Ls1 Cooling System Removal Youtube Yes gen 3 4 engines are nont reverse cooled. coolant goes to teh block 1st, then the heads. the gen 2 lt1 (iron and alum head), 1996 97 lt4 and 94 96 4.3 v8 vee eight rpo l99 are all reverse flow cooled. heads get coolant 1st, then the block. i'm pretty sure the newer gen 5 lt1 is still conventionally cooled. Step 3 – remove the upper radiator panel. disconnect the air intake temp (ait) sensor and mass airflow (maf) connections. loosen the worm clamp where the intake connects to the throttle body and disconnect. remove the four 10mm bolts from the upper radiator panel. remove the panel and air intake ducting.
Vz Ls1 Automatic Radiator Removal Just Commodores You might need about 2 1 2 gallons of 50 50 mix. keep an eye on the small coolant crossover pipe. when you see coolant coming out of it stop, reconnect the hose and clamp. this step helps to eliminate the majority of the air by the crossover pipe. the pipe is the highest point of the engine cooling system. recheck the coolant level on the radiator. Take the clamps off both of them. with the radiator cap off, expansion tank whatever, begin to pour coolant through one side slowly and carefully avoiding spilling until it begins to pour out of the other side. hook them back up the way you unplugged it and let her rip! it's that easy and pain free. 05 ibm blue a4. From the cylinder heads, the coolant is then forced to the thermostat. the flow of coolant will either be stopped at the thermostat until the engine is warmed, or it will flow through the thermostat and into the radiator where it is cooled and the coolant cycle is completed. 11 18 2009, 10:18 am #7. redphoenix1998. The introduction of the zinc anode protects the cooling system from galvanic action as electrolysis eats away at the zinc rather than the aluminum. coolant: there has been much discussion about which coolant is best for ls engines, particularly in engine swaps. dex cool is the factory engine coolant and is recommended by general motors.

Steveo. 5008 posts · joined 2008. #9 · jun 28, 2014. screw all that, just jack the front of the car way up in the air and pour coolant in, first while not running, then while running, done. the bleeder screws are useless as long as you can get the upper rad hose way above the top of the engine.
