R 129-119engine temp/belt tensioner FYI

[pollockd17]

My 500 is a 91 with 92,000, The temp has always run around 100C in the
summer. My tensioner gave up the ghost and had to be replaced, and now
I notice a 10 to 15 degree drop in the temp, so even with the proper
adjustment there must have been slippage because the rubber in the
tensioner was softening up, so now there's one more thing to keep an eye
on..............
