engine overheating after wash and long sit

OK, so my car has been parked in the garage for a couple of months now awaiting a new tune and a couple other small things. It recently had its turbo replaced and engine inspected but nothing real major.

I decided to pull it out today and give it a good wash as well as limp it around the block once just to see if anything was leaking (which was one of the initial problems). Well after washing it and hopping in it about halfway around my block the temperature starting shooting up FAST. By the time I was 200 yards or so from my garage it had jumped up to 225-226 and was flashing. I immediately turned it off once I was able to pull in and, after lifting the engine cover, noticed that it smelled like something was burning.

Other things to note is that it is currently about 100 degrees outside and the car was sitting under direct sunlight for the 30 or so minutes it took me to wash it. In addition, I probably got some water in the engine area...I'm not sure if that is a big deal.

Would the car sitting for a long time + being out in the sun potentially cause this? Should I be concerned about the burning smell? Thanks.

By the way...this has NEVER happened. The highest I've ever seen the car was 205 for a split second, and that was in stop an go traffic when it was 105 outside.

Could it sitting in a garage for 6 weeks really cause this? Or is it something that the shop potentially did?

Was the radiator fan running?

Was it driven much after the turbo install?

Sounds like something the shop did.

If you have a water cooled turbo, they may have failed to bleed the coolant properly after replacing it.

Raising this thread from the dead as I'm hoping to solve this issue soon and get the car back on the road.

I'm not real sure if the radiator fan was running. Is there an easy way to check beyond getting out of the car and looking? Honestly, once I saw that the car was overheating I went straight back home and parked the car.

My reflash is set up so that my intercooler fans will continue to run until the car drops below a certain temperature, even after the car is shut off, and they ran for like 30 minutes after the car was turned off.

After talking to the shop, the said they drained some of the coolant out when replacing the turbo, so it seems like an air pocket forming in the lines is what is most likely. I tried topping off the reservoir (as it was a bit low) after the engine cooled down, but do you think that any air pockets are still going to be in there?

I'm not real sure what a watter wetter is, so I'm leaning towards no? haha
