I have a spill proof coolant funnel kit for $8. I purchased this kit on Amazon for complete coolant hose replacement, flush and refill. I used it one time for the coolant flush and refill process and it worked perfectly. The kit comes with multiple cap attachments to accommodate most applications. It makes the process of removing air pockets in cooling systems a breeze. You fill funnel with new coolant unit it stops bubbling. The funnel has a shutoff valve so any remaining coolant in funnel can be put back into the original jug without spilling a drop. I don’t see myself needing this kit in the foreseeable future. My garage has limited storage space so I’m offering it up for $8. I think I paid $25 for it. The kit is complete and was used for one flush/fill. Changing your own hoses and coolant is fairly easy and can save you a lot of money versus paying repair shop or dealership.
