'94 Land Cruiser with 226K. Started running hot--near red line with RavenTai temp gauge mod. Mostly on the freeway but also around town.
I had already modded the fan clutch, but that was 50K miles ago so I got a new blue fan clutch and modded it with 15K (I think) fluid. No change at all.
After much worrying about a clogged radiator or head gasket problems I changed the thermostat (new Toyota thermostat).
Now: runs perfect, right in the middle of the temp gauge for normal driving.
Just posting this as very few threads pointed to bad thermostats. By the way, the old one looks perfect (not corroded or nasty)...
