I’m attempting to replace the radiator on a 2007 GS 350 car. Does anyone know how the transmission fluid lines that come into the radiator disconnect? There are an in and out lines. I twisted the bolt off the top one and still can not get it to disconnect. The bottom one is extremely tight and I’m concerned about the same thing happening. Any insight would be greatly appreciated.

 

On my 08 gs350 awd I dont remember removing the transmission lines
I found a video on youtube that may help you out..... might want to start at 6:00

 

Hi, yes, I have seen this video however they don’t really show anything being taken apart. As you can see I uploaded a picture showing the cooling lines. I can not get them loose and I twisted off the bolt on the top one.

 

I dont see any uploads. Yes bolts can get rusted and stuck. On my water coolant reservoir I snapped one of the bolts aswell. Just make sure to buy hardware before you finish

The ac condenser you leave that alone, just separate it from the radiator. Theres no need to undo ac lines

 

Hopefully this Lexus IS video will be better detailed for you.
