Over heating and no hot air inside????

[gs300cky]

The dealer recently screwed me over needless to say. They supposedly replaced the head gaskets, t-belt, coolant, and water pump. Plus an oil change (which they over filled the oil)
Well I had to tow the car as I just moved and I went to take my car out for the 2nd time as ive been fixing a o2 sensor cel. Well now i fixed it today but noticed my car over heated which is when I saw my fans weren't plugged in, but even after plugging em in it still overheats and I don't have heat inside.
What do I check or start with? I saw 3 plugs under the driver dash unplugged. Would any of these be tied into the heater core ya think?

Is there enough coolant in the system? How's the overflow tank? Are the upper and lower radiator hoses hot/warm?

[gs300cky]

Seems like the rad looks low but there's more then enough in the overflow..? As for the Jose I touched the upper one and it was only warm I couldn't reach the bottom. Could this all be caused by unhooking my battery and maybe causing the ecu to forget the tune? Or is that just crazy and completely impossible

No heat most often means the heater core is empty. You need to bleed it properly

THIS

Add coolant, bleed system til you get no more bubble, drive around then double check it. If you still have an issue then its more than just coolant.

sounds to me they definitely didnt do the job correctly, as they forgot to plug the fans in and it seems put enough friggen coolant in the darn thing or even bleed it at all.

now that you say it overheated did the temp needle reach all the way up to H? if so..i would be calling that dealer for a new motor as when an engine generally overheats like that it MAY/CAN (and i would lean more to will on this one as it would be my car that just got worked on after i paid all this money) cause engine damage. engines dont like getting overheated...unless its a 4.0 jeep motor, haha. but seriously...all jokes aside...they just did all that work and it overheats? they would DEFINITELY be getting a nasty upset call from me and i would want it either redone (because at this point if they forgot to simply plug the fans in, what else did they forget to do correctly?) a new motor, or my money back. thats bull****.

Since it overheated (shut the car off as it hit the red line) Would that cause the heater core to get bubbles? The coolant was bubbling so I figure it would have got a couple huge bubbles in the Heater core

Not necessarily the cause. Sounds like the system was not properly purged.

You have an air bubble in your system.

I agree - probably an air bubble in the system - when the car is cold, fill the radiator all the way up, then close the cap and open the cap on the tank by the intercooler, then fill that one up - turn on the car, and let it warm up (until the cooling fans come on) - keep the upper tank topped off as air works its way through the system (squeeze the upper radiator hose a few times to help push bubbles out) - that should take care of it.

for the plugs under the dash, which ones are they? there should be a few (diagnostic connectors) which are always unplugged unless you are flashing the ECU with an accessport or something like that.

[gs300cky]

Thanks for the help^^^^ and the plugs are a yellow one and a grey one both on the driver side. The yellow one is all the way to the left located by two green ones
The grey one is screwed down to the knee panel it's under the obd2 plug. I will post up better pics of them.

As for an update on the situation, I think the car overheated due to the fans on the radiator not being plugged in and kicking on when the car warmed up, and when it lost all the coolant that's why I probably lost heat inside the car. Needless to say today I steam cleaned the whole engine bay and topped off the fluid while the car was cold. Then I warmed it up which took about 15min and I had heat again. I left the cap off the rad so maybe that's why it took a long time to warm up, anyway i drove it around the block with no over heating signs the temp gauge reads just less then halfway.I'm gonna warm it up tomorrow morning then take it out on a test drive & hopefully everything is good again.

So can anyone tell me if unplugging the battery + - will erase my tune?
Also any help on the connectors under the dash please?

I was gonna say check your thermostat as well, I've seen that happen a lot with plenty of vehicles

[gs300cky]

Turns out it overheated cuz of the fans, which when that happened it caused me to loose all my coolant. So I plugged in the fans then filled the Coolant and BAM I got heat and no overheating of the engine. So it's all back to normal!!! Minus my boost gauge doesn't read properly now but that just means upgrade time
