I feel like a stupid *** for asking this question but where is the bleeder screw for the coolant system. It's an '88 HB standard converted to multi-point. I changed the thermostat and now I can't find the bleeder screw to bleed the coolant system. Thanks

 

Follow the upper radiator hose to the cylinder head. It should be looking right at you.

But just a note, I have seen some D series heads without a bleeder. Just take the radiator cap off and bleed the system that way. Raise the front of the car up slightly if you want to get fancy.
