| Coolant Leak on Ground - Passenger side (Page 1/4) |

86GT V6..
I have a coolant leak dripping on the ground, passenger side about a foot or so inline with the back of the tire. As far as I know it's not leaking inside the car on the carpet - just on the outside. It drips more with the front end jacked up (once about every 10-15 seconds or so).
Is it possible the heater core is leaking on the ground without leaking on the carpet? I checked the pipe that runs from the back to the front and that is dry.

"the tire"... the front tire?
If the drip is in the front of the car... obviously check the radiator, overflow tank, and all associated hoses and connections.
A leaking heater core will drip inside the cab... onto the passenger side carpet.[This message has been edited by Patrick (edited 08-31-2021).]

I should have clarified this.. yes it is inward about a foot from front passenger tire on the rear of it...
It primarily drips more constant when raised up and I can't tell where it's coming from. The passenger side floor is slightly sticky but no puddles or severe dampness and no fogged up windshield or window. I just had a coolant flush, so it seems there would be a lot of water on the carpet if it was a heater core leak.
Is it impossible for a heater core to leak coolant on the ground? I could very well have 2 leaks for all I know.[This message has been edited by Brent7088 (edited 08-31-2021).]

That was my initial thought too, but I wasn't real sure where the water pump is installed on an 86 GT.. I thought it was near the alternator.

Nothing is "impossible".... but seeing as how the heater core is inside of the cab, I'd say it's pretty unlikely that a heater core leak would get to the outside of the car... unless it's seeping through the floor! 
Take the cover off of yours and have a look. Here's the cover off of my '86 with A/C (as non-A/C is a little different) when it was leaking.

It sure as heck isn't anywhere near the front of the car!

Looking at the photos i now see your gas tank is all wet. The heater lines pass by there to the front.

Thanks Patrick - I'll take a look tomorrow... sure hope that thing isn't what's leaking.. I have AC too and I know how much of a bear it will be to get those inlet/outlet hoses off the tubes.

Yea, not sure if that's runoff from the initial coolant leak or what, but it's not gas. I'll just take a look at the core tomorrow and crawl underneath for more hidden leaks.[This message has been edited by Brent7088 (edited 08-31-2021).]
