Ive got a ton of coolant in the electrical connectors from doin a headswap. What kinda stuff should I use to clean them out????

 

brakeclean

 

Electraclean is the best that I have seen. It is hard to find though. Be careful though, it will take your skin off

 

I wouldn't use brake cleaner on "mystery plastics".

WD-40 will chase moisture out pretty well (that's
its original purpose, WD being "water dispersant").
Just douche them real good.

WD-40 should not be put into the airstream or the
engine oil though. Silicon is bad for O2 sensors.
Silicone spray is no exception.

 

dam i hope i dont have problems. i just reconnect them how they are and forget about it. if i were to worry about it, i would probably blow them out with pressureized air and use electraclean. you can find it in most auto parts stores.
