So I just got my LC back from my mechanic. I would have done the work myself but he is a knowledgeable Toyota guy and given my LC is a rust country sweetheart, I'll let him deal with the rust.... not to mention I am in the process of selling my place and all my possessions.
ANYWAYS.... When I dropped the LC off the coolant was brown. The overflow bottle was brown, the overflow hose was clogged with sand resulting in coolant overflowing the pressure cap. It was bad....REALLY BAD. According to my scan gauge I was running about 195-205F
Now, thanks to IH8Mud and the paranoia set in about poorly maintained coolant systems, headgaskets etc I figure that if the HG was going to blow...It would have with the heat and added pressure.
I replaced the waterpump, fan clutch to blue, new tstat, PHH, all other hoses, and switched to green coolant. Apparently when the block was flushed it took 8 full flushes with cleaner to come out clear. The mechanic said he had never seen a coolant system so absolutely nasty in 30 years. I asked him about the radiator and he said it was spotless....odd.
It's now running at 185-190
So...planning on an annual or bi-annual flushing now...
