Re: Problems overheating after long rides
I wanted to report back my results.
Last Friday, I did the full flush. This requires draining and filling your cooling system 5 times. Once to empty old coolant and put the flush compound in, three times to rinse out the system and finally to fill it back up with fresh coolant.
I am really glad I did it. After the first run with the flush compound, there was so much crud in the crankcase, that I had to get a piece of wire to poke through it to get the crankcase to start draining fluid. Don't want stuff like that flowing through your system.
It seems the biggest problem was a bad radiator cap. I went on two hundred mile rides over the weekend and no problems with the overflow line expelling any coolant. Only once did the engine seem to be running hot and that was in bumper to bumper traffic I got stuck on from an accident back up on the freeway.
I am going to keep monitoring the tempurature. With the one problem solved, I am a little suspicious of the tempurature regulator. I may pull it and test it if I still have problems with the temp dial on the dash. But unless that becomes a regular problem, I am considering this job done.
