I try to start the RX every week or so durring the winter since it doesnt get used. Started it the other day for about 10 minutes or so and all was normal and then I shut her down. Come out the next morning and find this puddle of coolant in front of the car and a small nut in the middle of the coolant. Looks like the coolant originated somewhere by the front drivers wheel. Have not had a chance to investigate but figured I would post a pic of the area and the nut to see if anyone happens to recognize it and where it comes from.
Thanks,
Ali

 

whatever leak it is, is probably wicking there and dropping down. possibly across the undertray. i would just check the usual spots for leaks.. hoses, water pump area, ast.. if the nut is related at all maybe it was part of a tiny t-clamp(do they make them that small?? lol) that used to hold a hose.. maybe uim. quick disconnect could also have a leak.

 

Check the 14mm drain plug bolt on the driver side of the housing and the heater supply hose on the same side to the rear. Nut has nothing to do with it. Hopefully you had the correct antifreeze solution ran for your weather.

thanks guys, will check those spots.

 

Report back on root cause...

Its leaking right below the heater hose quick discinnect!

 

thank for the help guys, quick disconnect looks fine but once I pulled it out into the light I think the AST is definitely the culprit.

Guess its time to get a metal one.

 

Good eye ! Common failure on our cars. Options - 1) Go with an aluminum one or 2) eliminate all together.
