Overheating Issue
 

My car keeps randomly over heating and seems to be losing coolant somewhere. The engine is a stock D16y7 getting close to 200k. Since the problem started occurring I have replaced the thermostat, coolant temperature switch, radiator cap, and I'm positive the radiator fan does in fact turn on. The overheating seems to be random and I cant seem to recognize a pattern triggering it. Also been watching for leaks etc. I'm out of ideas. Anyone have any further input on something I haven't checked/replaced/fixed yet?

I was experiencing the exact thing, turned out to be a small head gasket leak. of your losing coolant and it's not leaking then it's going into your combustion chamber or oil passage.

I was afraid that might be in the suggestions to check next

With that many miles, it happens. My civic blew the head gasket at 250-275k miles and my Integra at 220-230 ish.

Ya its been a trooper so far. Think its time to bite the bullet and just change the head gasket either way. That being said if anyone has any tips or knows a good write up for changing it that would be awesome

Anyone have good recommendations on where to have the head milled

I sent mine to AFM machining, it was close to me (west valley) Google them up they'll help you out

What did it run around if you dont mind me asking

My Y7 ran about 250ish plus Honda head gasket and intake manifold gasket and then I just used copper spray for the exh. manifold metal gasket

Milled, valve guides, valve job, and cleaning

Got the the same job ^ but for B seires, $300 if I remember correctly

Might not need to be milled, just a resurface should be fine.... Don't forget to ask for a new cam gear seal as well.
