Hey everyone, I just bought a fun project car with a few overheating issues. The car's a 1993 Honda Accord lx sedan. It came with a bad TPS which needs to be replaced.My cluster's throwing up a Flashing D4. I thinking a code 7. New water pump. Prev owner put new radiator in it and works fine. The cooling system is not holding pressure and there is a coolant leak out the of the engine (popped freeze plug?) Could this be a freeze plug or is it something else? I have looked into it but I have gotten squat. I have also looked for a place to buy the freeze plugs but I can't find them anywhere.

To summarize. I just need to know if the problem of the leak/no pressure is a freeze plug or not, and if so, where can they be bought?

 

i think your best bet, is to verify where your leak is actually coming from. how sure are you that its a freeze plug? maybe just a leaking heater hose?

 

yeah check the heater hose on the passanger side of the car if you have the f22 motor the hose is put at a bad bend so it will crack if thats the problem do what i did get a slightly longer one and ease up the bend
