my 87 has too many resivours...coolant overflow, washer solvent(front and rear), and there is one on the passenger side right by the firewall. Probably sound stupid but it smells like ps fluid, color similer too, all i know is its kind of low...any help?

 

it is the subzero assist. and you can take it out if you want. it helps the motor start on really cold mornings.(i think)
