Radiator level is probably low. Wait until cool, then remove the cap and check. _________________ 98 Riviera SC3800 All stock except gutted air box. 1970 Buick GS455 Stage1, TSP built 470BBB, 602HP/589TQ Best MPH, 116.06 MPH, Best ET, 11.54 https://www.youtube.com/watch?v=UHCda-t_Jls https://www.youtube.com/watch?v=sfT2tEO4XcU

| fairly common problem and the aftermarket actuators sold via Amazon are fine actually. Just look for them using the GM part number(s) on the sticker on your actuator. OR you can also just get the gear - there's a couple people who 3D print the things and also see https://www.amazon.com/Blend-Door-Actuator-Gear-Rebuild/dp/B01BKW3AKI/ref=sr_1_1_sspa.
Most likely installing one of those $13.- gears will 100% fix your problem once-and-done. | |

...dont overthink it, just replace the gears. used to be able to get the older actuators with metal gears from junkyard(out of 80s GM pickup trucks for instance) and swap the old gears into the newer actuators. not anymore really Albertj | |

| The plasticizers gas out over time, making the part brittle. The hole in the factory gear is a bit smaller than the metal cylinder it's pressed on to, that's what holds the gear in place when it's new, and what causes the gear to split when it's old. | |
