I see the hose they are talking about it's the thin one in the back left (if you are looking toward the windshield). I don't know why they say that hose since it seems there is some kind of electric thing (that says consult on it) right under it and coolant shouldn't touch electrical anything.Rogue Noob wrote:For me, I only got about 1.5 gallons on each flush (The resevoir you keep filling up and emptying count) so I knew about 2 quarts or so was still in the system. I also factored that in when I added the concentrate. About 1 gallon of that, and fill the rest with water and you will wind up around 50/50.
For future coolant flushers.... If you do the vinegar I suggest that only being used for the 1st or 2nd fill, I assume you want 100% of that vinegar out before you refill.
Next point about the hose. Your are correct! Hahaha. I just went to look at the engine compared to the exploded views and have no clue what hose they are talking about. Removing exploded view only points to the throttle body when describing the acuator, how are you going to move that out of the way? I still couldn't find anything that looked like the heater hose. Since that direction is never mentioned in other DIY threads, or the one for the Element I just did, I would just omit that part (I can remove the direction or someone else can photograph the area and we can edit it in but I would just skip that part TBH). My hunch is that step is similar to most of the steps involved in the cabin filter replacement.... useless.
Maybe they are referencing a few of the heather hoses that go straight into the firewall, to the heater core? Anyone else think Nissan does a poor job with their sketches? They seem to leave a lot of important details out. Either way it seems like a minor PITA to locate the hose. If you really want to make sure air isn't in the system leave the funnel on top and have some coolant in it while you start the car. It may burp a bit.
Also, I talked to a Nissan tech and he said that drain screw is impossible to get at and it is the "bleeder screw". He said he never uses it and just props the front of the car up to "burp" the system.
