I'm getting a Haynes tomorrow because i hate asking dumb questions. What is this and why is it unplugged and theres two hoses that are going nowhere.

Also I'm leaking coolant from the thermostat housing bad casket time to change. Should i get one from the dealer or is there one just as good for cheaper.

 

If I'm not mistaken, that port is supposed to be left open to atmosphere. Why there would be hoses on it I don't know. Should be just an open port with nothing on it.

Thermostat gasket you can get anywhere- it's still just a standard SBC thermostat gasket- nothing special needed.

 

that's your air canister, part of the sniffer test pre-requisite... I'll post a picture of mine in a few minutes...

There is a plug that is not plugged in on top the other end is wrapped in tape why would that be unplugged. I want to plug it in but i don't now what it is for.

 

is your car running like crap? You will need the emissions diagram.. I am not sure if the Haynes manual has that... Previous owner may have plugged the vacuum lines...

 

I see so i can remove the hose if i want but yours is different theres no box at the top that you plug a plug into i will post a better pic

 

I meant the thermostat if I'm changing the gasket i should change the thermostat. I was talking better brand ,temp, like a 180 do these cars run hot in the summer. Or stick with the 195 i drive her in the cold temps sometimes 30 degrees never in snow

 

180 should be the lowest thermostat temp you should go with... btw.. what year is your car? I have access to the vacuum line diagrams...

 

the diagrams are 87-89 and 90-92, check the name of the file for your model year...

 

Nice job on the pic mine is the second one i will be saving this pic thanks. So the purge solenoid is disconnected i take it this isn't needed.

 

anyone have diagram for 86 iroc-z?

 

never mind i found it
