Radiator hose
« on: April 14, 2010, 12:22:50 AM »
I have a 1987 Suzuki samurai jx I have been noticing that that upper and lower radiator hoses have been sucked flat after my Sammy is warm. I have replaced the radiator cap and thermostat. My question is, are the stock radiator hoses a hard plastic or a hard rubber. I was looking on petroworks.com and they had a hard plastic radiator hose. (mine are rubber) I will probably end up replacing both the upper and lower hose anyway. Do yall know a trusted place on the net to buy them?

The hoses are probably just old and getting soft.  Stock radiator hoses are reinforced rubber hoses...that is what I would replace them with.

I'd just buy them from a local shop.  they're just traditional reinforced rubber hoses, as skyhiranger says.

thats because you either have the wrong cap, or it just bad we see that once in a while at our shop. if the hose pops back when you take off the cap its the cap, usally you notice it after the engiine cools down.

As soon as I take the radiator off you can hear the vacuum releasing and the hoses go back to normal

sounds like that cap isn't right- it should release pressure as the engine warms up(you have the overflow tank?), then let it draw back as it cools down.
