Coolant

[Max Hoepli]

steam rises at front left of car.


Could leaking at an upper corner.  Follow the steam vapor you can see
rising.  Another alternative is a small leak in the head gasket but you
would be seeing elevated running temps.  Also could be the heater core
leaking.  Had that on my '87 5kcstq.  A pressure test (where the overflow
coolant cap is replaced by a hand pump to pressurize the system).
