opus Posted December 21, 2008 Share Posted December 21, 2008 What is the best way to go. I like bottle heaters best. Freeze plug heaters the least. Suggestions for an ea81 and an ea82 needed. Quote Link to comment Share on other sites More sharing options...

Pontiac6KSTEAWD Posted December 21, 2008 Share Posted December 21, 2008 I personally prefer the In Line heaters with pumps. They circulate the warmed antifreeze thru the entire engine, and because of the radiational affect, it also warms the oil. And because of the coolant bypass system that all cars have, the coolant thru the whole engine, radiator, heater core, will be warmed to about 90 degrees. It also means less snow clearing in the hood area. Its also the easiest to install. Can be done, with a cold engine, in about 20 minutes.

What particular model heater and where do you end up putting it, under the spare, in the heater hose? Quote Link to comment Share on other sites More sharing options...
Pontiac6KSTEAWD Posted December 22, 2008 Share Posted December 22, 2008 I beleive this is the style, althou I dont remember exactly. Was 3 years ago that I installed it. I would have to contact the seller to see if this is the pump style, althou it looks like it is. But I am not sure. http://cgi.ebay.com/Engine-Block-Heater-Tank-Type-1500W-Cold-Start-Warmer_W0QQitemZ250339166614QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l1116 Yes it does go into the heater core lines. I do not like the ones that go into the main radiator hoses. Silt, and other things can form on the heater elements over time, and drasticly reduce the coolant flow. In the heater core lines, you will notice a slight diference in the amount of heat that comes out of the vents as the silt builds, but will not affect how the engine is cooled. If memory serves me right, we bought 5 feet of heater core hose from a parts store, and took the old one out completely. Mounted the pump/warmer in front of the strut tower with a strap. Then used the new heater core hose to connect it all together. This was on a 94 legacy, so there was no spare tire under the hood. Althou I imagine it could easily be mounted under the spare tire, using the spare tire carrier shelf as a mounting point. Quote Link to comment Share on other sites More sharing options...

opus Posted December 22, 2008 Author Share Posted December 22, 2008 Popping out a freeze plug is not really an option for me at 0 degrees outside. Quote Link to comment Share on other sites More sharing options...

opus Posted December 22, 2008 Author Share Posted December 22, 2008 Have you a part number for the heater? I assume it is a threaded block heater that goes in the hole? Without looking, I am guessing it is the big plug on the front. I wonder what it will take to get that out. Quote Link to comment Share on other sites More sharing options...
mdjdc Posted December 22, 2008 Share Posted December 22, 2008 If one from an EJ 25 block will fit, then I have one with the wires you will need to plug it in. Installation is really simple. Make me an offer and I can pull it from my spare engine and send it to you . You will save a bunch over buying new. I can even submerge it in a bucket of water and make sure it is fully functional.

opus Posted December 23, 2008 Author Share Posted December 23, 2008 Thanks but at $27, I figure I would buy one for each rig. Thanks for the offer. Now....what to use to take the plug out. :/ Quote Link to comment Share on other sites More sharing options...

opus Posted December 23, 2008 Author Share Posted December 23, 2008 I have no outlet for tools. I searched and looks like you cant buy Cornwall tools online. I do have a 3/4 impact gun though. Anyone make a tool for plug removal? Quote Link to comment Share on other sites More sharing options...
Pontiac6KSTEAWD Posted December 23, 2008 Share Posted December 23, 2008 From my local parts store, I found the part number, and maker. Maker - ZeroStat Part # 33080002 Was like 50 bucks, this is the warmer, with a circulation pump. Quote Link to comment Share on other sites More sharing options...
Txakura Posted December 23, 2008 Share Posted December 23, 2008 (edited) I just picked up a 1000 Watt 'Kat's' recirculating coolant heater from Schuck's for $30. It looks to be a pain, it has to be mounted low, bled thoroughly and preferably tied into the block drain and fed back to the water pump inlet. It comes with clamps, some fittings, and a mounting bracket. It's 110v for cold nights. Maker "Five Star MFG. Co. 'Kat's Heaters'" part number 12100 I'm in the same boat, it's -2 F outside, and I need it badly, but really really don't want to deal with installing it in the snow. Oh, I'm a newbie to the bbs, hello to everybody. Edited December 23, 2008 by Txakura Quote Link to comment Share on other sites More sharing options...

elBradford Posted January 15, 2011 Share Posted January 15, 2011 (edited) it's not a freeze plug!!!!! for ea71 and ea81 the plug is on the front of the block to the left of the crankshaft for ea82 the plug is on the bottom of the block below the oil fill tube use a 14mm bit to remove the plug is 36mm thread BTDT on ea71 ea81 ea82 I'm sorry to resurrect a 2 year old thread! But I need some clarification. The mounting port is 36mm threaded? I can't find any threaded engine block heaters for my 1994 Subaru Loyale, just this that supposedly fits: Kats 11405, however that is the rubber gasket style. Thanks for any feedback, I need to get this guy warm before my daily 5:00 am drives. Also, I found this PDF that shows where to mount the heater. Is this correct?
