I don't know if this has been posted before but I'm having trouble locating a leak that is causing excessive coolant loss and overheating. It started after a couple 4 hour trips And some playing around on the freeway with other cars. Noticed when I got home car started overheating so I added more coolant. Fixed for a little but after letting car sit for a day I noticed a puddle of coolant coming from drivers side by front left tire. Was told it could be hoses going through firewall because I had some fluid on my gas pedal area. Any ideas?
Checked all my radiator hoses and no fluid on them
Looked under car and its coming from the area near t case but cannot see/locate where the leak is coming from. Thermostats area is dry too. Any ideas?

 

You should have 2 lines going in and out of your firewall (to heater core). Hope that is it and not the heat core itself as it's more of a pain to replace.

 

pray its the 2 rubber lines in the engine bay and not the heater core leaking. if you have a puddle near the gas pedal, you didnt pray hard enough.

 

check the waterpump tree in the back under the intake mani. its either the heater feed or the throttle body coolant loop. either way look between the battery and the intake manifold.

 

Just remove the battery and you'll see what's going on with your coolant lines that goes in/out thru the fire wall.

 

I found several coolant leaks by parking the car, opening the hood, and reving the motor. If its aleak in the engine bay, you'll find it nearly instantly.

 

here's a pic of the coolant line's. I just replaced mine.

The highlighted spots..check those out on your car. It could also be that your car's coolant lines have cracked in general and a leaking from any point on the line. Best to replace soon.

 

^ Wrong lines. Those are going to the engine.
The OP may have a leaking heater core if there is coolant inside the cabin. If he is lucky it may just be the 2 feed lines to/from the core.

 

I'm sorry I read this incorrectly. whoops.

 

If you have fluid inside the cabin it has to be your heater core.
