Hi,
I am trying very hard (or I should say my computer wiz friend) to try and get my digital camera to work on my computer ...hopfully pics soon. Part #40039 NAPA - and yes it is called a Tank Heater. Part #above if for a 1000W - there is a 1500W available too I think, which I would have no worries installing either as it supposed to get to -34 here by Friday ...damn. Hope this helps, and yes, Dude I did get you message. Find your block drain - it is behind the turbo on the 12HT (you have to get underneath to see it)
Go to Napa get your heater, and also :
3/8 NPT threaded on both ends
a 40 degree elbow 3/8
a 3/8 to 5/8 adapter
then 5/8 nipple
6 feet of hi-temp 5/8 heater hose
5/8 3 way tee (I used copper)
bunch of SS hose clamps
going 3/8 to 5/8 doesnt seem to starve to heater - I was worried about that.....
get all fittings teflon taped and ready BEFORE removing bklock drain. use elbow to aim to inlet hose well out of way of turbo (towards where you want the heater to be). Keep it low as possibel and vertical. Tap outlet (hot end) into the bypass hose - I reomved the stock hose and built a new one with the 3 way tee that provided the outlet to get plugged into the highest possible point on the block. I'll try and take a pic of this and get it on here. Read the suppied instructions too! If in doubt or dont want the coolant mess when tapping block drain, then take to mechanic - should be 1hr job. Hope this helps you guys!
