1998 Accord 4 cyl, auto trans

I have a coolant leak on the gasket that is between the housing that the radiator hose attaches to and the front of the engine. The hose is fine and is not the source of the leak.

I need to remove these 2 bolts and replace the gasket. What is this part called?
The Haynes and Chilton manuals say nothing about this part.

Also, when I put this back together, what is the torque speck for these two bolts?

 

Honda Part # 19313-PT0-000

Aftermarket Part # Fel-Pro 35469

I can't give you the torque specs because I never use them.

 

WOW... so it it rubber?
When I was looking at it on the car, it looked like the paper/cardboard type of gasket.

OK, so as far as torque, maybe it can go to 25-30 ft lbs. If it leaks, then tighten a bit more?

 

I couldn't tell you I just do by fill. I would suggest to do it like you install spark plugs tighten until snug and do a quarter turn then go from there.

 

I don't typically use torque on these items and go by feel. The shop manual doesn't show a torque for these bolts. The thermostat housing torque is 8.7 lb-ft, so I'd use 9 to 10 lb-ft to torque it down.

 

It's like an O-ring, but the shop manual says that's only for the "metal water-outlet nozzle" which yours is metal. I guess they might have changed that to plastic sometime later??

It doesn't call out tightening torque, but I'd be inclined to use the same 12 N*M as the thermostat housing because I think it's the same size (M6) bolts.

 

Yea mine is metal for sure (1998). I plan to replace the gasket some time in the next few days.
Just getting tired of leaks. Last weekend I had to replace the thermostat, thermostat gasket, and thermostat housing cover. After replacing the thermostat gasket 1 year go, I decided this time to replace 3 parts.

Now this!!!.... Hope the water outlet is OK.
As for those 2 bolts, I am fairly sure those bolts are about 50% larger.
If I remember right, the thermostat cover bolts were 10mm. I believe the outlet hosing bolts are 13mm. I'll find out and post here...

 

M6 or M8 is the thread size, not the wrench size. If they're bigger, then they might take more torque. But really, the nature of O-rings is they don't seal any better or worse with tighter or looser bolting. As long as the metal-to-metal contact is good, and the bolts don't vibrate loose, it's good.

 

I have a 2000 Accord EX 2.3L VTEC (Coupe) and I am seeping coolant from the Water Outlet. The one that's on there is a black plastic material, but the replacement I got is metal which I got from Ebay (OEM). I had to purchase the o-ring separately from Honda. The metal one uses an o-ring, I'm not sure what seals the plastic one. I guess I'll find out when I do the job. Hopefully it'll fit, I don't see why not, every thing looks the same except on the plastic one there is no plugged sensor hole like on the metal ones,it is omitted all together
