Cooling Problems
Need a little help with this one:
rather then using a hose between the water pump and the radiator I had a piece of tube bent to shape. When the motor gets warm...water temp around 90c the tube comes out of the hose that connects it to the water pump. My radiator cap is 14 to 18 lb...hose clamps are tight! Jon |
Jon,
Maybe a couple of things that would help. If you have enough length to the tube see if you can get a ridge around the end of it to slip the hose over and then put the clamp behind the ridge. Also a friend who had a similar problem just roughed up then end of the tube so it wasn't slick and so far as I know he never had any more problems. I believe he ran a 14 pound cap. Ron |
If you cannot find a shop in your area capable of putting a rib (ring) around each end of the tube about 1/4" from the ends, you can have a welder put 3 or 4 "dots" of weld material around the perimeter. OR form a circular ring the diameter of the outer tube from 1/16" welding rod and solder it in place, thereby creating a ring. any of these will work.

the bend not be bent and line up correctly----in other words--if the angle of the water pump outlet and the radiator inlet are not in the same plane, you will never get it to stay on unless you put a second bend in the tube to match the second angle

Rick Parkers suggestions are right on.
Also, it is critical to double clamp all hose connections. The engines in most of these cars move around much more than production automobiles. If you are using gear type clamps, be sure to purchase "ALL" stainless clamps. That means the screw is also stainless, not just the band. That enables you to tighten them tighter than the standard clamps with cad plated screws. 40 yrs of swimming pool experience speaking.:LOL::LOL: Craig |
I agreethat a bead , ridge, etc on the end of the tube helps----but in this case--if he only had one bend put in the tube----the ends don't line up with the rad and water pump. the centerlines are not in the same plane and the hard tube will never stay attached without putting the connecting hoses in a stress ----

JC:
I agree with what you feel is a problem, however, by using a short piece of curved hose where the tube attaches at the top of the radiator the concern is eliminated. Many different angles are available to help alliviate this problem. Make the majority of the run out of a "L" shaped tube, it will look better and the short pieces of connecting hose will reduce the chance of an actual hose failure. |
I had a muffler shop put a slight flare on the ends of my pipe then I affixed my clamps behind the flare.
|
i use double clamps on all my aluminum pipe with no ridge. have not had any problems, yet. run a 20# cap.
|
On pieces of tubing that will fit into my lathe( 36 cc) I will put a knurled pattern before bending the tube---works good for hoses, pedals, and other handles
