Coolant dripping from the rear of the motor
#11
If it's running down the back of the block, sorry to say but it's very likely the head gasket. I was in denial about this for the last few years until finally replacing every cooling system component (they were about due anyway) and then finally conceding and replacing the head gasket. Sure enough. The smallest weep out of the back coolant jacket. All cooling system problems have been fully solved since.
REPLACE COOLANT REGULARLY. The prior owner of our 2002 maybe replaced coolant once, and when coolant gets old, it becomes acidic and starts to eat away at aluminum bits (i.e.... your block) and will eventually chew right through the already anemic head gasket.

I live in the sticks so it's nice to be self sufficient. Plus it works on everything from pressure testing a carb, brake boosters, etc. If you can block it you can test if for leaks.

Found the culprit. I bypassed the tb cooler and the skinny hose coming from the top of the front intake manifold that goes to the coolant reservoir had a good leak. Hose clamp wasn’t tight enough. Also had a leak on same hose at the bottom of the coolant reservoir. Thanks guys for the ideas.😁

That line means the throttle body heater has been bypassed (and it was a TBH leak, of sorts). You can bypass it even more effectively by simple eliminating that circuit. Just plug the line at the reservoir and at the intake and be done with it. Plugging it = a short bolt stuck in the hose and secured with a small hose clamp.

The coolant flow diagram shows that the sole purpose of that coolant circuit is to supply the throttle body heater (labeled 6 and 7 in the diagram). If you choose to bypass the TBH there's no need for that line.
