A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 2003+ Toyota 4Runner 4.0L cooling system with a Mishimoto Low-Temperature Racing Thermostat and housing! This thermostat is designed as a direct-fit replacement for your aged stock unit. The Mishimoto thermostat has a lower activation temperature (71?C/160?F) compared to the factory thermostat (82?C/180?F). The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates, on vehicles making more power than stock, or under extreme towing/driving conditions. The stock-style housing will provide a proper seal and installs easily. Like all our Toyota Performance parts, this thermostat and housing includes the Mishimoto Lifetime Warranty.This Part Fits:

My puppy loves this chew toy.
Style: Goal Post Chew Toy, Color: Detroit Lions
It’s one of his favorite toys to show off and chew. I constantly find him carrying it around. The only downside is that the Lions emblem wore off really quickly. It’s still a super cool toy though.

Heavy nylon. No squishy or chewable for pups.
Style: Goal Post Chew Toy, Color: PHILADELPHIA EAGLES, Style: Goal Post Chew Toy, Color: PHILADELPHIA EAGLES
Photo is just for size comparison. It’s really hard and not chewable but he’s already put a dent into it, as you can see. Not sticky, smells right out of the packaging !! We loved that! Its size is about a 20 oz Powerdrink but it’s sturdy and heavy. It’s going to last us such a long time .
The only thing is the logo might be worn off sometime soon. Go birds! 🦅

Perfect toy for an active dog!
Color: Large size (7.9")
My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play.
The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing.
I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out.
Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾

Not for strong chewers!
Color: Large size (7.9")
I have an English Springer Spaniel who is 1.5 yrs. She had this torn apart within the first 5 minutes. This is not for strong chewers!
