Removed and installed

Jd,
I also was able to move air filter box instead of coolant hose for fitment …. I started to remove hose clamps at the radiator end… before removing hose I figured it wouldn’t be the best idea. Moved the filter box for extra room and was able to maneuver smog pump in and out. Definitely a tight fit but thankfully didn’t damage anything … A little “tetris” knowledge goes a long way lol. Fit the new pump and adjusted hoses slightly, now installed and connected. Its now throwing P2432 (secondary air injection system Air Flow/Pressure sensor circuit Low Bank 1.

I Asked my mechanic what and why that code was being thrown… I have a bad Amp Probe for battery cable end… which is the reason check engine and battery dash light are illuminated.

Going to be replacing the entire cable assembly and he assures me that once that’s connected I will be free and clear of codes and dash lights.

Cleaner and also gave better access to the hose fittings.

ENGINE SHIELD(same shield when you change the oil filter, no coolant loss):

Hopefully, old blower with new check valve and relay will have enough to pass smog. CEL remains lit, but only pending P0418 and P0411 remain in the codes section. Doing the driving to get the sensors in the ready state.

Lol, thought they meant the radiator shroud. Couldn't get the thing out without just pulling the shield. Kept hitting the shroud.

What's one more duh moment?

Are you still using the crappy azzed OEM Battery Terminal Connectors? Known JUNK, they all fail, should be hacked off and replaced with a quality aftermarket set like Stingers or your favorite brand. LOOK it up. First Mod to do to every H3/H3T,
