I'd agree with 3 minutes. I don't remember any coolant loss at all. Disconnect the electric (I did, anyway), take out the 4 screws, pull the bad guts out, put the new one in, reconnect elec., drive forth in warmth. I think I even took it off the firewall, and it was still under 5 minutes. Wish all repairs were that easy. I got my replacement at *************** for about $35. If I could figure out how to replace the rubber diaphragm that's bad in my old one, I'd fix it for a back up, but so far I haven't figured out where to get them. Don't know if it's possible to do yourself or not, but I still have my old one, just in case. Why not take some pics and put it on the DIY page when you replace it? Wish I would have. Like rocky racoon said, you could snap a picture and drink a beer between each step. (All 3 of them)
