Sarah's issues
« on: August 26, 2008, 04:58:35 AM »
Ok, so mostly everyone knows Sarah, the YJ of all YJ's. Everyone know's the hard work and time I have put into her... and follow on plans for her, along with the fact that I haven't seen her in over a year at this point...

That being said.... I called Duantless the other day to get a status on her, see if there were any issues after the de-winterizing and initial startup. Well, here's the list.

- Yellow top Optima reversed polarity (showing -8vdc)
- Overheating like a big dog after 5-7 minutes at idle. (Mind you the t-stat is removed) Fan running, fluid full, pressure in system.
- Registration sticker never made it there from Louisiana.

Among other things that I can't remember right now. Not too bad for sitting for almost a year, I think. What do the rest of you think about the over heating thing, I'm thinking that the stock water pump isn't cutting it. I had a small issue with over heating when I was driving it (hense pulling the t-stat.) The radiator was brand spankin new, water pump same. The both of them only have maybe 1000mile on them... if that.

put the thermostat in.  It will allow the fluid in the radiator enough time to cool

After not driving it for over a year, maybe it just needs to be flushed. Also, like you said, a Hi-Po water pump is probably in order...Just my .02.

Oh, How's things going Brad???  ;D

I put a nice dent in my tcase crossmember and scratched some paint off my passenger door when my side mirror got knocked off and was swinging by the wires back and forth on the paint. Other than those two minor things I didn't take any damage at all.

So a nice tight trail then... I'm glad you guys had fun.

About Sarah, I tried the thermostat before. Not good. Plus really wouldn't matter at idle. I was thinking Rad cap too. That's what maintains pressure in the system, so lower pressure lower boiling point. Whacha think?

I was just thinking.  after 5-7 min, the engine would just be at operating temps, should not overheat by then. 

by overheating, are you refering to boil over or temp reading?  by boil over, it could be the cap (esp if the neeldle never reaches much above 220).  w/ a correctly operating cap (about 15#), the boiling temp is about 250F.

if you are refering to a temp reading, try using a infered temp gage on your upper radiator hose to compare inst panel gage w/ acutal temp (could be a bad sender or gage).  I can't think of a reason that actual temp will be too high after 5-7 min of operation from cold, unless your pump impeller has sheared off and you get a local hot spot at the sender.  if you are starting from hot on a warm day, it will have a tenency to be hotter than normal w/o a thermostat.  It takes time to remove heat from the coolant via the radiator, thats why you have a thermostat!  pulling it will cause high temps on hot days and low temps on cold days.  i did a through write up on how a cooling system works an earlier thread (pulling from my background of thermodynamics and heat tranfer/fluid flow).  Click here for a good write-up
