Preciate it man. I bought the XJ this past winter for fun and snowboarding trips, etc. And being at as low of miles that it was and being owned by a marine I had assumed something like this wouldnt be an issue.
Is my T-stat the reason why heater wont work? When I get up to op temp this is what its showing:

djb383 is quite right...before you put in a new rad, open that puppy right up and run a hose in it until it looks like you could drink the water (looks like...please don't drink that water!). You have an awful lot of sludge in your system...I''m not surprised you have cooling problems.

Alright guys, To The Top.
Got the HD 3row Rad, plan to install that, but before doing so, I did my research. Im gonna just replace everything pump, hoses, tstat, reservior, etc.
Was looking at FlowKoolers pump p/n 1747, any input?
As for the T Stat, 180 or 195? and which manufacturer? I live in Charlotte area NC so average winters, nothing too extreme lows at worse case round the teens or 20s. And summers July gets high 90s with 70-90% humidity

FlowKooler is crap trust me, you will have a problem with it hitting the inside of the engine block. Go with Hesco. As far as the tstat go with Mr Gasket 180F it's the best.
If you want pictures I have them in my album on my CT profile.

With a big rad, 180 t-stat, new fan clutch and hi-flo pump, I would think u would be below 210 most of the time. Triple digit ambient temps will test any cooling system. The dash gauge is just a indicator and not known for being accurate. If u really want to see what's going on, plug a scan tool into the ALDL port under the dash.
