95 dodge neon heating and coolant system

ok... I had a leak that could not be easily pinpointed. It was recommended to me to use bars leak. Did so... and it worked for about 4 months. then started leaking again. So.. I did the bars leak again.. now... engine is running hot all the time, and I no longer am recieving heat.

I am guessing that the hose is cloged and would like a step by step fix for that... Please.

Thanks in advance.

if you have no heat either the heater core is getting plugged or the coolant level is low enough thats its no longer recirculating through the heater core if its overheating the coolant level will probably never stay full.
the first 2 components that would likely plug due to using stop leak would probably be the radiater and heater core suggest seeing a radiater shop if the coolant level is full and the cooling fan works.

The levels were very low this morning which makes me think the leak may not be fixed.....

so.. top it off and see if funtion returns... if not then probably a clog somewhere.. right??..

would expect the heater will probably work after filling but you still have the overheating problem to deal with wich could be caused by alot of things including leaks, cooling fan, thermostat ,clogged radiater would probably start with a leak test.

What are other possible leak points other then the head gasket??....

hoses.. duh.. LOL

but what else.. I pretty much pinpointed the leak...

it is just below where the hose comes off the bottom of the radiator into the engine. That would be the hose away from the thermostat (which I have already replaced).

if it appears to be leaking at the lower hose and you know the hose is ok its probably just running down onto the hose and may be leaking at the radiater, or if coming from the engine side often a leaking waterpump will run antifreeze onto the lower hose.

Pre-2000 model neons had a history of failing head gaskets, causing coolant leak and engine failure.

You might also check all the freeze plugs for rust (what it was on my 2000 neon)
