Forgive me if this has been covered lately but I couldn't find it in a search. I have no problem day to day with cooling, but today for the second time I hit 230 F on a stretch of interstate with a 70mph speed limit. Had a stiff headwind and a trailer. Temp was 190 until I got annoyed at the OD to 3rd downshift on every moderate grade and pulled her into 3rd. This worked great but the temp needle started going up and stayed up until I backed off and shifted to OD. Just doesn't make sense unless high rpm makes the water pump cavitate. After a period of idling at a standstill, temp goes back to 190. No leaks.
Questions:
1. Is the lower radiator hose the suction side of pump?
2. Isn't the lower rad. hose supposed to have a spring inside it to hold it open? Mine doesn't.
3. Anybody had a similar problem?
I can pull the trailer all day and just tolerate the shifting or let the speed drop a little on hills and avoid the downshift and the temp gage stays below 200. I have a trans oil cooler and new water pump. Low speed idling and stop and go traffic do not cause this problem. Just when I hold it in a lower gear and wind it up a little it starts getting hot.
Thanks for any advice.
If I get an OEM hose will I get the spring with it?
