It is exquisitely clear that propylene glycol is concentrating in the valley under my intake/throttle body. It is evident this is accumulating vis a vis a leak in the same area. I fixed the leak on the water inlet/thermostat housing. My question is this: How much of the top end of the motor must be dismantled to access and replace all the coolant lines attached to or running under the intake et. al.
For a day or so I deluded myself into believing that since pure propylene glycol's latent heat of evaporation at 14.7lbs per sq in. is roughly 360 Fahrenheit that it is simply concentrating there as the water evaporates from the 190 degree Fahrenheit engine. But that isn't it evidenced by air pockets in the throttle body that weren't there yesterday manifesting as poor heating in the cabin of car and green stuff dripping on the ground and having to add 8 ounces of collant after 100 miles of driving...and sporadic steam rising from intake valley. Will someone please tell me I can replace all the lines in five minutes. That would be excellent!
LOL...

Anyway, what is involved please?

I replaced mine after pulling the throttle body. It was a bit awkward, but nothing like working on my Millenia S was...

iirc, there's only one coolant line under the TB, the rest can definitely be replaced without pulling it.

Thank you very much. I presume that one coolant line under the throttle body that you mention is the notorious one that mandates removing everything as if I were replacing the starter?
