OH6PILOT Posted October 7, 2017 Author Share Posted October 7, 2017 STEP 5: DRAIN RADIATOR, REMOVE HOSES, REMOVE RADIATOR. Ok, so I decided that the more room I have the better, so I've gone a bit further and yanked the whole front radiator assemblies, to include the coolant bottle and AC Radiator Assy. In order to remove the radiator shroud, you also have to remove the fan... so..In order.. A. DRAIN RADIATOR. There's a small drain plug on the bottom left side of the radiator (if you're using vehicle terms looking from drivers seat, otherwise if FACING the vehicle from the nose, it's on your lower right side. Place a bucket or sufficient catching media under the front frame support and drain the radiator. would love top hear how many people get a clean catch from here. Mine came out rusty brown. (I change antifreeze every 12 months and flush the radiator as well...so) This is where the drain is located on the radiator... Link to comment Share on other sites More sharing options...
OH6PILOT Posted October 7, 2017 Author Share Posted October 7, 2017 STEP 6: Drain the Engine Oil. While you're at it, remove the Oil Filter. Drain it too...and throw it in the trash. A.) Remove the oil drain plug from the bottom of the oil pan. It should be a 12mm or a 14mm if it's a standard plug (Bolt). ______________________________________________________________________ B.) Use a rag and grab the oil filter, turn counter clockwise...yes...to the left. Oil will drain from it, so have a catch rag handy. Link to comment Share on other sites More sharing options...
OH6PILOT Posted October 7, 2017 Author Share Posted October 7, 2017 (edited) STEP 7: Remove Fan Shroud and Fan Assembly A. REMOVE UPPER RADIATOR HOSE. Very simple, it's either a normal hose clamp (Flat tip screwdriver), or a NISSAN hose clamp, which will be either 8mm or 10mm, depending on the size of the clamp (Mine has both, as pictured). Remove clamps, then remove hose and inspect for cracks, wear and deformities. Set aside if hose is still serviceable. _________________________________________________________________________ B. FAN REMOVAL...very simple...4 10MM nuts secure it to the water pump pulley. close quarters getting in there, but it comes apart easy enough. _________________________________________________________________________ C. SHROUD REMOVAL...Depending on if your shroud has been removed a number of times or never, it will have either 4 mount bolts (all 10 MM) or two (like mine). They are located at the top (one either side) and one on each side mounting it against the radiator frame. Remove the four bolts, secure the fan, and lift the shroud and fan out together. Inspect shroud fro cracks, deformities and set aside. __________________________________________________________________________ C. FAN CLUTCH INSPECTION... visually inspect fan assembly for broken blades, deformities, general condition and mounting security. Clutch assembly should move by hand, and should have a slight amount of smooth drag to it (similar to moving through warm molasses). If it turns without any force at all, or doesn't turn, the clutch is bad. Replace it (around $45 at Autozone) ___________________________________________________________________________ Edited October 7, 2017 by OH6PILOT Link to comment Share on other sites More sharing options...
OH6PILOT Posted October 7, 2017 Author Share Posted October 7, 2017 8. Remove Lower Radiator Hose A. Also very simple, it's either a normal hose clamp (Flat tip screwdriver), or a NISSAN hose clamp, which will be either 8mm or 10mm, depending on the size of the clamp . Remove clamps, then remove hose and inspect for cracks, wear and deformities. Set aside if hose is still serviceable. Note that the condition of the hose and the plenums will indicate the condition of your cooling system...Mine is clearly horrible. Link to comment Share on other sites More sharing options...
OH6PILOT Posted October 7, 2017 Author Share Posted October 7, 2017 STEP 9: Disconnect Transmission Oil Cooler Lines A. Both of the lines are located at the bottom of the radiator. They are either a normal hose clamp (Flat tip screwdriver), or a NISSAN hose clamp, which will be 8mm, depending on the size of the clamp . Remove clamps, then remove hose and inspect for cracks, wear and deformities. _______________________________________________________________________________ B.Bear in mind that these will drain transmission fluid all over the place, so make sure that you have a catch bucket setup below the radiator, or make sure that you have a few plastic bags readily available to place over the ends and zip tie. _______________________________________________________________________________ Link to comment Share on other sites More sharing options...
OH6PILOT Posted October 7, 2017 Author Share Posted October 7, 2017 STEP 10. Remove Radiator A. Remove the bolts that attach the radiator to the body frame. They should be standard 10mm Bolts with large washers. ________________________________________________________________________________________ B. Lift out the radiator. With the radiator removed, inspect it for leaks and damage. I would recommend flushing it with a garden hose. Cover the outlets and fill wioth water and alternately open an outlet to let water flow in different directions. You can also fill it full of CLR to get rid of a good amount of the rust and lime that accumulates. MAKE SURE to put it in a place where you wont accidentally stick something into the vanes. I recommend placing cardboard over the front and back vanes. Link to comment Share on other sites More sharing options...
OH6PILOT Posted October 7, 2017 Author Share Posted October 7, 2017 (edited) STEP 11A. Disconnect Front Engine Wire Harness This is the fun part, especially if you aren't familiar with the Pathfinder wiring system. A. Disconnect all wires running between the engine and components attached to the body. NOTE!!! Before disconnecting or removing wires, mark them with pieces of tape or take pictures of them to identify their installed locations. This will eliminate potential issues during reinstallation. The primary connector bundle is located on the right valve cover. _____________________________________________________________________ B. Disconnect the bracket from the valve cover (Two 10mm bolts) _____________________________________________________________________ The following is a guide of the remaining connectors to remove, along with their connector ID numbers and what they go to.

The Engine Guage temperature switch is the single blade connector located directly in front of the Engine Coolant Temp Sensor. (Single wire connector).

Same fuel flow, but easier connectors) Oil Filter Mount (Front beside lower pulley, instead of right aft side of motor) Modifications: Entire Upper Engine Wire harness disassembled, cleaned, tested, and re-wired for new injectors Lower Pulley and balancer bored out for VG33E Crank Lower Timing Cover modified to fit VG30E Balancer (This is a story in itself) Oil Pickup tube in crankcase...completely rerouted and fabricated a new line. (Long Story #2) Alternator Brackets (also requires new longer belt) New to motor: Headers Cold Air Intake Assembly (All Newly Fabricated) All Hoses and lines to motor replaced with new New 4gua wire from Alternator to Battery New 4 Gua wire for starter and ground Assorted new @!*% that is being fixed, replaced or installed since everything is torn apart anyway: 3" Lift Kit with springs and UCA's NEW Bushings in LCA Rebuilt Brake Calipers New Brakes All new Bushings in front Suspension NEW LCA's. (Already on hand...why not) Manual Front Lockers D21 E-Brake Wider Center Console with Cup Holders and different Arm Rest NEW Front Offroad Bumper to accomodate the 9,000lb winch the WIFE GAVE ME FOR XMAS!!!
