***EXTREMELY IMPORTANT*** THE ENGINE MUST BE COOL PRIOR TO INSTALLATION OF THIS PRODUCT.
1. Park your MINI in a level, well-lit area and pop your hood. It’s a good habit to disconnect the negative (-) battery terminal anytime you’re working around your MINI, so grab your trusty 10mm socket and do this now.
2. Utilizing your 8mm socket wrench, remove the coolant overflow tank on the front, driver side of the engine compartment. You can either choose to work around it, or drain the coolant from it and temporarily remove it from your MINI. Once empty, pry the wire clip out a bit and disconnect the plastic elbow from the underside.
3. Now that you have access to the area underneath the coolant overflow, locate the coolant hose alongside the outer engine compartment wall and you should see a plastic inline coupler. The CravenSpeed Hot Link simply replaces this coupler. In the manual transmission MINIs this coupler is straight, but in automatics this coupler has a smaller t-fitting in the center that goes to the transmission. See image below.
4. Prepare the Hot Link by applying some thread sealant/teflon tape to the threads of your gauge temp sender (included with your gauge kit) and install it into the smaller of the two threaded holes. For manual transmission MINIs, install the ⅜ brass plug with a 5/16 hex driver into the remaining threaded hole utilizing your preferred thread sealant. For automatic transmission MINIs, install the ⅝ brass barbed hose fitting using your thread sealant.
5. For this next step, be prepared to spill a bit of coolant (like a half gallon worth, so prepare yourself). Place a drain pan on the floor directly underneath your work area to catch the mess you’re about to create. Use coolant hose pinch pliers if you have them, otherwise recruit a friend to help stem the flow of coolant while you remove the factory hose coupler. You can loosen the factory hose clamps with an adjustable wrench by pinching the metal ends together. Remove the two main factory hose clamps as we’ve provided higher quality units in this kit. For automatics, reuse the hose clamp from that fitting if there is one.
6. With the factory hose coupler removed, slip the included hose clamps loosely over the coolant hoses and then install the CravenSpeed Hot Link, pushing the hoses all the way up against the center section of the Hot Link housing. Slip the hose clamps into position and tighten.
7. Perform the necessary wiring as outlined in your gauge instructions. Replace your coolant overflow tank hose and reattach it to the front core support.
8. If you’ve lost very much coolant over the course of this install, top it back off with what’s recommended by the factory. Reconnect your battery (-) terminal and tidy up your work area.
NOTE: Please be sure to clean up any spilled coolant that may be left on the ground as it is extremely harmful to our furry friends.
