1)

2) What are the Diameters of your Damper, the Pulley you're using now, and the one you intend to use ?

3) "Maybe" at some point, you might try a 60a/40w% solution. There is a Tester for this, I think you are quoting volume, not % concentration.

4) Often times, a contributor to overheating is that the Fuel Mixture is incorrect for the altitude. Have you done a test for this ?

 

You don't have a lot to lose, in all but the coldest months

try a 75% water/25% antifreeze mix.

 

I haven't had time to touch it except for the day my wife took the keys with her to work, It shouldn't be too long before I can get back to it, but just in case it takes a couple weeks, I wanted to say thanks for the input so far.

 

No problem, we aren't going anywhere !

 

I drove it again today and had a chance to investigate the cooldown process. I'm pretty confident it is water flow related because I sprayed the radiator (with the engine at 215-220 degrees) and the water just rand down the radiator, no sizzle, no rapid evap. The little bit of water that splashed onto the intake manifold sizzled agressively and evaporated very quickly. I'm quite confident this is working in conjuction with the vehicle running too rich.

I also took a quick measurement and my water pump/fan pulley is 6"
Without burning myself I'm pretty sure the crank pulley is 8"

 

I'm just acknowledgeing your last post, but will add one thing...

When all this is settled/fixed, you'll probably need to do a good Clean/Flush on your Cooling System.

 

I agreed what is said above!!!
I am also facing the same problem with my chevrolet. I read out interesting and informative ideas. This will be helpful for me in this regard. thanks everyone...

 

That's a bunch of crap, I don't think you even own a car.
What's this, about the 10th time you've re-registered here !

 

Sounds like a clog in your cooling jacket. Find a garage with a large

power-flusher. Many times gunk, or a rusty radiator hose spring gets

caught in the engine side, causing the problem you have now.

 

That's great, I didn't think of that!
