Over heating, collapsed hose.
Some of you told me last year that I really should run a fan. I haven't been. Over the course of the summer temps have been rising on my gauge from the reasonable temps I was initially running while moving. I installed a pair of ten inch fans and it barely made any difference. Today I installed a milodon high output water pump, the high capacity 180 degree thermostat that Tim sells, and another 10" fan. (I have room for 4). Also ran some sulfamic acid through the whole system beforehand.
I found that my correct Stant thermostat was working great as evidenced by the pan on the stove test. The OEM water pump looked fine. While up to temp, I brought the revs up to around 2,000 and witnessed the lower radiator hose collapsing. WTF? I'm thinking that was the biggest culprit the whole time.
The hose is made in Mexico and is labeled 60995, also 078. It is shaped and fits perfectly, but has no reinforcement or internal spring to resist collapsing. Do most of these rigs sport non collapsible hoses? Where could I find a coil to insert into the hose? Where could I find a shaped non collapsible hose. Any one else seen this?

Apparently when hot and system is pressurized, the collapse doesn't happen. After some research , I've learned that this is kind of a controversial subject. If everything's cool with my system, I don't think I'll bother with an internal spring.

Yeah, I like it in here.
I get myself into trouble posting in the 73-79 forum, some personalities over there are just too much to deal with if I'm in the wrong mood.

So just now with a new 13 lb thermostat, the engine warm, and the upper hose hard and obviously under pressure, I had an assistant bring the revs up to 2500rpm and noticed the lower hose collapsing a little. Had him blip the throttle with the same results. I then got in the cab and blipped it perhaps a little more aggressively. The hosed collapsed completely. I checked the upper hose and found that the radiator was no longer under pressure. Does anybody know why?
