I am going to start working on this this weekend, but I though I would get some input over the next 2 days on where to start. (might as well do somehting at work lol)
just a week or 2 ago, the ol' YJ starting running really hot after a bunch of city driving. It has been hot as hell here when it does happen but she has been through many summers and it has never been an issue before.
She used to run hot on the highway, but fine in the city, but since I put the 35s on, I don't take her on highways anymore so this stopped being an issue.
So now, when driving, i can watch the temp rise until I turn on the heat which works really well, but this obviously needs to be fixed.
The one time the guage was sitting at around 3/4 and I left the heat off since I would be home soon, the overflow bottle boiled over like crazy when I shut off the engine.
Since the coolant is circulating fine when the heat is on, can I assume that the water pump is fine? I replaced it a couple years ago.
Also, shouldn't this mean that the rad is fine? since there is flow?
I guess this leaves the t-stat. or fan clutch Anyway, just though I would get some input on where to start on saturday.
Thanks in advance.
