Manufactured by Adapt Lab 

“THIS RESTRICTOR FITS THE FOLLOWING UZ ENGINES WITH THE WATER INLET HOUSING SHOWN IN THE PHOTOS ABOVE. THIS SHOULD CONSIST OF 1UZ NON VVTI, 2UZ VVTI, 3UZ VVTI.”

The Coolant Bypass Restrictor for the UZ family of engines was created to help push the performance capabilities of the engine. It is not solely about lowering temperatures but controlling the engine temperatures. The coolant range is still at OEM operating temperatures but never getting to a point that could damage the engine. It is a solution to many while being simple and effective. What is included is a Billet Aluminum restrictor that is designed to be tolerance fit into the thermostat housing.

Read more details

In testing the coolant bypass restrictor (paired with the OEM thermostat) has placed the operating range of the coolant temperature of the engine at 190-200F (88-93C) in cruising, spirited driving, drifting or track sessions while still retaining a quick warm up time like OEM.

WARNINGS:
1) A colder thermostat ALONE will not have the same result as the coolant bypass restrictor but using a 170F (76C) thermostat WITH the restrictor will maintain your temperatures in the 183-193F (84-89C) range.
2) Corrosion in your coolant system may cause fitment issues when installing the restrictor. Lightly sanding and cleaning the inlet is highly recommended before installing.
3) A Dead Blow Hammer is highly recommended when installing the restrictor into the housing to prevent damage to the restrictor or the housing. The restrictor should be pushed in by hand as much as possible before using the Dead Blow Hammer to get a flush fitment.

The Coolant Bypass Restrictor fits the following models:
-1UZ-FE Non VVTI

-2UZ-FE VVTI

-3UZ-FE VVTI

*If you have the housing with a removable 2 bolt side barb (as pictured with red X ) then this WILL NOT FIT. (which has been found on 1UZ VVTI and 2UZ Non VVTI engines).

Our Pit Bull’s Favorite Toy!
Color: A-Navy, Color: A-Navy
We absolutely love this MAXBECK bear toy! We’ve ordered it 4 times over the last 8 months because our senior pit bull is obsessed with his “babies.” He always has one close to him and even cuddles with them. The material is very sturdy and holds up amazingly well even with rough play. My dog’s favorite part is the squeaker. What I love most is that even after he finally tears into it, the rope built inside becomes a whole second toy for him and keeps the fun going. If you have a heavy chewer who destroys toys quickly, this one is definitely worth trying!

Not indestructible
Color: C-Navy+Oak, Color: C-Navy+Oak
I assume it is probably hard to create an indestructible product, but my puppy had it apart in no time.

NOT DURABLE, LONG-LASTING, OR USEFUL
Color: A-Navy, Color: A-Navy
I gave this dog toy 2-stars based on my dog toy rating system (DTRS) for “Albert” the Blue Bear! Safety (1-rating): Albert fell apart after 4-hours of use. 1. The ears were chewed off and I was only able to find one of them, which means my dog swallowed the other ear. Very big concern as it depends on how big your dog is to pass this object. The ear is about the size of 1.5-quarters. 2. The tail was almost chewed off entirely and was hanging on by a thread before I threw it out. 3. After the ears came off, the inside foam started to come out, which raised my concern for my dog’s saftey. 4. The entire body was soft and did not cause any harm to teeth, gums, paws, nose, etc. Durability (3-rating): 1. The ears and tail are the weakest parts of Albert as they can easily be chewed off. 2. The body is durable enough to sustain 4-hours of use, as I threw Albert out after the ears and tail were torn off within 4-hours. 3. The small squeaker inside Albert’s belly was broken after 15-minutes of use. Thank Goodness! 4. My next concern was how long the arms and legs would last; TBD! Squeaker (1-rating): 1. Small plastic squeaker, the size of a half-dollar, with a high pitched noise. Fatality (2-rating): 1. Albert was put to rest after 4-hours of use as I was concerned for the safety of my dog with continued use. 2. If Albert didn’t come with ears or a tail, I can only imagine how long he would’ve survived as the material seemed to be durable enough to withstand continued use. In conclusion, “Albert” the Blue Bear is not worth the money for a toy that falls apart after 4-hrs of use and with the concerns of safety. I was surprised that it was only 8-inches tall, next time I’ll confirm the size of the toy before I purchase the next one. About my dog “Cannoli” for comparison: Breed: Blue Healer / Lab mix Weight: 40-lbs Energy Level: High Age: 7-months Chew Rating: Aggressive

The dog won!
Color: A-Navy, Color: A-Navy
It’s not indestructible. Wonder if I can get a refund or another toy. It did last longer than most so I give them credit for that!

Almost good enough
Color: E-Navy+Purple
My dog chewy can rip through anything, even these. I do love the toys they’re great. They’re made with coconut on the inside, but could somebody please!, make a chew toy worthy of my dogs teeth, cause this ain’t it. But it is the strongest so far . I would recommend it. My doodle chewy short for Chewbacca is insane about chewing.
