First, thanks to all overheat posters..I've read most of them over the last few weeks.
1996 Classic 4x4, UpCountry, Tow Pckg, no modifications, bought in 97 with 30k... now 232k miles. Daily Driver - 30 miles one way@70mph. 30 miles the other way half of it bumper to bumper on I-4. Temps go to 225-230 but E fan pulls them back to 215ish. Air temp doesn't matter 73 or 93 (current temps) it acts the same. Overflow reservoir level stays the same. No detectable leaks.
I have:
Back flushed
Prestone 3 day flush (will probably do this one more time)
New 195 t-stat
New Hayden clutch
De-rocked/straightened AC/Tranny cooler fans.
Compression test 180/178/162/175/180/180
Block leak test. Fluid stayed blue.
Vacuum test. 18/Champion OE plugs are light but not white.
New hoses.
New belt
Heater works great
Currently have straight distilled water.
In the absence of any serious symptoms I'm thinking it might be time to replace the radiator. Any other diagnostics I should try before proceeding?
