Yes, I've spent weeks trying to figure this out - and yes, I've done extensive searching on the forums, I just can't find someone with my EXACT issue lol, so here goes:
I went to Asuza a few months ago in my ’88 XJ, and busted quite a bit of stuff. It overheated, I blew the bottle and lost my idler pulley and alternator.
THE ISSUE: I had put in a new radiator a few months prior, the thing is in top shape. I replaced the coolant bottle and cap, and t-stat after the horrible mud pit experience. Did a refill/burp process, and I was still overheating. Upon closer inspection I found the radiator was pretty caked with mud, so I took a hose with a power attachment to it, and most or all of the mud came off. This fixed my “overheating” problem, but now it runs at a consistent 210 whereas before it ran at the FIRST line (I assume that is around 160). I know they say these are designed to run at 210, but I sure do not like it.
THE ODD ISSUE: My XJ will idle all day long at a decent temp, the minute I hit the freeway it jumps to 210, and if I encounter a hill, it can shoot up to around 220 in no time. This tells me it is probably not the clutch fan, as the fan does not really make much difference at 55+ anyhow. The electric fan is working and comes on RIGHT at the 210 mark, the relay works consitently, and it appears to have no issues. My suspicion is a coolant flow problem, but how? From where?
THE QUESTION: When I pop the cap to the coolant bottle when the t-stat is open, I get sort of a steady stream of water, but it’s little more than a dribble from what I would expect. If I’m looking at the hole the coolant enters the bottle from, the fluid might land ¼ inch away from it, and I believe it should probably shoot out a bit more. Also, if I squeeze my radiator or heater hoses, I can’t really feel much going on. They are hot, but very easy to squeeze. I have not replaced the bottom radiator hose, but it does not appear to be collapsing.
I’m know a good coolant flush can’t hurt, but I was just wondering if anyone else had the same or similar issues, and what they did to finally solve it.
OH, and btw, my t-stat is drilled, system does not appear to have air in it, although with my luck anything could be happening.
