Coolant Leak 1999 5.7
Hello guys, For some time I've noticed a very slight loss of coolant. Today I decided to take a closer look and I noticed a drop of coolant on the starter motor. I took a closer look with a mirror and I suspect a little leak between the cylinder head and the block right above the starter motor...- Modoyadney

5.7l Vortec Distributor Timing
I just installed a new Bravex Distributor in my 97 Yukon GT 5.7l Vortec after doing the MPFI upgrade. I fiddled around long enough so the distributor body sat somewhat parallel to the intake, and there was no more P1345 code. I got an OBDLink MX Bluetooth scanner with Dash Command App installed...- YukonGTmaster
