My 1965 dodge polara is leaking coolant. Fortunately it is a very slow leak, but the problem with that is it is very difficult to precisely locate where the leak is coming from. I believe it is coming from the back of the engine block. I have heard that it may be a freeze plug. Anybody have any ideas what else it may be, and the best approach to fixing the issue? I'd appreciate your advice.

 

theres freeze plugs on the back of the heads and block, they are both hard to reach will the tranny or engine is in, if it is the freeze plugs id pull the engine and replace all of them. it could be a cracked block, bad gasket, hose,

 

have u ever change the exhaust on the car before? the only reason i ask is i change the exhaust on mine and put headers on it and each one of the header bolts had to have a dab of silicone on them cause i a had a coolant leak also

 

check the hoses to your heater core, you might have a slight leak at the fitting, found one on my upper radiator hose this weekend. little tiny hole.

 

Prob a freeze plug if theyve never been replaced. If you go that route, like Mr Fury said pull the motor and do them all.
