If you are getting coolant out the seal... it's time for a rebuild. The main coolant seal is behind two bearings. Coolant is now contaminated your grease. I just rebuilt mine 1 year ago. I SCOURED the earth for a rebuilt pump. "sorry, obsolete". Interstate McBee offers a kit. You'll get EVERYTHING. Bearings, seals, impeller, shaft, snap rings... If you need, I can scan the rebuild process to you. Lots of press work, and I could loan you the seal depth setting tool. Edit; #9 shows a grease seal. In the kit, the bearings are self contained sealed. The original oem bearings were open both sides. I popped out the inboard seals, and allowed for grease to flow into bearing,
