose in case you have trouble matching , luck

 

thanks for the replies.no napa stores here.cant access the NAPA site access denied whatever that's about.ive been informed an o reilly 20242 hose may do.engine was donated by a 71 vette.3 trucks ive worked on have v8 conversions.a 51,52 and a 38.radiators are all similar size.19 in wibe and radiator centred in the stock bracketry.all have aftermarket aluminium radiators with the outlet near as can be in the bottom right hand corner as I sit in the trucks.the 51 and the 52 have a moulded hose mine the 38 has a green stripe gates gs26501 1 3/4 x 13 1/2 long.if I could find out what will fit one it should fit all 3.top hoses are not an issue. o reilley 20242 picturedback face of rad is 8in from the centreline of the waterpump outlet.centre of bottom outlet is 6 3/4 from centre of crank pulley.the flexi hose feels quiet stiff will it become more plyable when it gets hot nothing in the way of the hose .thanks for your time nunattax

 

There are different grades of flex hoses, the lighter ones bend more easily (gates "red", as opposed to the heavy duty "green")

Did you check the stock hose for a 56 truck with V8?

Dayco 70155 for example

 

Will one of these fit ?

The WWW is a big place. Take a look around. Many forums to ask, they would know better, like the dealers of this old stuff would...

I've taken one of those aluminum pre-heater hoses that came on 80s cars that run from the exhaust manifold to the air cleaner and I bend it to shape then take it down to the parts house and say I need a hose this shape with x size on this end and x size on the other. So far I've always got what I need.

 

I've had good luck with the lower hose from a 65 mustang V8. It fits the small block Chevy in my 32 and the radiator outlet is on right side (looking at it.. passenger side of car)

 

thanks for the replies.i didn't know the difference between the red and green stripe hoses.if I got a proper reply from the guy who built the 51 id be sorted.i like to be sure im ordering the correct part as everything costs a lot by the time its been shipped here

 

I should be able to check out the mustang hose there are quite a few around thanks

 

Some of my notes on possible radiator hose matches. Not saying they will fit but might give you some possibles. The reference to 49-54 Chevy car sounds like a close match.

- A 64-66 Chevelle, 1966 Ford Fairlane 289 lower hose, lower hose NBH 7286/Gates 20475/Goodyear 60620/Dayco 70368/Parts Master 80074 for a 283, 1.75” ID, 14.5” OAL or a NBH 7341/Gates 20544/Dayco 70470 (tighter bends) for a 396 car with standard cooling seems to fit many broad street rod applications. It fits a small block Chevy to 49-54 Chevy car using the stock downflow radiator pretty well. A little trimming sometimes needed, but it may be as close as you will find in an OEM application.

Or from Horton's, a Cdn Speed Shop:

- , lower # Gates 20510/Goodyear 60366/NAPA NBH 7347 (61-68 Lincoln)

I used straight hoses on my build. I went with something out of the Summit catalog once I knew the length. Look up Dayco and Allstar. I went with a Dayco. Once you know the part number you might find it locally.

 

that's what im trying to do have someone tell me this part fits mine distances are similar from rad to pump..my rad is mounted at a slight angle the bottom is 1/2 forward to give a little more room around the front of the engine.if worse comes to worse I can modify the outlet on the rad but that's a lot of bother compared to just changing a hose

 

jim didn't know there was a 56 chevy truck with v8 that sounds promising is it 1 3/4 on each end
