Replace my radiator last week. Took me about an hour. Thanks to 'SW' I was able to find the block drain plug (19mm) as he described and was able to flush out the block with a lot of water.
One mistake I made was not to install a new reservoir to radiator hose, as it is getting old. The old radiator fins were choked full of everything. I guess I could have gotten away with just installing new tanks. With the new radiator installed, normal operating temp is 90C degrees, but in stop and go traffic up Hwy 17 in 95+F temperature with the AC on, the temperature moved up to 110C in a short time.
I know the AUX fan works correctly, but it does seem to turn the wrong way, ie sucks air out of the engine compartment.
Thanks again to everyones advice.
