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.

You're just the damned best.

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.

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.

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 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.

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.

Awesome procedure. I made one of those blaster hose thingies out of a 3-way hose connector from Lowes, as Amazon didn't have one of those last summer when I needed it. Worked perfectly. 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.

After initially blowing/flowing through the heater core when flushing, might want to go check the passenger floorboards to see if you're leaking inside the vehicle. Fully realize you may not have been before, but that possibility may exist now since the pressure and flow for flushing is greater, plus the scale you are freeing up may have been the only thing sealing the core from leaking. Of course, flushing that radiator might have been easier and more effective with upper and lower hoses removed. That way, any rust and scale in the bottom of the radiator is flushed out and not recirculated. Did that with daughter's truck and got a significant amount of crap out of an older radiator - and of course, daughter never did anything in the way of maintaining cooling system.

I was thinking this would have been a good case for the thermal camera. You could see if the heater hoses were actually getting hot (ie, coolant get there) and if they are similar temp to everything else or weaker. That would be a good indicator of poor flow / low levels. If they were all equally hot, then you could be more on the heater unit itself. But good catch on the actual problem, nice!

Thermal cameras are like cheating. I use them to spot faults on printed circuit boards all the time. Makes it too easy.

You are a very good mechanic. It shows that you like your work. Thanks.

[@mrcogginsgarage7062]

Good to see you Eric hope you all had a happy Christmas and that you've not been hampered too badly by the atrocities that the weather is dishing up Stay well safe and warm.

Never hurts to pressure test VS a visual inspection, the fact that you mentioned it only worked uphill gave me a hint to LOW coolant

[@williamalbright8878]

Awesome job sir appreciate you taking time to film

[@ChrisPadillaAZ]

Eric, you’re so awesome. I could never work there, I’d be attacking every bit of rust I see. Or at least cover them with paint. You’re the man!

[@josecondemarin9586]

Hello Eric Merry Christmas and a happy new year, love the clear explanation, What an awesome video !! Take care thanks 😊

[@chrismoore6293]

Eric, great job on the ol’ Frontier. I spent many years with Nissan and found that these cooling systems do not like to function correctly if the coolant is below the MAX mark. The service info was incorrect for years and the reservoir is also improperly marked. Top her off about 1” above MAX and bleed the air out of it and most cooling system issues that I’ve ever had with the 4.0L drivetrain were resolved…barring any leaks or other mechanical failures, of course. Thanks for all of the great content that you post. You and Ivan are two big reasons why I stepped away from a management position and went back into the repair side.

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.

[@MrOnemanop]

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.

"Nobody's gonna trust me anymore" Mate I would trust you with my car any day of the week. Hope your Christmas was great and you have a happy and successful New Year......from you hordes of fans in Australia.

[@watajob]

Indeed. No flames and no blood. Not much of a "mistake" at all.

[@mingthemerciless6855]
