Radiator blew now showing P0117 code

Thanks for the help, just to follow-up:

Originally, the radiator blew and spilled off some of the fluid. After getting the car home, I drained out whatever fluid remained in the radiator and replaced the radiator with a new one. There was some cleaning to be done around where the fluid spattered.

After installing the new radiator, I followed the basic refill procedures, I warmed the car up and started adding coolant to the reservoir but it would not drain down. (I showed no other fluid leaks but noted that the reservoir coolant I added just kept to the level I had added.)

I'm familiar with how head gasket work and I do not see any smoke, liquids, etc. Coming from them or the floor, absolutely nothing. What I'm noting is something like a clogged drain where nothing seems to be flowing through it.

I let the car run for a while and then it began to shake and rattle in the front end. I immediately turned it off. The following day, after the cool off, the car started up as normal, just as it did the day before. However, before starting the car, I checked inside the radiator and it was completely dry, no fluid, nothing at all. I can only deduce that the pump may be bad or a sensor is forcing the fluid or to send the wrong signal. If the thermostat was bad, I would assume, from my understanding of it, that some fluid would have gotten through during the cycle, and if damaged would have produced some smoke, but did not see any smoke coming from the area.

I see. I'll give the car a thorough look in the morning and check for white smoke, etc. I presume it will have to run for a few minutes before any smoke comes out. I will also check the head gasket again, much closer this time. If necessary, I will remove it and look inside too. Thanks.

Thank you. Just started looking for leaks again and did note drips from under the car near the rear of the engine. Have been wondering what would be the best way to confirm the source, will try this.

After some of your advice, I decided to run the engine for a while. I watched the heating gauge and noted that it wen passed the 40% mark. When it went passed then 50% mark, I turned off the car. I looked under the car and found that it was leaking fluid from behind the engine.

I tried to look behind the engine with a scope to see if the engine or valve was, fruitless. I decided to tear down the intake area. Unfortunately, that will take a few days since I have other issues to handle.

Question: the car does run for a short time, would an engine issue (something outside a bad gasket) allow it? I did not spot any white smoke during the heat up, just undercarriage fluid.

I am focusing on taking apart the cabling, hoses, etc, to access the intake. In no hurry since I'm pretty busy with other things. I will let you know my progress. Thanks again.
