Hi Patty, I have a 93 Honda Accord which recently received a rebuilt engine. A few days ago, the radiator literally exploded (entire top blew off with cap). Before that happened, the check engine light came on (per mechanic code 02) and there were 2 times when the car had been on multiple short errand runs that it would not start for awhile and then it would start after about 5-10 minutes. I had a new radiator put in, left the shop, drove about 2-3 miles, sat in idle for about 2 minutes and the temperature gauge shot all the way up. Drove the car home and am concerned about being charged for multiple things before finding the true cause. Any idea what might be causing the car to run so hot when idling (seemed to actually cool down when driving faster) that the radiator would explode? Also, would this cause the car not to start intermittantly? Or the check engine light to come on??The air conditioning was also fixed and doesn*t seem to blow that cold (???). Any ideas/advice would be greatly appreciated. Thanks! Kim

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Kim, It sounds like your problem may have been a bad radiator cap. The cap is supposed to relieve pressure if it gets too high. If the cap is bad the pressure can build up and cause the damage you described. As for the new radiator problem. Make sure that there is no air in the system. They should have "burped" the air out before installing the cap. Air in the system can cause it to overheat. I would take it back and explain your problems and have them take a look at it. Your other problem may be that your radiator fans are not working properly. This is why it seems okay when you're driving, but overheats when you're sitting. This could also be the cause for the a/c to feel warm. If the radiator is hot it may be keeping the a/c condensor from cooling as well. The check engine light is probably related to the engine temperature getting too hot. If you fix your overheating problem it will probably take care of the check engine light as well. This light must be re-set by a technician. Hope this helps. Lori Johnson
