Leak on back of the engine

[dajoes90]

Hello everyone,

These days that i had my car parked off due that the front passenger window won't pull up and i won't have it fixed until this weekend, i've noticed a puddle of coolant every day and never gets to dry, and the car has been there for the last whole week and every day i've seen that leak. Any idea of what it can be? Long time ago, i've tried looking under the car and didn't noticed any hose leaking, looks like a heater core hose put i've been reading that it's really hard to replace them, what about using and a coolant sealant? Will that be a good idea?

No dont use coolant sealant, that's a stop gap measure best left for situations where you are far from home.
Also, its basically you giving in on correctly identifying the source of your leak. Coolant leaks are usually easy to trace. First, clean up the existing puddle, park up again, return later to confirm leak still happening. Leave car where it is, grab your flash light and get under there. Good luck buddy, you got this!
