can anyone tell me where the air bleed plug(s) for the cooling system are on the sr20de models?
i bought a haynes manual, but it seems to focus mainly on the ga16de.

Small nipple on the firewall, it's an appendage off the heater core hoses. Attach a hose to it, route it into the overflow tank. Why are you asking?

Isnt there one on or near the thermostat too?

The B14 only had the one on the thermostat housing, at the 1:00 position.

Searching is very useful..........

There is also one on the front of the block, but in my opinion that one is a waste of time. WHen you fill the coolant leave the bolt out of the thermostat. Fill till coolant comes out of there. Then continue filling till coolant comes out of the nipple on the firewall. Then you shouldn't have any problems. Obviously run the car and contiue to add fluid till the reservoir is to the appropriate level and coolant is to the neck in the radiator.

I'm wanting to know because I need to change my coolant.

I looked for the one on the firewall, but couldn't find any? I found out from a website that the 92 SE-Rs had this bleed valve, but are you sure my 99 sentra has one? The book only tells of the one on the thermostat housing.

GSRMx: Guess what? Some things change from year to year and model to model. I had already seen that page and looked for the valve near the firewall. I couldn't find it or any info about the 99 sentra, so I posted here. Searching wasn't very useful in my case.

yes I know, and there are a *lot* of posts about this thing. The upper cap is gone from models 94 and up.

thanks
