Description

Radium RADIATOR CAP, TYPE-A, 1.5BAR, BLACKThe radiator cap is an essential part of an upgraded cooling system. Radium caps are engineered to safely improve cooling efficiency by managing the boiling temperature. A higher radiator pressure effectively raises the coolant boiling point, providing an extra safety margin and preventing air pocket cavitation at the water pump. NOTE: Traditionally, "radiator" caps are mounted to the radiator but can also be found on coolant expansion tanks (below).

Each OEM replacement radiator cap is manufactured from stamped stainless steel for durability. All 18-0076-X1X radiator caps are electroplated black.

Unlike OEM caps which use natural rubber gaskets, these radiator caps feature premium silicone sealing elements for long lasting durability.

Not helpful
Format: Paperback
This book is so basic it doesn't really help much in tips on identifying rocks and minerals. The photos are enlarged so much they are distorted and most photos are of the rocks cleaned and polished. That doesn't help with how to spot things in nature or where to look. I'm really disappointed. Also, Montana has a lot of cool rocks but all books ever speak of are sapphires and agates. I feel like I wasted my money. There are some helpful things but even as a beginner, most of the contents are known.

my spirit guardian
Format: Kindle
I am watching a practice witchcraft. Right after I started practicing witchcraft my spirit guardian came to me in a visit. She is an old medicine woman from an indigenous tribe. I also have two other spirit guardians both or former pets that were killed. They are my protectors. However, the spirit guardian that came to me in the vision. She is the one that brings me warning, gives me my spells, helps me with virtually everything into my day-to-day living. I found it ironic that I came across this book whenever whenever it showed in my recommended reading list. But I digress, the first few paragraphs told me everything that I already knew and brought confirmation to what my spirit guardian had already told me. I flip through the book read a few things. I personally do not believe in angels, but I do believe that if you are willing to open yourself up your guardian will be they’re guiding you the entire time. One particular example that I would like to give. A few days ago I’ve gotten up and I stood by my altar to do my morning magic. As I started the ritual, I felt this fear come over me and started in my guts. This is the area where my spirit guardian warns me and tells me not to do something. At that point I felt or it was pressed upon me that I needed to hurry up and get dressed and start my day. I drive rideshare, Uber I heard up got dressed and I thought point I felt like not to make any noise in my house. I quickly left my house went to my car got it warmed up as fast as I possibly could and left. The moment I left my property because I live in the country and got on the road that fear left. After meditating on it I have to believe that my spirit garden was protecting me from a dark force that was coming for me. That I needed to leave the property as fast as I could because I was in danger
