I have a 1988 Monte Carlo that currently has a 5.3 LS and 6l80e in it. A friend and I have been working on it since May and we’ve hit several problems. The engine is in now and the only issues remaining are wiring. Has anyone here had experience with cold case radiators? I’m running that with a Holley terminator X max and a Holley electric fuel pump. I’ve had to buy 4 different adapters for the terminator and the wiring harness for the radiator doesn’t fit. Specifically the temperature sensor does not fit in the radiator port.
Part number for the radiator is GMG544-5K and the fan wiring kit’s part number is 359-EF-1
