Personally, I would add a lower radiator hose heater. Easier and quicker. Measure hose, buy appropriate heater,drain antifreeze, cut hose, install heater, refill radiator, burp and you are done. They work very well.
I dunno, my install was pretty quick. I would say under 20 minutes, and that includes turning the taper on my custom sleeve. I did it in the afternoon and let the sleeve retainer cure over night, and refilled the coolant in the morning. Draining and refilling the coolant is by far the most time-consuming part.
It takes 30 seconds to knock out the plug. 30 seconds to apply sleeve retainer compound. 30 seconds to tap it into place. 30 seconds to wrap Teflon tape on the heater. 1 minute to wrench in it. 10 minutes to drink a beer and admire your handy work. Quite frankly, itç—´ more work to change a headlamp in my car - I sometimes spend half an hour trying to blindly reach in and align the bulb in the socket.
If some member's dealers don't have these, are you able to send these? Should a member PM you or is their a number to call? Thank you for your help to all.
Here is the high temp sleeve retainer you will need for it.

I'm sure there are other products out there also that would suffice.
