ok so recently I had some installations done and well the guy had to do some customizing.. well he claims there was no way to get the lines into the oil cooler or something so he just has a direct line instead of going through the cooler which he claims is perfectly fine and safe.. well i am doing some minor mods with the sway bars and whatnot and i look under the hood and see my coolant is completely gone out of the car however about 2 days earlier it was filled to the fill line.. just wondering what is going on with that and what i need to be looking at.. ever since they did what they did my oil gauge reads 50 if that what that line is between 30 and 60.. and then while flooring it it goes to the 60 until i come back down to regular speeds.... thanks
