Ok, I just bought this 1989 Ford Ranger with the 2.3 Engine. The Seller told me that there was a blown freeze plug on the back side of the head...WRONG the coolant leak was on the exhaust side of the head..right underneith the metal pipe coming off of the exhaust manifold crossing over the top into the intake manifold. I can feel the hole with my finger, and its about a 1/2 to 5/8 inch threaded hole,,, Like some type of sensor would be installed,,,Is this some type of plug missing???
HELP ME PLEASE

 

can you put a pic up of the hole in question

 

well does your temp. guage work on the dash

 

That sounds like the coolant drain plug is missing.

 

good point

 

Yea the temp gauge is on the drivers side of the engine. The only thing on the pass side is the drain plug. You should be able to get one from your local parts house.

 

Thank you for your responce, This was the exact problem, I had to pull off the EGR Metal pipe to access the hole. Even Ford didnt know what this hole was.
Take care and thank you again
