I have a 1991 LS400 that I have put quite a few miles on 278k. Recently I have started to see a puddle under the right side of the motor by the passenger firewall. I am in wonder at what this could be. It in not leaking much about a pint every week and a half or so. I can drive 500 miles without losing a drop but once the car cools it seems to leak just a little. Any information would be of great help cause I do love this car and it does treat me very well as I do it!!!!!! It is one of the best cars that I have ever owned and will be getting my next one in several months.

Thanks
Alex

That's about where the air conditioner drain is located. Does it smell like anti freeze? If not, it's drain water. A normal occurance when it's a little humid...

If it does smell like anti freeze, the hoses for the heater core may weeping and need replacing.. A heater core leaking usually just leaks alot and fills the interior with fumes.

Have you noticed the fluid level dropping in the coolant reservoir?

The coolant is leaking but not on the inside of the car. Only the outside. The coolant level is lower when the car cools off it leaks then

coolant level always drops a little when you pop the lid of the radiator. its probly just your a/c when it leaks pull the car off of the water and check it
