I recently put a rebuilt 258 in my 85 CJ7. It was performed by a local shop and a new water pump was installed at the same time. After i got everything back, i went ahead and installed an autometer electrical temperature gauge so i could see exactly what i was running at.
Driving around town, i'm sitting pretty constantly at 210. My sending unit is on the drivers side of the of the engine block right near the firewall. EGR is hooked up
However, when i get going at a good speed ~60 or so, for any period of time, the temperature starts to creep up. After a brief 5 minute drive at that speed, i was already up to 225 and climbing.
I'm assuming the thermostat is working (and new), because when it heats up around 210, i can see it move back a bit telling me the thermostat has opened up and coolant is flowing.
I have what looks like a 6/7 blade fan (not sure if it's a clutch fan or not). Shroud is installed.
I'm really scared to take it on the interstate for any period of time. Prior to putting in the new engine, my last motor overheated on the interstate and boiled coolant everywhere!
I'm thinking it's the radiator perhaps, but i'm not sure. Also i have a warn 8274 up front which sure isn't helping the air flow.
Ideas? bigger radiator?
Thanks!
