I’m having same issue.

Hi everyone,

i just read this post from few years back and I see people still respond to it and I’m hoping you guy will help me too.

Car :- 2012 infinity G37

So I have the same issue where my pipe spilt in 2 whee the middle piece was broken. My house was 12 miles away when this happened so To get home I keep putting water i until it leaks and I can drive 3-4 miles after filling. I would watch the heat needle inside the car if it gets to 70% I will stop few few min to let it cool and fill the water again and did this 2-3 times and I was home. I’m not car guy so I asked friend and dad they both thought it was radiator hose since it was dark couldn’t tell so we try figuring it out in day light and I filled the water again after 70% it starts to leak not before but then I saw water leaking underneath and saw 5-7 min car was heated again saw where the smoke was coming from and it was from heater hose as shown in the picture so my help made this metal piece from the pipe that fit exactly in the both hose and we put clamps to tight it back issue solved but I noticed after 10 min warming up needle goes 40% and stays there but the radiator cap which is medal kind when I touch it it’s burning hot 🥵. Is that normal ? I tried turning my dads car and touched it was cold and wasn’t heated much. Since there was leak in there I think there wouldn’t be any coolant so I got 2 1 gallon coolant which I will fill tomorrow and see if that help. Do you guys know what is the cause or maybe any help or tips if you guys want to throw in there before or after I should do?

See tools from above post. The angle one go to hose clamp to engine. Position from passenger side gives best angle. The straight plier go to body hose clamp.

Once clamps can be remove, drain coolant. Do NOT remove hose until coolant is drained. See DIY for coolant drain. Connect all hose & connector to 1 piece be.fore installing. Put hose & clamp on engine first before one going to body.

Fill coolant & bleed. Hope no more leaks or missing coolant. GL

Rule #1, NEVER touch OR open a radiator cap when the engine is HOT. You WILL seriously burn your hand or potentially injure yourself and others. As the engine warms up and the coolant gets hot, the cap will get hot as well. This is normal.

Make sure you add coolant to replace what was lost when the connector broke plus any spillage from the repair.

There is likely air in the system which you will have to make sure is removed from the system (see this DIY thread).

What does the temperature guage in the car read? Radiator caps get hot, so this is not a red flag unless your temperature guage is posting an abnormal reading. With these cars, if you eliminate leaks and take the time to remove all air with a "Spill Free" funnel, then the coolant systems are fairly bulletproof.
