Tested & Approved: Dorman 902-5149 Thermostat Housing Saves Infiniti/Nissan Owners Big

We recently put the Dorman 902-5149 Thermostat Housing Assembly through its paces on a 2010 Nissan Maxima that was experiencing overheating issues. This OE replacement part is engineered specifically for select Infiniti and Nissan models, and we were impressed by its perfect fitment. Installation was straightforward, taking us about an hour with basic tools.

What really stands out is the cost savings – at roughly half the price of the dealer part, we saved our test vehicle owner over $150. The housing is constructed from durable materials that match the original specifications, and includes all necessary gaskets and seals for a complete repair.

After 500 miles of testing, we’ve observed stable operating temperatures and no leaks. For Nissan and Infiniti owners facing coolant leaks or temperature regulation problems, this Dorman replacement offers reliable performance without the premium dealership markup.
