So far so good on my head gasket replacement. In the process I discovered that my PCV valve was shot and plugged up. After replacing that and the head gasket, I'm not using or leaking oil any where near as much. I disconnected and removed the AC compressor, since it didn't even have a clutch on it. Don't really need it anyway. I was thinking that I read somewhere that the AC fan is supposed to come on after the engine is shut off, to cool the radiator down. Is that true and is that only if the AC happens to be on at the time and if the engine is hot ? Or did I just dream that? Anywhooo ... I was wondering if it could be coupled with the regular fan and have extra cooling ... or would that be too much current draw on the circuit ? I suppose one could use a toggle switch and a solenoid to make it manual. It would be nice to have extra air flowing through the radiator for those occasional, long, slow, steep climbs up a mountain road on a hot day. Any thoughts on that?
