Ok guys. Heres my situation. I made the long drive down from tallahassee to miami with a slightly blocked radiator. The car ran at about just over 100 c until towards the end of the trip were it started creeping up at about 110 to 115. I ran it at that temp for just under an hour at a lower speed of of about 65. I get into miami and install a new radiator. I have just replaced the thermostat as well. Now it doesnt want to start. I have replaced the battery, the alternator and the ignition all very recently and when i turn the ignition all I can hear is the starter solenoid click. What do you think is suspect? Before I replace the starter what other mechanisms should I check? Is it possible that at that temp the engine might have siezed ( i wouldnt think so)? Thanks again guys.
