That's par for the course when it comes to these pumps but you'll be happy for a good long while with the new one from Rob. BTW, did you solder and heat shrink or the new connector on or just crimp and wrap with ET? If you did just crimp it, I would recommend soldering it when you get a chance. It's not going to be life or death but I have seen the car code up due to crimped connections and if it does, you'll see the coolant light come on intermittently so just giving you a heads up about that. Also, you'll be fine spraying down the car. Just use your better judgement about where you're hitting it with the high pressure water and keep it away from the electrical boxes in the upper rear corners of the engine compartment as that is where all the sensitive electronics sit. You can wash them off, just don't hit them up close as you can push water past the seals.

Take care and enjoy the new car.
