What size is the bolt the secures the thermostat housing on the LS1 water pump? There are two (2) of them and I stripped one of them and need to heli-coil it.

What size heli-coil does it take?

Cheers!

Thanks man, is this the right Heli Coil kit to repair it?

That's it... It would be better if you remove the pump and do it on the work-bench. If the pump is old, you can just replace it and that will fix all your problems. The thermostat/water pump inlet bolt torque is 15 N·m (11 lb ft).

The pump is used but I rebuilt it, its a Meziere electric pump and I replaced the o-rings and had it painted, I also sent the motor back to Maeziere for a free motor/pump evaluation. It's installed on the motor but luckily the stripped bolt is on the top / outboard side so I can get to it fairly easy.

Thanks for the help bro!
