Just did this exact same job with the same aluminum T's I ordered from the link. Just a few words caution or advice I would offer:
The two ends of the T that are in a straight line (the top of the T) are the exact same size as the orginal plastic. The other leg of the T is smaller on the original plastic T by about 1/16th so when using the aluminum you will find that it is extremely tight to get the new piece in place. I sanded down the aluminum pipe where it goes into the slightly ly smaller line and it was much easier. Also, the plastic was very brittle and crumbled with finger pressure. Be careful not to get these sharp plastic particles in your coolant lines. I had to dig out the broken ends of the old plastic T's from the rubber hoses. I used about 1 full jug of coolant plus about another quart. Finally, if you have skid plates your coolant lines should be protected and the delicate plastic T's should not be an issue however one of mine was so brittle I am glad it is off my truck and I do have better peace of mind.
