can anyone answer this.....
1991 f250 with a 460
Why am I able to remove the radiator cap when the engine is at operating temp?
I can unscrew the cap and the coolant seems to only be marginally warm.
I am having a stalling problem after the truck is warmed up and driven about 15 miles. It stalls and wont start until it sits for maybe 20 minutes or so.
The temp gauge reading seems ok ( I did notice today that it did climb to about the middle of the gauge but then dropped back down to what seemed to be normal)
About 2 weeks ago I overheated a couple times until I found the leaking hose ( on a aftermarket? Hose to a heater element) Fixed it and only problem was the thermostate got stuck I think cuz I had no heat..but then the heat started working again and has ever since.
Any help on this would BE GREATLT appreciated since this is my only "Get to Work" vehical and cant have this stall thang goin on

whats the condition of the radator its self? you might be losing flow which means less cooling, given the age. you might be due for replacing it. also have you done a cooling system pressure test? you could have a head gasket leak.

The radiator seems real good never had problems ie: leaks ect
I have not done a pressure test nor do I have the means to do it myself (tools) Unfortunatly at the time cant really bring it in either funds are real tight. I have some general automotive knowledge and am able to get basic tools wrenchs ect. The problem is diagnosing the problem. Im not even sure if it is coolant related (the stalls) Today after it stalled on the Highway ( of course!!) and wouldn't start, I found that the positive battery cable was real bad replaced it and it started.
Concerning the head gasket leak who knows ? again how to be sure ? The oil dipstick seems fine, oil filler cap residue looks as it always has also. Im not losing coolant to where I add any either.
In trying to troubleshoot this issue it seems from what info Ive tracked down that the "electronic spark control" module could be suspect also, given the fact that its maybe temp sensitive, thus the stalling when its warmed up?

very well could be the module. but what concerns me is the tempture not staying constant.as to testing the cooling system, autozone will do it at no charge, my 95 had problems staying cool, it turn out to be the radiator was plugged. have you pulled the plugs?what do they look like? fuel pump? when it dies, does it start right away? if not, try starting fluid, if it starts, then its fuel related, pump and/or fuel filter.

Okay.... So now I have changed the cap, the rotor, all new plug wires, thermostat.
Today while working on it, the truck was idling and it stalled. Luckly I had a helper, had him crank the truck w/the distributor coil wire off held near ground, I had no spark. 20 min. later, I had spark and she started. After i finished installing all the wires( when it stalled I had only put three new plug wires in), don't if that matters, but after all the wires were installed and the thermostat I left it idle over an hour. I took it for a drive and really pushed it, runs and sounds great like a 460 should, unfortunatly the lower after market heater hose that I have replaced was against the exaust and blew. So now I don't know if I have it fixed. I guess my question is, is could any of the things I have replaced could of been causing the no spark issue.
Thank you for any help, before I tear any hair I have left out.

The new cap and rotor was already installed when it stalled. I had only the remaing plug wires and thermostat left to install.

ok here is where my lack of knowledge shows thru... the module? is that the "electronic spark control" module that is supposedly mounted somewhere on the distributer ( for the life of me I dont where cuz i looked all over the dist) or are we talking about the "ignition module" that I think is that thing mounted on the passenger side 1/4 panel.. no wait thats the solinoid ? LoL or is it?
thats what this site is all about. also WELCOME TO FTE.

wait one other thing in my earlier post I said I had "spark" and it started I dont really know what a "Good Spark" should look like it certainly wasnt robust or a huge spark more like a little spark but was enough to start the truck..Im just trying to give as much info as I can here
