- Compare the 116mm flange diameter against the original pump before fitting.

- Clean the mating surface on the engine block thoroughly before fitting the new pump.
- Refill with the correct coolant specification and bleed the cooling system to remove air pockets.

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned.
These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.

Super fun, easy to use, and beautiful!
Color: Sparkling Pink
Love it! I can’t stop thinking of excuses to wear it just in my day-to-day life because I love how it looks so much. I put it on my cheekbones, nose, and collarbones, and I also put it on over my eyes like an eyeshadow and it worked really well for that too. It’s super easy to use and intuitive, you just roll it on. It didn’t bother my skin either, which some glitters do because I have sensitive skin. Comes off easily with water and a washcloth, although some of it hangs around and you have to take it off with makeup remover, but that’s no problem for me honestly. It does rub off a bit, so be prepared for whatever you wear with it to get a little glittery. Great product, recommend!
