I need to top up the level of coolant in my 2004 Toyota sienna which I brought to Nigeria from USA but the manual did not specify the part# but simply said "Toyota Genuine Long Life coolant" or equivalent with ethylene-glycol. I went to search on the web and saw part# 08889-80039 and 08889-80029. The one with 29 is the one I saw here in Nigeria but some of the words are in Chineese, can I use it for my American car? Please help

Can't answer your question for sure, but it is likely the same thing. Be sure to use a 50/50 mixture of antifreeze and distilled water--no tap or well water, due to minerals in the water. Otherwise, buy prediluted antifreeze.
