Mike there is a way to check it for leaks while cold. Any garage should have a pressure Tester, even I have 2 of them and I am a draftsman. Anyway, a pressure tester can check the system for leaks and also check the cap to see if its working properly. Are any of your friends or neighbors car buffs or backyard mechanics? Maybe they might have one you can borrow. Easy to use, ,,,,,,remove the cap, place tester on radiator and pump it up to maybe 16 pounds , watch for leaks. The tester should remain at 16 pounds, if it drops and you don't see any leaks there could be internal leaks, but that does not appear to be your problem. Hope this helps....Happy 300'ing Charlie Valentine ----- Original Message ----- From: MJMLandDev@xxxxxxx To: Chrysler300@xxxxxxxxxxxxxxx Sent: Sunday, November 11, 2007 10:41 AM Subject: [Chrysler300] Radiator problems I need someone with a real good imagination. Last night I went to a cruise-in down in New Smryna Beach. I opened my hood and everything was fine. About 15 minutes a guy comes up, asks if this is my car and tells me I have a serious radiator problem. So I walk up front and here is my bumper and grill covered with all this green crap (antifreeze)! And there are indications that is shot out thru the grill because there was a stream of antifreeze that left a stream of antifreeze 5' from the car. In front of the condenser were more indications of antifreeze. So I checked the radiator. It was down so I added 2 liters of water (didn't have any antifreeze there). I left and went home and watched the temp gauge the whole way which never moved above it's normal operating temp. This morning I checked the radiator. It's at the normal cold level! Thinking that just maybe what I saw was freon I fired her up and turned the A/C on. Plenty of cold and only a couple of bubbles could be seen in the view finder. So the radiator is at it's normal level now. The A/C work perfectly. Any ideas where yesterday's antifreeze might have come from and why it no longer leaks?
