Thanks for the video, Had a similar issue last week, tried boosting the battery but no luck, currently waiting for a reman starter for a swap.
Quick question, Did you change the throttle body gasket and the coolant lines gaskets by the firewall or did you re-use the old gaskets...?
Thanks in advance.

I reused the old ones. It would be a good idea to replace the coolant ones, though, since it's way in there. I took a chance and all still working good.

I’m replacing my starter currently on my 2006 gx, but there’s something attached to my bypass joint that I can’t remove, and I didn’t see that part in your video

Sorry for the late reply but the only thing I can add is that in 2005 they changed the motor to the vvt-i and secondary air injection system. ​@everettethomas193

You need to get that green coolant flushed out and replaced with the red coolant for Asian cars.

[@RGSoCal]

Nah, not really necessary. I've been using green stuff on all my cars for 30 years. Might night last as long, but it's found in every corner of the planet, and it's cheaper.

[@Mark-Dibble]

Yea, pretty necessary. You obviously don’t understand the reason for using the different colored coolants. Match the chemical makeup of the coolant to the metal used in the radiator.
