If you use a silicone sealer make sure on the tube or the package it SAYS "sensor safe". If you are not using the silicone hoses behind the water pump then you have to get the clamps as tight as you can because you will not be able to get there again to retighten them. You should also, at the same time, replace the bearings in the idler pulleys, the belts, and if the car hasn't had a tune-up in a long time replace the cap, rotor, ignition wires and spark plugs, it's really easy when you do the water pump. Also as long as you are in there you should be replacing the seals on the water distribution pipe and any vacuum hoses that are stiff. Use new copper seals on any fuel lines that you disconnect.
