Just did some searching because it seems mine is burnt out and found that KAT made by Five Star Manufacturing seems to be a popular brand. All 3 are showing in stock at my local Napa.

From their catalog what they list for the 6.5's:

10612 permanent frost plug heater (not sure what this is or who sells them)
11612 removable frost plug heater approx $26
notes, installed 12 o clock position left center hole 600 watts

14700 Lower radiator hose 600 watts approx $40
13150 external tank 1500 watts approx $75

here is the link to the page where you can get their catalog:

98 Burb K25 4.10's 250K miles, new to me, pretty clean and stock.
95 Burb K25 4.10's 250K miles, looks to have been rebuilt at least once, stock, bad rust, DE exhaust w/walker muffler, 8' western plow.
81 Buick Riviera with the infamous Olds 5.7 diesel still going strong.
15 VW Golf wagon, TDI. Did the buyback on my 13 Jetta TDI wagon so it was basically a trade up.
96 Burb K25 3.42's SOLD at 340K miles, told it was all original, close race between engine wearing out or body completely rust out.

After contemplating this some more I remembered that a few years back I bought an inline coolant heater at a garage sale. Sure enough, with some digging in the garage, I found it. It's an oldie, but that probably explains why it actually still works.

It's 800 watts, so I think I'll go with a 600w block heater in addition to this which will about max out a standard 15A receptacle.

Now I just have to find time to get this done.... :-/
