Product Details

The Dorman 902-5040 Engine Coolant Thermostat Housing is a direct-fit replacement designed to restore proper coolant flow and protect your engine from overheating. Engineered to match the fit and function of the original equipment housing, this metal construction unit is built to last through the demanding thermal cycles of daily driving.

Original thermostat housings are prone to becoming brittle over time due to repeated exposure to extreme heat and cold, leading to cracks and coolant leaks. The Dorman 902-5040 addresses these common failure points with durable metal construction specifically engineered to resist temperature-induced degradation, cracking, and leaking.

Key Features:

  • Direct OE Replacement – Engineered to match the fit and durability of the stock thermostat housing
  • Durable Metal Construction – Resists the extreme temperature changes that cause brittle failures and coolant leaks
  • Air Bleeder Valve Included – Integrated bleeder valve helps purge air pockets from the cooling system
  • Gasket/Seal Included – Comes with the necessary seal for a complete, leak-free installation
  • 90° Housing Neck Angle – Matches OE geometry for proper hose routing and fit
  • 3 Mounting Holes – 0.313 in. mounting hole diameter for secure, stable installation
  • Cost-Effective Alternative – Delivers dealer-quality fit and durability at an aftermarket price

Dorman has been an industry leader in aftermarket replacement parts for over 100 years, engineering solutions that save time and money while maintaining reliable performance. The 902-5040 thermostat housing undergoes rigorous quality testing to ensure long-term reliability in your cooling system.

Excellent service good price and good attention excellent products

Happy you still had the part after all these years! Thanks

The description for the product is wrong. This is an 8 bolt posi and you advertise 10 bolt. I have the product I wanted (8 bolt) bc I knew what part number I was looking for, but it's still confusing when the description says its 10 bolt.

I was pleasantly surprised to received my order the following day.With ground shipping I was hoping to get it in 4 days to 6 days but this is amazing.You guys are great, thank you.

Great prices and easy payment options.

I had a smog guy call me out that my filter was ok, my truck passed but since my pipe wasn't name brand we wouldn't pass me. It's a 2008 Nissan Titan. Needless to say I wasn't to happy about it but this place had what I needed for about $50 less than anywhere else and it shipped within 2 days. So far, so good, thanks Autoplicity
