Nissan Frontier: No Heat 🥶

In this video I help out a customer with a concern of no heat in his Nissan Frontier with the big 4.0 Turns out there was more to the issue than just a bad thermostat or plugged heater core.

One of the many things that I sincerely appreciate about this channel is the willingness to show the oversights that routinely occur with ALL of us.

I recently learned something about 'no heat' that surprised me. My 22 year old Camry seemed to need to have the heater cored flushed every few months to get better heat. The surprise was when I found, that in spite of both radiator hoses looking good on the outside, one of them was degraded so badly on the inside it was constantly shedding small rubber particles.

[@robertjoseph1592]

@Duane K When you live out here in Arizona, a good mechanic will recommend changing hoses and belts every 5 years. The 150 degrees experienced in the engine compartment during the summer just destroys them that quickly.

As a kid, I watched my father install the Prestone flush kit on his 1954 Plymouth Savoy Flathead 6. Tee fitting permeant on heater inlet hose you connected a garden hose to. A 90 degree plastic diverter went into the radiator fill. A drain, flush and coolant replacement took all of 10 minutes and dad did it every fall. And yes, the coolant was dumped in the road back then.

[@michaeldepetris696]

I have a 2014 Frontier. They are notorious for air pockets in the the coolant system. The air pocket migrates to the heater core and thus no heat unless going up a hill. Park on a good hill, take cap off and let idle. It will force the air out and problem solved. Using a vacuum fill also fixes it. They are also very touchy with aftermarket thermostats. I did, made the truck run hot. Put in a Nissan thermostat and runs perfect now.

[@chrismechanic2000]

my wife had a corsa years ago, every winter she complained about the heating not being hot, i had to jet blast out the heater matrix every year, rust and junk used to collect and start to fill it up, we only had that car 3 years, the heater was just 1 complaint of many, i sold it and bought her a bmw compact, never had to touch the heating system in 5 years.

This brought back nightmares of trying to change the thermostat on my old Frontier. The good part was the thermostat housing was right up top in front of the engine. The bad part was that the housing had three bolts that were NOT the same. I didn't know this and it was pitch black and freezing cold by the time I began putting it together and I could not get that damn housing to go back on. It took many freezing hours reconsidering where my life had gone so horribly wrong before I figured out what was wrong. Amazing how quickly things go back together when you put the right bolt in the right place. It all worked out in the end. That truck taught me a lot. Learned how to do a total radiator replacement, a skill which came in handy when my next vehicle got a cracked radiator. I did that swap in the daylight.

[@SteelheadTed]

I had a 2004 with thermostat on top. My mistake was taking out the hose that goes to back of engine when I didn’t need to. It was a mother lover to get back in. Good times.

I had a leak in the water pump of my Miata. It would only leak under pressure and the leak was small enough it would evaporate almost immediately. The only clue to coolant loss was I had to add about 1/2 gallon of coolant each year. Eventually I did a pressure test and saw the coolant leaking from behind the harmonic balancer. I replaced the pump and life has been good since, but like Eric I couldn't see a leak or smell one.

Just ran the water hose into one of the threaded connections, air into another one, and the 3rd hooked to a hose going to the heater core. I ALSO used your trick to get a small water pump, and some CLR in a bucket, and forward flush plus back flush the heater core with that stuff, for an hour each way.. My 98 S10 had not had heat in 3 years. That process did the trick! A WHOLE lots easier than ripping the entire dash out to replace that core. Thank you for that inspiration.

I don't know why you are beating yourself up about a hose that was deep inside and not visible. Even the weep hole would have been hard to see without getting into the repair.

Or the ONLY two other ways is do something completely different, or not bother. That's the ONLY way I can think of. Is 50:50 the same as half and half? And uh, does it depend on density or volume of said liquids? Astro-physics and engineering were wasted on me. I think we have both learnt something from justlooking2222 though. Important, don't forget, it's a ODD number of eggs - never use an even number as that will block your MAF big time on a Datsun.

@@stevekelly5166 I like to use Duck eggs in my cooling system mixture. The antifreeze beads up and keeps it’s strength. Not a quack theory.

Thanks, another great Frontier video. My mechanic replaced my radiator before it failed on my 2010 Frontier. Failure avoided was mixing coolant and auto trans fluid. Thanks like your videos.

Good catch. Sometime it’s better to be lucky.

[@tomtheplummer7322]

Lucky or good. I if you’re good you tend to have better luck. 😉👌🏻👍🏻

I love that you use so many salvage yard parts to replace everything from subframes to vehicle computers (ok not in this video so much) but I was horrified when you reused that nasty mushy old heater hose and left the dirty filter in. 😱 Everyone is a critic. But I love your videos Eric! 😬

I miss my old 350 small block with the thermostat right up front top and center. Engineers seem to be having a contest on who can make them the least accessible these days.

Tell me about it. I own a 2002 Envoy with the 4.2L. Last replacement cost me hundred$. And I supplied the part.

[@2aminitials]

You can replace the thermostat in the video without removing the cooling fan / shroud. You do have to move the air intake tube.

"Stink pot" Ha...my mother used to say that, usually referring to me. I don't know if I ever heard anyone else use that phrase. Thanks for the memory!

[@williamalbright8878]

Awesome job sir appreciate you taking time to film

[@dajoway]

Eric you are very perceived on the work that you do ! Thanks for sharing your videos for use to view! Keep up the great work, David Upham

[@wyattoneable]

You would have found that clamp sooner or later, I have faith. I hope you and the family have a healthy and happy New Year.

I had one of those cheap Nissan hose clamps break on the heater hose in my 350z. The heater hose was spraying a fine mist of coolant when I brought the engine up to temperature. The thermostat on the Murano is almost identical with three bolts but is a little harder to install since it is in tight quarters.

Another great video from SMA .hope you had a great Christmas Eric and family.truly looking forward to the new year with SMA
