Anyone on here ever flush coolant on a 98ish Oldsmobile Silhouette, aka Chevy Venture? I attempted to do so on my sisters van and was the most difficult coolant flush I've ever done. You can't fill the radiator via the radiator it has to be done through the reservoir. Although I found the bleeder screw in the thermo housing after the fact so could be possible after all. Finally resorted to filling the reservoir and applying vaccum to the bleeder screw. Took forever and a day. I'm I missing something there has to be better process.
On top of that I couldn't use the radiator petcock. It looked like the radiator was cracking around and didn't want to chance it. Pulling the lower radiator hose is only fun twice. And it did have the intake gasket problem but didn't look bad considering. Has 208k on the odo.
