couple random questions

[cooljess76]

Hey guys, sorry to start another thread but I honestly searched and didn't find a definite answer. What temp thermostat shoud I get? Realoem says 95 degrees, while I've heard of people running 88 and 92 degree t-stats in the Ti.

Also, I just replaced my water pump. prior to replacing, the belt tensioner pulley was chirping. I tried spraying it with wd40 and greasing it, but the chirping wouldn't go away. Now that the new water pump is installed, the chirping went away. My question is, is the belt tensioner supposed to chirp by design to alert the driver that there's a problem in the belt drive system?
