Car: 1985 Pontiac Firebird Engine: LG4 305 (originally 2.8L V6) Transmission: 700R4 Axle/Gears: 10 bolt 3:43 Open Diff. | Smoke question | Is it normal for white smoke to come out of the heat riser when the car is extremely hot. Drove about 2 miles, popped the hood and there was white smoke coming from the heat riser while my radiator cap with the temp gauge built in said 160 degrees but I have a feeling it was hotter than that. | | | |
