Today i went to Nissan here in Brissy and ask for a set of thermostat for my 350GT, he said 21200-4W01B should be the right one...that's weird..if all VQs are using the same Thermostat why 350GT is different from others.....
Check here http://www.infinitipartsusa.com/partlocator/index.cfm?action=searchCatalogOEM&siteid=55 ==>21200-31U03, G25/M37/G37 all using the same part no.
However, http://www.infinitipartsusa.com/partlocator/index.cfm?action=searchCatalogOEM&siteid=55==> 21200-4W01B , G35 ONLY???
Which is right, mates?
