90 turbo cooling fan..help

alright i just got my car back drom being tuned and was wondering since my fan isnt working and now throwing a CEL code. could i just hardwire the fan to a switch from inside the car and run it when i need to?

well you could.

or you could fix it the right way. :shrug:

well i ended up running off a switch in the car and the CEL went away but the oil light keeps flashing dim red and the people told me my oil pressure sending unit is going bad. i bought a new one and was wonsdering if it is very hard to install?? thanks

nope replacing the sender unit is easy. it’s located on the back of the block. right where everyone taps into the block for the oil press. gauge

would it be worth it buying an oil pressure gauge? and i have the haynes manual but the picture they have in there doesnt do much justice. So where exactly is the sending unit?
