I noticed a coolant leak. We had it pressure tested to see what we needed to fix. They said the thermostat housing was cracked. So, we replaced the thermostat housing & thermostat yesterday. Filled it with coolant & water & started it to see if it leaked. Within 90 seconds all the coolant was on the ground under the car. With all the wires & crap in the way we can't exactly tell where it's coming from. Where should we start? Please HELP! Thanks.

Did you replace the upper AND lower thermostat housing?
