1st I want to say THANK YOU AGAIN to everyone that helped me with the fuel pump issues that I had over the summer........ I really appreciate it...
Now, another problem..... My Blazer has multiple coolant leaks... it leaks a little when it is running, but when I shut it off it leaks a lot more in multiple places........ It is really hard to explain exactly where, but I will give it a shot......
Looks like it is leaking on the top of the trans towards the back of the motor don't think it is coming from the manifold gasket but cannot tell, also further back towards the middle of the truck also, it looks like the oil cooler lines are leaking..... also I noticed a little puddle of coolant by the thermostat housing.....
I really cant tell EXACTLY where the leaks are coming from..... and I know that I am not really giving a explanation on it...... BUT......if you can give me some kind of help I will really appreciate it.......

this could be your heater core lines leaking at the firewall...or intake manifold.
it looks like the oil cooler lines are leaking
oil cooler lines leaking is typical..the crimps leak eventually...
..... also I noticed a little puddle of coolant by the thermostat housing.....
this could just be your thermostat housing or upper hose...or intake manifold again.

wipe down what you can and then run it up to temp and check for new wet spots...or put a uv dye in the coolant to see where it is coming from.
the lines up above in red is what i would check first.

Thanks for getting back to me..... I will check what you have in red above and let you know what I find out... Now, the UV dye, can I get that at Autozone or Oreilys? If it is the heater core lines, how hard are those to change? I see you are in Bay City, I am in Sterling Heights.......
