So I was driving back from work last night and well I had too much fun. Smoke started pouring out of the hood, I got a low coolant level warning light, thinking the engine was overheating I turned on the heater full blast only to get hit with cold chilling air and the smell of coolant. I really hope I am clear of a blown head gasket assumption since the exhaust wasn't shooting out white smoke. I am guessing it's a coolant hose that burst somewhere, I opened the hood this morning and the reservoir was completely empty, seeing that I pulled out my trusty trunk coolant and filled it back to top only to watch it all flow out of the car and on to the ground. Can anybody make an educated guess based off my amateur observations? I am looking into metal pipe replacements to change out the plastic ones and while I have the supercharger off I will change the plastic coupler isolator in the supercharger. Things to note, the smoke blowing out of the engine bay seems to be coming from the back of the engine.

I found some metal replacements and stronger plastics for the coupler but I would love to see the ones you guys purchased!

have you seen my videos ive installed on menbers cars XJs F-types XJs and they all been on them for a coule years now with no issues

 

Find and repair the coolant leak, then use a tester to check for exhaust gasses in the coolant. If the blue solution turns to a greenish yellow, there is combustion gas in the cooling system from failed head gasket(s).

 

Failed head gasket on AJ126 bank 2, cylinder 6

 

That smoke coming from the heads looks sad. I had once a red sign on the dashboard "engine overheating" due to a clogged radiator, but the system was not leaking. Luckily the head gaskets were fine. I would do as NBCat wrote

 

Most likely it's the plastic crossover pipes blown. If you stopped quickly most likely the heads didn't warp. The test of coolant for exhaust gas will work, but if it drained out, it might not show. I would get new aluminum replacements for rear and front coolant pipes plus the oil cooler connector. Pulling supercharger is not extremely difficult but it may be stuck if never removed before. Depending on mileage I might would change the oil as it is hard to get at. Also think about removing symposer with a plug. One other thing to consider is the 1/4" coolant hose from back that goes under supercharger to the throttle body and to reservoir. I rerouted around the left side of engine and reconnected bypassing the throttle body. I am I a temperate climate so that's your choice. The band was allowing a weep so I passed it. BE CAREFUL with those quick connects as they have a short insert that will snap if wiggled. Must pull straight out and even then they break. New tubes/Hose at that point.

 

Note that there have been a few quality issues reported on the F-type forum with the EuroAmp aluminum pipes, though most are happy.
