Hi Rob...

Saturday I put the newly flushed rad in and installed a 160 degree thermostat (remember it did not have any on taking off thermostat housing).

So, here is what happened on start up......the jeep cranked but would not start....usually it starts first crank....I panicked. Did not know why it would not start. Then, I traced back to what I did before the rad flush/thermostat install.....I installed a second fuel filter on the line underneath the rad....first one was in between the carb and sediment bowl....so, I took off the filter near the carb and left the new fuel filter before the fuel pump.....jeep started first crank!

Question #1.....did the two fuel filters make it hard for the fuel pump to pump fuel to carb or what?

Secondly, once the jeep started, I had my wife sit in the jeep watching the temp gauge....I was watching the open rad to see if coolant level dropped on thermostat opening. (Remember initially on checking the thermostat- there was none on taking the housing off-with no thermostat in the jeep temp gauge never went past 140 F) so now, with an actual 160 F thermostat installed, after about 20 minutes of idling (had to recharge batteries) the temp gauge very slowly went to 180 F-but never moved past 180 F parked in my garage but the coolant in the rad-at the rad cap opening never went beyond 155 F (measured by a new rad temp gauge)-never triggering the opening of the 160 F thermostat....Question...is this normal?

Thanks in advance...
