Nice video man! I'll have to replace mine before it goes out.

[@TrailRunnerGuy]

Thanks! Yes, I was probably playing with fire driving with it as long as I did!

[@gr1f1th]

just replaced mine this weekend, plastic broke in the same place. I got the hose section replaced too because I was there.

[@TrailRunnerGuy]

Good call. Can’t believe how brittle those things are! Easy fix to avoid a catastrophe!

[@devinbarry1136]

Another masterpiece!

[@TrailRunnerGuy]

Ha! Not so sure about that, but thanks, Devin! 🤣

Mine broke to. Then i crushed the core inlet. So i had to replace the heater core. Such a pain but i love my xterra.

[@TrailRunnerGuy]

Bummer! Not gonna lie - I was a tad nervous taking it off and really hoping I didn’t cause 10x more work by damaging it.

[@Abdultomat753]

Did you ever had an issue about the vdc and slip off light on the xterra . Nice vid btw.

[@TrailRunnerGuy]

Thanks. No slip / VDC light issues for me so far.

[@Abdultomat753]

@@TrailRunnerGuy thanks you 👍👍👍👍

[@thecount1001]

what's your thoughts on skipping that replacement coupler altogether and just connecting the hose directly to the core outlet fitting? problematic?

[@TrailRunnerGuy]

I know people have done it. Heard of a roadside fix doing that a time or two as well. If it doesn’t leak and doesn’t pull the hose too much I don’t see why it wouldn’t work long term too.

[@unclefreddieDied]

So you don't need that bleeder nipple thing?

[@TrailRunnerGuy]

Never used it in 3 or 4 air bleeds (new radiator, timing stuff replacement, etc.). Was always afraid to touch it. Good thing I never did. 😄 Just always burped it, revved the engine a few times, squeezed the big hoses, etc. and never had an issue.

This help me, thank you

[@TrailRunnerGuy]

Glad it was helpful!

[@daniellore2961]

Low oil pressure is oil channel gaskets broken. They are behind the timing chain. My condolences to you.

[@TrailRunnerGuy]

All 2005 Xterras and early 2006s have a live oil pressure gauge (instead of a dummy gauge which just sits in the middle). What you’re seeing here is 100% normal. All timing components including channel gaskets were replaced by me a couple years ago - should outlast the vehicle. 🤞🏻

[@daniellore2961]

@@TrailRunnerGuy ok, thats great to hear. Unfortunately my oil channel gaskets did not get changed when the timing chain was changed. I assumed that was the case for you. My apologies.

[@TrailRunnerGuy]

@@daniellore2961 all good! Sorry to hear that. Opening that thing back up is a total pain (I’ve opened it twice…try #1 was one tooth off. Major oops! 🤣)

[@daniellore2961]

@@TrailRunnerGuy yea, its going to be a pain. I'm considering swapping in an ls v8. As good of an engine as the 4.0 is it is a mess to work on. I wouls rather have old school in the nissan package. I'm still thinking on it though. It will be a challenge.

[@daniellore2961]

@@TrailRunnerGuy I just realized that the ls has an oil channel gasket behind the cam retiner plate. Can't get away from it.
