SOURCE: how to replace water pump on 1995 dodge dakato 5.2 liter V8
When I do those I find it's easier to get some of the stuff out of the way. Fan shroud, Alternator, AC compressor(don't remove AC hoses just swing it over to the side) and the AC/alternator mount bracket. If you don't have the special hose clamp plyers they are worth buying. (those clamps are difficult with regular plyers) The fan clutch has a special wrench which is thinner. When you start the job break loose the fan clutch before you remove the belt. It keeps tension on the pulley. The nut is normal threading and usually comes loose with a sharp rap of the hammer on the fan clutch wrench.
Here is an illustration of the water pump bolts. I hope this helps you out. let me know how it goes.
SOURCE: radiator fan will not turn on and car overheats.
Check rad fan relay & or fuse under hood in fuse/relay box on drivers side fender area. Map is on underside of cover.

It is located where the lower radiator hose connects to the engine. I just changed one in my girlfriends 2001 4.7L Dakota. She says she has had to have it replaced three other times in the past six years, so it's a good thing your learning where it is now!
Also, if you want to be sure that the thermostat is the problem, just put it in a pot of water on the stove, with a thermometer, and see if it opens when it's supposed to (195 deg. F, for this engine).
SOURCE: 2004 dodge ram 4.7 liter v8 overheating after
I have a 2004 4.7 dodge ram that the coolant gauge goes to 3/4 when towing my bass boat in the afternoons on hot days,I had the water pump replaced because it was wobbling at the pulley,covered under 7/70 power train.Acouple of weeks later towing again had the same problem,the turn on the heater and all is well after 2 to 3 minutes,replaced thermostat and saved and re-used coolant dealer put in and problem still there.At this point I contacted the techs at the dealer and talked with them and we all agreed radiator.Removed the radiator and took to rad shop and had it checked,found radiator plugging up,Now as to why.The antifreeze that chrysler uses is a HOAT type antifreeze,hybrid organic acid technology,with silicates and friction modifiers,this antifreeze CANNOT BE USED WITH TAP WATER OR WELL WATER OF ANY KIND,as it states in the owners manual.Only 1 dealer in this area apparently knows this but this is not the dealer that i took it to.The silicates in this antifreeze when mixed with the wrong water type will seperate and and become heavier and then start to gel and plug the passages in the radiator.This truck only has 46,443 miles on it and mostly used just to tow the boat.Hope this helps everyone else with this problem.Will be contacting Chrysler about this and the improper repairs that are being performed at their dealerships.Lester [email protected].
