ok my brother said he saw a puddle of coolant in the driveway where i park but when i looked in a spot the other day where i was park there was nothing not a drop... no leaks at all, yesturday i was on the highway and realized my heat wasnt hot anymore so i turned it off and back on and it worked for a bit then did the same thing, still no leaks when i got home that i know of. then i drove it today for five minutes and parked it, came outside 20 minutes later and a puddle of coolant with a stream coming out of the motor. i drove it to my friends house another five minutes away at running temp. no heat, and the temp gauge shot up to about 3/4 when its normally below 1/4(stock gauge, 180 deg. thermostat). pull up to my friends house park and no leak again... take him for a ride another five minutes still no heat, park in front of his house coolant streaming again.
