With the alternator, you may want to fab up an idler pulley between the crank and alternator pulley to get the belt to wrap around the pulleys with more surface contact, then the belt won't have to be as tight.

Excellent!

UPDATE!

For those of you who may have been worried about the NAPA water pumps, my NAPA pump was not the issue! My issue was not the belt tension either which was a relief.
The actual problem was,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,

DOH!!!! The spring that I pulled out of another lower radiator hose about 4 years ago and put it inside of my lower hose made its way into the water pump. I bent the ends to try and keep it in place, but it worked its way into the pump.

I decided to replace the NAPA pump with the FlowKooler #1700. I also replaced the standard thermostat with a Moroso High Flow 180 degree unit (HF unit was recommended per FK), and I also replaced that spongy lower radiator hose with a Gates piece. The hot weather is returning this week so I will start testing out this new water pump.

WOW! I am surprised it didn't lock up or at least make horrendous noise!
Flowcoolers are great pumps, I run one on my 440.

No noise, just coolant spraying out of my hood and onto the ground.

clearly another case of cheap over-seas made garbage! oh, wait a minute....

Damn! Sounds like you are set now. If you do another spring (I would) be sure as you have already guessed to expand/curl it in the hose tight (er!). I would drill a very small hole in the stat (1/32" is plenty). helps greatly with getting air out/hot spots & lets you make pretty much a complete fill the first time & takes longer to select the bit than it does to drill it

After what this spring did to my last pump, I decided not to add another spring. I did replace the lower hose, but I dont want to take a chance of this happening again unless I see an issue with this new lower hose. The hose that I pulled off was very soft. This new Gates is stiffer.

I drilled my last 195 stat with 4 holes which may have been too many. The engine took forever to get up to temperature and I am now wondering if this was the reason why. I could idle it for 5 minutes and then after that, it would take about 4-5 miles of driving to get the engine up to temp. This new stat only takes a few minutes (5-7 minutes or so) of idling and the engine is up to temp. I did not drill any holes in this one because I have an overflow tank that makes filling the radiator very simple.

Thank for the replies.
