d16a6/z6 coolant problem.

By 92civic_vx
- Sun Jun 03, 2012 10:28 pm #307190 i have a d16a6/z6 minime in my hatch, about 2 months ago i replaced my thermostat due to my lower hose sucking itself in and no heat. everything has been good until friday on my way home from work it started to get a little hot. got home and let it cool off then opened my radiator cap and it was empty but my overflow bottle was soaked and filled to the top. :? i am wondering if my HG is leaking. oil is good no coolant mixed in it, coolant is clean no oily residue found. i replaced the rings and all gaskets on the engine about 3k miles ago. could it be possible that the HG would cause all my coolant to be forced out to the overflow?

- Tue Jun 05, 2012 3:23 am #307367 Could there be a leak anywhere else that would allow air to enter your coolant system? Maybe water pump, thermostat housing, old hose? If you're losing coolant and allowing air in the system, that creates an air pocket which will prevent coolant circulation, leading to the coolant getting too hot and boiling over into the overflow tank.
