We have looked into our thermostatic sandwich plate to determine the exact source of the issue. Our engineers met last week with an O-ring sealing specialist from Parker to further examine the issue and have traced it to a small batch of inconsistent O-rings. These O-rings did not allow for the thermostat plug to be fully tightened. This is limited to just the most recent production lot of our thermostatic sandwich plates, and we are implementing several changes to address the issue.
We have immediately severed the relationship with the previous O-ring supplier, and will be using Parker O-rings for this product moving forward. They are higher quality and more reliable.
We have pulled all inventory of thermostatic sandwich plates from our warehouse and they are currently being re-worked by engineers in our Delaware office before being returned to stock.
We are adding a caution sticker to future production packaging to remind the user to double-check all plugs and fittings to assure they are fully tightened before running the vehicle. We are adding this information to our website as well.
If you currently own a Mishimoto Thermostatic Sandwich plate, and would like a replacement O-ring, please contact
sales@mishimoto.com and we will send you a new one free of charge. Even if you are currently running our Thermostatic plate with no problem, and just want peace of mind.
We apologize for any inconveniences this may have caused, and will make sure that the quality of our products stand up to our expectations.
