Thank you so much. I just did this and so far so good. I appreciate what you do.

[@TheEnthusiastMechanic]

Thank you I’m glad I could help

[@rosemarieannatherien3156]

Very intuitive. Thank you

[@kurttaylor5870]

Thank you!

Great vid man. I was a little confused by a video by the CarCareNut who said to turn OFF the rear heater system... but that seemed weird to me. Granted that was for a Toyota Highlander (which is what I drive) so I'm not sure what the difference is between his method and yours. I'm inclined to go with your method as I used sealant additive last year to try and hold off the leaky radiator replacement project.

You always wanna have your front and rear heater in heat mode because you wanna be able to circulate the coolant through those systems to get all of the air out. I’m not sure what the car care nut was referencing, but it doesn’t really matter on any type of car if coolant flows through it whether it’s summer or winter you have to have the vehicle in heat mode on both front and rear. Otherwise what will wind up happening is you can get trapped air in there and the first time you open up your heater you introduce the air in the system and wind up having an overheat.

@@TheEnthusiastMechanic OK this confirms what I was thinking. Thanks man, great stuff!

[@patcurry6246]

Very professional thank you

[@TheEnthusiastMechanic]

You are very welcome, Thanks for watching!

[@mando0503]

Does this vehicle use two heater cores one for the front and one for the rear or is it the same one?

[@TheEnthusiastMechanic]

If you have a separate rear heater there’s 2 otherwise there’s at least one in the front.

Does overflow need to be emptied before this

[@TheEnthusiastMechanic]

It can be full or empty doesn’t matter

Fans never kicked on what to do

[@TheEnthusiastMechanic]

Sometimes it can take a while for the fans to kick on. There’s been instances where I’ve waited 45 minutes. You always just gotta make sure your gauge isn’t going into the overheat and of the fans don’t kick on and your gauges showing overheat that means you gotta figure out what’s going on with the fans

[@yjenkins4564]

How can the fan be on 1 but you said keep the heater and AC off. Also, if you don’t have that yellow thing, can you do it old school in an emergency? Thanks so much! Video is very informative

[@InexplicableBill]

@@yjenkins4564 So there's a couple things happening in your question. Firstly, if you simply turn the HVAC power OFF, this will often close a valve in the car which prevents the coolant from circulating through the HVAC system. That's not good as there could be trapped air in that part of the coolant loop. Most modern cars have an AC button to turn on the AC compressor in any mode, but they will also run the AC compressor automatically when you chose certain modes like Defrost (to dehumidify the air). If your vehicle doesn't have an AC button, consult your owner's manual to learn which modes automatically trigger the AC compressor so you can chose another setting that won't. *For those who don't know - running the AC compressor also instantly turns on the radiator fans, which he's trying to avoid for this exercise.
