Out of curiosity, anyone have a picture of the cooling system diagram? I would like to see the path of all the little coolant hoses.

THanks

 

Search for the FSM (Factory Service Manual). Plenty of places online to get it. And then not only do you have the coolant flow diagram but also every other diagram you could ever want for your car.

Actually, I'm sure the thread on this forum pointing to a site hosting the FSM still exists. Search feature. GO GO GO!

edit: Here ya go. http://www.hi-impact.org/ryang/modif...8_manuals.html

 

It's not a very complicated path. Basicall a loop between the condenser, compressor, and evaporator, with a couple of valves for adding/measuring refrigerant.

 

I think he means the Cooling System not Air Conditioner Cooling?

 

The cooling system. THje shop manual is useless, it gives you the diagram of the big hoses. I am interested in the heater hoses and the little hoses.

Thanks

 

bump anyone have such a diagram?

 

There are a lot of entry/exit breaks in the system

one heater connection on lower left side of rear housing and then the metal tube line that runs on the firewall behind the engine and the other line connects near the t-stat (attachment #3)

one throttle body connection near the t-stat and the other connection point is on the top right side of the rear housing behind the intake manifold (hose runs underneath the UIM - attachment #5)

the rest is pretty straightforward, but feel free to ask if you have any questions

Anyone know where to get a replacement heater hose ? Ive searched and nothing. Its the 61-213 on the third diagram I believe. Im uninstalling my racing beat gauges and the water temp sensor adapter is there.

Thanks

 

FE01-61-213 Hose $5.90

Thank you kindly

 

Regarding the hose that runs under the UIM. Does anyone have a part number for that? And where I could get one I know this is an old thread just trying to figure out where my leak is and is seems to be coming from underneath the UIM.

 

Bolk heater hose of the same diameter and length will work fine.

 

Good to know! Hopefully its that hose and not something worse :/ the smell is terrible it doesn't leak much but it steams a bit (especially after spirited driving) and when I've got the vent on it gets all in the car. The coolent temps haven't been effected at all though.

 

Bumping for a question.

What purpose do the two little hoses on the rear of the coolant expansion tank serve? There is one that feed below the Tstat and one that feeds above. Some type of bypass? Does the larger of the two allow coolant to pass through to the engine when the thermostat is closed?

 

Anyone?

 

i think it is for re circulation of the coolant?. i mean some cars have just an expansion tank, some have the tank that can also recirculate the coolant to the engine.

 

The other day I was doing some studying and 've made these comprehensive schematicd diagrams, I think it's nice to share them with others.

never saw 9k’s question from 8 or 9 years ago, but for future reference they’re for allowing air to escape out of the coolant system into the air chamber in the expansion tank. That’s the main purpose of the tank; to separate air from the system and indicate the coolant level to maintain it that way.

Almost forget to post the right handed version

 

isn’t it essentially the same thing?

Essentially and technically yes! Apart from the heater core sits on the other side of the dashboard, firewall connection, a few heater core hoses, water direction on toper metal pipe.....
Having "Restricting Valve Orifice" is hit and miss by the year of production and the imported market as far I understand.
