Default Need New RAD Hoses

I have a 1996 sportsman 500 with a little over 600 miles. I am the 3rd owner. So it has done a lot of sitting. Went for a ride yesterday and blew a hose but was able to get back to the garage without overheating. Checked a couple of sites cheap parts and amazon and don't show a replacement. Anyone use other type of hose that will work? Thought about heater hose looks to be same size maybe a silicon type if heat resistant. Any info appreciated.

1 inch inside diameter hoses. You can use standard automotive heater hose in that size in most cases.Don't have to use a silicone hose. Some of the oem hoses that are preformed can be a little problem on replacement,but just make sure there are no kinks and you shouldn't have any problems. Be sure to bleed all the air from the system.Fill the radiator up,leave the cap off and let the fan cycle on and off several times.

Thanks OPT, I thought I had read that on some of the previous boards. I have an additional question, My fan does not come on very often, I know not the usual problem, it does come on but not very often. I am not a fast or mudder just a slow trail rider, I was wondering if a lower range contact would be in order or leave well enough alone? Thanks in advance.

First thing is to make sure the radiator is clean font to rear.It may look clean but dirt can pack up at the rear. Second thing is to replace the temp sensor on the radiator. Simple two pronged sensor that's nla through Polaris but you can match them up at most auto stores.Last could be the old motor may be getting weak. Replacement motors are high $ but on ebay they show Spal type fans that can replace these old style motors with the metal blades if needed.

Try to stay with the same rating if you can.Wouldn't hurt though if a replacement is a tad lower temp to trigger the fan. If the fan doesn't trigger any faster then you may need to look for a fan replacement.

Hose may have a pin hole that you didn't spot.If you have new hoses just replaced them.Or you can reinstall the original,find the leak,cut the bad section out and use a pipe for a splice and a couple clamps. If it's not the hoses,could be a small leak in the radiator vanes causing the steam or the over flow line at the cap area leading to the reservoir bottle may have a leak.

Got the new hoses on. I could not route them back to the original was due to stiffness. I had to run one over top the exhaust to the front. Any ideas to put over this one hose close to the exhaust? I was thinking maybe metal tape or I have some exhaust wrap left maybe put that over the rubber hose or do you think it would keep the heat in? The fan never came on or the hot light once I filled the rad up. I will check the temp trigger and most likely get a new one. Ran it hard for 20 minutes or so no leaks, no hot light and no fan.

Use the heat wrap on that one hose. If you have heat problems with this hose,you can always install the oem preformed hose you have,repair it like I showed earlier if you find a leak on it.Oem hoses are expensive,some you can't get anymore,but can be repaired if need be. Hopefully the sensor solves the fan problem,plus you can always run 12 volts to the fan to make sure it's operating properly also.
