“THIS BYPASS DELETE 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 Delete for the UZ family of engines was created to help push the performance capabilities of the engine in extreme conditions. It is not solely about lowering temperatures but controlling the engine temperatures. It is a solution for extreme performance while being simple and effective. What is included is a Billet Aluminum Bypass Delete that is designed to be tolerance fit into the thermostat housing.

In testing the coolant bypass delete has placed the operating range of the coolant temperature in conjunction with the fan activation and deactivation being completely reliant on the effectiveness of your radiator and fan combo. Example: If your fan is set to turn on at 200f and shut off at 185f then engine temperatures will follow this. If your fans turn on at 210f and shut off at 205f, then your coolant temperatures will follow that.

WARNINGS:
1) This coolant bypass delete is also a thermostat delete. DO NOT ATTEMPT TO RUN THIS WITH A THERMOSTAT! You must run this with the provided thermostat delete plate.
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 delete into the housing to prevent damage to the delete or the housing. The delete should be pushed in by hand as much as possible before using the Dead Blow Hammer to get a flush fitment.

The Coolant Bypass Delete 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 below) then this WILL NOT FIT. (which has been found on 1UZ VVTI and 2UZ Non VVTI engines). Please replace water inlet housing and use part number 16032-50110.

Didn’t hold its shape after 1 month.
Item Package Quantity: 4, Size: Queen
been using this pillow for about a month now, and here’s my honest take. At first, it was super comfortable — soft, supportive, and perfect for getting a good night’s sleep. It gave great neck support and felt like a solid upgrade. But after a few weeks, I did notice it started to lose its shape a bit. It’s still comfortable, just not as supportive as when I first got it. I find myself fluffing it more often now.

Pillow for everyone
Item Package Quantity: 2, Size: Queen
I think this pillow is too firm. I prefer a softer pillow but wanted to try this one. I may just have to get use to it. I will keep using it and see if I cannot get use to it.

Gonna get more for the guest room while I'm thinking about it.
Item Package Quantity: 4, Size: Queen
I will buy these again in a few years. I got 2 for me, and two for my man. They look super nice and full, and squish perfectly when you lay your head down on them. They are economical and priced nicely. They fluff decent when you fluff them, and I love my pillows again. These got rid of my headaches from neck trouble. I love these pillows. I'm gonna actually buy some right now for my guest room while I'm thinking about it. I compare these to that hotel I slept at once that had the most amazing pillows. Clean crisp fresh and soft. But not too soft. They are definitely soft, but cradle your head like a hug.

Well made and soft Resilient but not memory foam Good for back or tummy sleeper
Item Package Quantity: 4, Size: Queen
These pillows are well made I put them in the dryer on medium heat for 10 min 2 at a time, and they doubled in fluffiness They're soft to the touch as well as in plushness/depth They are resilient but not memory foam I don't think they would be firm enough for a side sleeper but nice for resting on your back or tummy
