Hey guys, I just purchased a 97 RS 3.8L manual transmission. I’ve looked at all the radiator hose diagrams and can’t tell if my hoses are hooked up and routed correctly. I have an open inlet plug right under the radiator fill cap. Any help is appreciated.

 

should be a coolant level sensor there for low coolant indicator. do you have a wire there not hooked to anything

 

Unfortunately no there is nothing there they had a hard line hose there before that went to the AC with a sensor but it was broke

 

According the diagram it doesn’t appear there is a hose that is connected to this port. Is it supposed to be capped off?

 

that hard line should go to the ac condenser in front of the radiator

 

yes I see that now thank you. I’m still interested in the line that is supposed to go to the inlet just below the radiator cap. It appears in all the drawings nothing goes there. Maybe it’s supposed to be capped off?

 

that radiator may be for a auto trans, it may be for trans cooler.

 

that’s what I’m thinking too. I’ll put a plug in it and fill it and see if everything operates like normal.

 

 

Wrong.

There is nothing there but an empty hole.
No sensor, no trans cooling bib.

Just an empty, unthreaded hole.
