Answer:

I am not sure why you would want to get a used water pump from a junk yard as they are not that expensive even for a new one. You should be able to get one from NAPA for less than $40. I would recommend taking off the top part of the fan shroud as it isn't that hard with there only being about 6 10mm bolts holding it in place. Use a scrapper to remove the old gasket from the block. Brake clean will clean the mounting area but will not remove the old gasket material. If you try to install the new pump and gaskets with the old material still in place, there is a good chance it will leak. Check the color of the coolant that is in the vehicle now. If it is green, you can use green coolant. If it is orange (Dex cool), you better replace it with orange or else completely flush the cooling system. If you mix green and orange coolant, it has a bad habit of turning into a mud type material and can cause problems. Other than that, these pumps are not hard to change.
Sounds like your ready to work, it should only take about an hour. Yes take the fan shroud off first (just the top part), you should get a piece of card board and put against the radaitor to keep from damaging it when you take tha fan off. You can use Prestone, Dextrol is just GMs name brand.
sounds like a plan. You probably need to remove the fan shroud, yes. Dont forget to reinstall the lower hose before filling up with coolant
those are VERY complicated engines with counter balancing chafts in them.i would not have faith purely anyone with this activity, because of the fact the valves can bend actually from flawed belt installation. ere is a sequence of SPECAIL save strategies tht may be rented fro the HONDA dealership or aother Honda dedicated automobile fix center. Ther are 2 strategies in touch interior the removing of your balancer that maximum automobile shops won't have. One gadget holds the balancer, and the different removes the bolt. call around approximately this, yet understand that this may be a greater activity than maximum human beings automobile cope with actually, and screwing up can advise extra effective undesirable expenses. additionally that throughout basic terms actual HONDA areas and coolant may be used in there. NO Prestone, and no aftermarket pumps or gaskets!!! solid success!!!
sounds like you know what your doing. but i would advise you to take the shroud off first because it will get in the way. you might want to replace your hoses and thermostat also and use a gasket scraper instead of brake clean. happy wrenching.
