Replaced the serpentine belt this weekend, went on pretty smoothly, seems like it's the right tension, but this morning after arriving at work I noticed a small leak from the radiator cap. Could it be related to the belt replacement?
Probably not. Take off the cap and check to make sure theres no gunk on the gasket or the radiator neck flange. Is the coolant bottle showing hot level and cool level when appropriate? Any different temp gauge reading?
Definitely didn't hit it with a tool. Temp guage reads normal. Coolant bottle looks good, was a little low at cold but not down to the add line. I'm a pretty tall guy with long arms so I was able to get in there pretty easily and replace the belt so I doubt I put much if any pressure on the radiator. The belt seems like it had the right amount of play in it but I went ahead and loosened it up just a bit. Drove it home and back to work the next day with no leaking so it may have been just an anomaly. Guess I'll just keep an eye on it for now.
