navion Posted February 13, 2005 Report Share Posted February 13, 2005 Hi guys, 1994 SLS It seems that almost every hose joint that uses a clamp has leaked at one time or another. I'm beginning to wonder if my surge tank pressure cap is defective causing the pressure to be above the specified 15 lbs. I replaced the radiator & the waterpump & heater core over the past couple of years. Also new hoses and thermostat. When the system is full and not leaking at a hose joint, it maintains temperature just fine. The only thing that I haven't replaced is the pressure cap. I guess that is next on the list. I have never had a cap fail to the high side before. I guess that is why I haven't replaced it before now. Anybody have any thoughts on other causes of hose clamps backing off or other causes of this? I have never had a vehicle that seems to develop leaks at hose connections that this one has. I originally wrote this in a reply to another post, I thought that would treat it as a new post. Thanks, Britt Britt Link to comment Share on other sites More sharing options...
