Very educational video, thank you, I have the Same problem with my 2018 g80 3.8, dealer replaced the thermostat twice and the water pump, now they wanted to replace the thermostat again for the 3rd time In under a year, because the heat only works, when the the fan speed is at low, once I turn the fan speed to high, it’s cold, the radiator lower hose gets hot if the heat is off, once the heat on it stay cold,
I got the code and I ordered for the thermostat complete with the housing just need to find a mech to fix it for me I went to Genesis the labour was too high that I was charged for 2018 genesis 3.3T
This looks to be the 3.3T engine. Interesting, for such a fairly new car, already needs a thermostat replacement. I guess it's true what they say, turbocharged engines require more maintenance and more frequent repairs compared to NA engines. I have the 5.0 version for this car, and I am still on the original thermostat. Soon going to have the dealer replace it as I am approaching 100,000 miles.
P0599 3.3T 2018, Replaced thermostat housing, and water pump, no heat, can’t bleed air? Used the funnel, car runs up to 230 degrees 210 degrees too, and the heat doesn’t blow warm, heater core hoses cold, as if thermostat isn’t opening….bled a lot of air out, still nothing. Took 2 gal of coolant.
Usually what i do is used scantool to activate the electric thermostat under the software management, and then i manually bleed the cooling system. This engines are hard to bleed. You can try to elecate the front end while doing the funnel bleeding, then heater on and then raise the rpm. Just watch the funnel coz sometimes it will overflow back to the funnel and it will create a lot of mess of coolant. Hope that helps.
If I don't have the scan tool to electrically bleed the coolant what are my options? Is this mandatory to do with the scan tool or is there another alternative?
You can try just the traditional bleeding, put a funnel on the raditor neck then watch for bubbles, then when warm up turn on heat then rev the engine to help move the coolant. You can also do vacuum fill.
Hi, I have the same code and pretty much followed you here. I tested the plug to the thermostat and found power and continuity to the PCM side. I reconnected the plug and tested resistance on the thermostat and there was none. I then warmed up the car and there was still no resistance. Does that mean the thermostat is dead? Wouldn't it behave differently when fully warmed up?
If the circuit inside the thermostat is really open you wont get anything. That needs a new thermostat assembly. What i found on those failure the sensor has too much corrossion inside.
@@hyundaitech thank you so much for responding. I've ordered the new thermostat and will replace it. Your videos have been very helpful and I appreciate you having taken the time to post them.
Hello, I have this same car, and both fog lights don't come on, it shows it's on on the cluster, but the lights are not on, I checked to make sure that the fog light are connected, is there a fuse I can check? I don't seem to see any fuse for fog lights.
Just happen recently? Could be just a bulb issue in your case looks like its an led one. I dont think theres a specific fuse for the fog lamp. The best thing hook up a test light if it lights up you have led or bupb issue if doesnt light up you dont have power. Hope that helps
Hi I have 2017 genesis g90 with same code I ordered the thermostat assembly it did not come with any gaskets I noticed you didn't have any gaskets either do they not need any?
If its non turbo should be straight forward depends on your experience, if its a turbo one i think if im not mistaken theres some lines need to be remove. Hope that helps
I got the same code I bought the part the thermostat house and brought it to Hyundai dealership have them replace it when I got my car home the engine light pop up and got p0038 code.Do you know what it causes this?
Im guesing when they did the thermostat they unplug one of the oxygen sensor and forgot to plug it back in or something messes the harness. Coz i think the p0038 is curcuit high, meaning open circuit so most likely unplug or damage harness. Double check the oxygen sensor connector
@@hyundaitech Yes, it wasnt plugged all the way in. it was loose.... I also notice my car has been running cool since I got the thermostat replaced and today the code p0128 popped up. Do you think another wire is loose or does it not have enough coolant in the system? Thanks for your help!
@@jashoang5859 could be not enough coolant or was not bleed properly, especially this models so hard to bleed the coolant. I would start from there, check if theres enough coolant and bleed the system then clear the code then test drive.
@@hyundaitech Yh I’ve contacted all them companies and none support the Genesis to scan the systems , to be honest I’m not trying to do anything at the moment and I just like to keep a device I could use in the future

Thanks man, i think they have to bleed the cooling system properly.
Very professional.

Just got the P0597 code today on my 2018 G80 Sport

Thank you sooo much😢❤❤❤
How long did it take for you to replace the thermostat? How about a body shop mechanic who has the schematic but has never replaced this before?
If the person is mechanically incline maybe 2 hours, thats how long usually it takes me 2 to 3 hours with the coolant bleeding.
If I don't have the scan tool to electrically bleed the coolant what are my options? Is this mandatory to do with the scan tool or is there another alternative?

is this same location as the 3.8 g80 thanks? for thermostat
Yes.

I have the same code on the 3.8, hopefully it's not this hard to do, what happens if I ignore this?
Thermostat will not operate properly and you gonna have engine cooling issue.
Hi I have 2017 genesis g90 with same code I ordered the thermostat assembly it did not come with any gaskets I noticed you didn't have any gaskets either do they not need any?
It depends, i think on this case if im not mistaken its just a rubber seal. I will double check
Hi so i just double check our parts catalogue it doesnt show any gasket there. Hope that helps
Thank you so much!
Thus code just came up on my 2018 3.3t any ideas on the cost to fix this?
Should be warranty, if its a turbo set up i think its gonna be more than the NA engine because of the turbo lines
this is 3.3 turbo G80 ... is the thermostat in G80 3.8 litre also an electric thermostat..?
Yes they are electric. But some models doesnt have one im not sure which models
Is it the same part number with the 2018 3.8 G80 thermostat?
I believe they are just the same. Coz last time i ask the parts guy if the part is the same as the other models and he said yes. So yeah.
How long should this removal and replace take?

What tool and software is required for genesis brand diagnostics ?
Hi, i think you can use aftermarket scantool with good features. In my case we are provided with factory scantool. Hope that helps
@@hyundaitech I’ve tried contacting every aftermarket brand but none support the brand , I need it for gv70
@@M.E63 really? Like an autel scantool? Launch? Not the cheap one eh, the one can do system scan?
What are you trying to scan and whats wrong with the vehicle?
