Hello all! Im about to replace my radiator hoses with ASR silicone hoses and was wondering if any sort of sealant should be used before I install them. I bought all new clamps to go with the hoses. Thanks.
You can use a screw clamp from Napa. If you tighten it too tight, it will cut the hose. You can use a liner or buy a liner clamp if you don't want the clamp thread holes to cut the surface of the hose. Another solution is to wrap some self fusing rubber tape around the hose so the edges can be covered as well (plumbing and sometimes electrical department Home improvement Center). The flats on the clamp will prevent the edges from cutting further into the hose. So, the tape gets cut but the hose doesn't. The problem with the screw clamps is that they do not self tighten like a OEM clamp as the hose compacts over time so you will have to snug them periodically until the hose bottoms out. A screw clamps that looks perfect when installed may be too tight because the worm drive is very powerful. Too tight application causes the hose to expand out the sides of the clamp and tears the internal structure.There were no actual instructions. Now Im wondering if I should use different clamps rather than the NAPA standard worm gear clamps. Thanks!!
