As long as your current baffle plate is removable, you should be good. The baffle plate is the part that your thermal switch/freeze switch is mounted on. We have run across some 90s models where the baffle plate is spot welded into the box.
Hello@@michaelbrewer1474 , We don't particularly like to use CFM as a comparison since we have seen some highly inaccurate CFM ratings posted online. We've done internal tests using an anemometer. The anemometer measured 330 CFM for an OEM. Our blower motor measured 380 CFM which is about a %15 increase. This is a new blower motor to new blower motor comparison not putting into the equation a used motor, corroded HVAC box, or clogged heater core/evap.
I put one of these kits in my 2013 t800 with all new everything the blower is still barely blowing air ive checked the rest of the system no plug ups wondering what else i could change
A few things to look into... Evap and heater core need to be clean. Those get blocked up pretty bad in KWs. Make sure the blower is wired correctly, black on black for ground. There's a rubber flap in the top back of the box, make sure it flaps open towards your blower motor. Make sure the blend door inside the cab isn't broken as well as the venting on the inside. Thanks and feel free to call or text the phone number on the lid if you have any further follow up questions.
I noticed that you were using “your box” in this video and not the original “factory” steel box. Do you have a video that shows the installation of the “blower upgrade kit” being added to the “factory original” steel box? (I have a 2011 and a 2013 KW T660 and would like to upgrade the blowers on both trucks without replacing the factory steel boxes) Is this possible?
@calsmith7902 thank you for the comment. We don't have a video with a factory box since we didn't have one handy when we made this video. The installation would basically be the same in any OEM box with minor differences. The Upgrade Kit will work for both of your T660s, thanks!
Yes, but you do have to keep in mind that the blower motor is just a part of KW air flow issues. Make sure your heater core and evap is clean. They typically get clogged with dirt. Also, if your box is rusted out, you will have a lot of air leaking out of the box. Outside of these things, the Upgrade Kit will blow harder than an OEM blower.
I have a 1991 kenworth t450 and I hope this will fix my weak blowing ac

Also, check the usual, make sure your heater core and evap aren't clogged or your box is so rusted that it is losing air.
Does the blower motor turn at a higher RPM? How many more CFM of air flow do you get? Thank you😊

I will check the condition of my current boxes .... and let you know.
Thx Cal
@@calsmith7902 Sounds good.
Will this blow more air than the original??
