Loosing coolant

[tree98]

First things first, you need to copy the program out of the ecm and send it to Rawze so he can tell you if it's harmful to the engine( I'll bet you it's bad!!) Also you need to get a pressure tester and pressurize the cooling system to 20 psi and then you'll be able to easily find any external coolant leaks you may have. If you don’t find much external, then it's time to drop the oil pan down and have a look up at the cylinder's from underneath to see if you have an internal leak ie. Dropped liner, bad injector cup.
