I have a 96 blazer that is leaking coolant from somewhere in the back of the engine. When I tried burping the coolant system the coolant was leaking under the car from around the transmission. I have replaced the water pump and the t-stat. Any help?

 

The 4.3 is notorious for the intake leaking. It leaks out around the base on the intake and dribbles down the back of the block.

 

Thanks for the advice ill have to check it out

 

Sounds like an intake manafold gasket repair. I did this repair twice. I posted a thread about the procedure and tips if you want to do it yourself! Check it out

 

check the steel tube that connects to the intake for the heater. The plastic retainer and rubber in there could be shot....it's a popular place to leak

 

Tore down and replaced the intake manifold gasket. Had a little trouble getting the distributor timing right but when I did it fired right up. No leak and she runs between 194 and 198/199 when hot. Thanks for the help.
