i noticed since i started using my air conditioner this season that hours after i park my car (01 tl ) i have a nice litlle puddle of coolant...i took it to the acura dealer and they did a pressure test and reported no leaks....im not an expert on this , but is this possibly a heater core leak... i would think that would come under a pressure test but again , it maybe seperate....it seems like if i dont use the a/c , i dont have any puddles....any feedback would be greatly appreciated..again its not leaking while the car is running but later on after its been sitting for a couple hours..

 

Are you sure it's coolant?

 

its bright green...... it is coming out of where the excess condensation comes out from the air conditioning....i guess it could be that the people overfilled the coolant when they flushed it and refilled it.

 

if it was a heater core leak you would have it inside the car or over by the passenger side tire area. If you recently had a flush they may have put too much in? Also keep a eye on the temp gauge to see if your overheating or something to cause the coolant to have to go to the overflow tank

 

that is where it is leaking....by the passenger tire area....thx for the info

 

i havent checked under the carpet but i have noticed it takes awhile for heat to come out of center vent...also is it a different test for a leak in the heater core, sine the aCura dealer said they couldnt find any leaks when i brought it last week..ive only had the temp go above normal temps on the gauge only once...thx for the feedback...im new here but have found alot of the info useful to avoid getting ripped off at the mechanic....thx alot

 

there is a heater valve in the engine compartment behind the motor, it may be coming from there

 

so one last thing...is this thing u refer too , something that wouldnt be revealed on a pressure test....like i said it something that leaks hours after the fact.....they said they couldnt find anything???? have a great day

 

?? Dont know??? If they pressure tested the system and didnt find any thing?? did they also inspect every thing?

 

i told them i was seeing coolant under my car and the invoice said pressure test that revealed no leaks via my local acura dealer......i have a friend that runs a very good garage...gonna call him tommoorow.
