Default 2004 Blazer V-6 running too hot, Help.

I have a 2004 Chevy Blazer and it runs too hot.
Its always right on the edge of pinging and has no power.
I'm 47 and from another era as far as working on new cars.
Help.

Isn't that still under waranty maybe?


Check the oil for coolant....Check the coolant for oil....Maybe go get it all flushed and go from there. Could be something as simple as a stuck thermostat.

Thanks for the info guys.
Its always been running in the 200 range since new. The salesman said all Blazers run hot. I've been playing with cars since 1965 and never have heard anything like that.
I think it might be some emissions thing.
What do you guys think about these PROM chips?
I know how to set a solid lifter set up or adjust a dual point distributer but these new cars seem so complicated.
Thats why I thought I'd ask some fellow gear heads.

OEM Thermostat opens up @ 195. my neighbor'* bravada quickly rises to 210, and just stays there, unless it sets for a while on a hot day. i say its normal, unless you are not complaining about the 200 degree temp, but something higher...

It seems to me that 200-210 is too high.
When load is applied to the engine its always seems to be on the brink of pinging.
I'd like to try the 180 but I'm wondering if it will pass emisions.
This truck only has 10,000 miles on it and it seems like it should have much more power. My buddies V-6 Electra is so much more powerful that this Blazer.
Its just like the Bravada you mentioned.
