Chevrolet Repair: 1986 chevy silverado, coolant level, chevy silverado

Question
Hi tom, i have a 86 chevy silverado and i recently noticed that it was running warmer than normal but never hot by the gauge. So i changed the thermostat and now i have steam coming from the exhaust. truck is running great, should i be worried?

Answer
HI CHIP, AS LONG AS THIS IS EXHAUST MOISTURE THEN THERE IS NOTHING TO WORRY ABOUT..HOWEVER IF YOU SEE THE COOLANT LEVEL GOING DOWN IN A FEW WEEKS OR SO AND NO EXTERNAL LEAKS FOUND AND NO HEAT FROM TIME TO TIME IN THE CABIN AND THE TEMP GAUGE GOING HIGHER THEN NORMAL,NOW I WOULD WORRY...POSSIBLE BAD HEADGASKETS..ONLY TIME WILL TELL. A [BAD] HEADGASKET LEAK WILL CAUSE WHITE SMOKE AND A SWEET SMELL FROM THE EXHAUST..BUT A SLIGHT LEAK YOU MAY NOT NOTICE ANYTHING AT ALL,, OTHER THEN THE COOLANT LEVEL GOING DOWN AS I MENTIONED ABOVE. JUST KEEP A EYE ON THE COOLANT LEVEL AND GAUGE.. GOOD LUCK TO YOU ,,,TOM..
