xShodaimex Posted November 23, 2009 Share Posted November 23, 2009 Right when i thought my problems were over, another problem arises. Once again coolant is leaking from the engine. I have not had time to check out where the leak is coming from but it seems to be leaking from somewhere near the back of the block.. not sure what it is but I will let you guys know of my progress tommorrow..last time it was my water pump gasket, once that was sealed tight, problem was over. if you guys have any ideas of where to look or what to looks for please tell. thanks:burnout: Quote Link to comment Share on other sites More sharing options...
Mayolives Posted November 23, 2009 Share Posted November 23, 2009 Coolant leaks, especially external ones, are easy to find with a little patience and a pressure tester. Don't over do the pressure when you pump it up. Ten pounds should do the trick. If it's internal, you will need to dig a little deeper and ask better, and more specific questions.

oldschool2 Posted November 24, 2009 Share Posted November 24, 2009 My leak was from a heater hose failure. If yours is bad you can put a new hose on the engine to heater outlet and loop it to the heater to engine intake. You will have no heater but eliminate the hassel of digging into dash. I think it is a 5/8" hose, not sure. Same works for a heater core problem. Quote Link to comment Share on other sites More sharing options...
xShodaimex Posted November 24, 2009 Author Share Posted November 24, 2009 hey guys thanks for the advice.. so far, i only had 30 mins to check it out and so far not much has happened. I noticed that the leak is a very slow leak. i also noticed that the coolant in my radiator slowly goes down. Im hoping to have more time tommorrow after school to check it out, but wont actually get to have a good look until thursday because of work. I actually dont have ac or heater so would i even have a leak from the heater hose? btw stopped by my local harbor freight store and pressure tester was 70 bucks i think.. wow.

oldschool2 Posted November 24, 2009 Share Posted November 24, 2009 (edited) Regarding heater hose: Generally, to the right rear protion of the 280zx engine are two fittings (in and out) for hot water to enter/exit the heater assembly. I would expect that yours are capped or may be already looped as noted above to bypass the heater. Possibly there is a leak in one of the two provisions.
