SLP coolant bypass

When installing the bypass are you suppose to plug the existing coolant line that goes into the head or what? and if so with what? I'm confused, maybe I'm just missing something in the instructions. Sled is an 08 D8 btw. Thanks in advance for any input!
 
the existing one is your main with the thermostat, your just bypassing that till ur thermo opens, or am i missing what your asking?

bypass

The small line that comes from the throttle body heater gets cut and a "T" installed in the line. Remove the plug in the head and attach it to the "T" with the small piece of hose. Idea here is to get the coolant moving on the mag side head. Seems to be a dead spot on that side with coolant circulation.

Correct. I would only add that it's the Mag side throttle body coolant hose that routes to the coolant reservoir that gets cut. Install the Tee so that the Tee side of the Tee (the perpindicular outlet) goes to the reservoir. Great, simple idea.
 
Made my own coolant bypass kit. Brass fittings, T & a straight one, 3 clamps and a 6" piece of coolant hose. $10.
 
Made my own also. I t'ed In the 1" main return with the belief that i would get more flow out of two seperate lines rather that two into one at the resevior. if that makes sence
 
any pics of the home made by pass?

Is anybody willing to post some pictures and descriptions of their home made by pass kit? I would like to make one myself. Thanks in advance!!!

Alright.. so do you guys see my problem here? I have a 1/2 inch hose coming off where theres suppose to be a plug, but theres a hose attached.. So where is that hose suppose to go? Or am i just missing something?
 
I will have to take a look at my 08 tonight when I get home. I do remember that the 08 coolant routing was different than 09-10. This is curious as I don't readily see how the bypass could work on your sled.

OK, in 2008 there is definitely a hose already occupying that location. I don't think the coolant bypass is applicable to the 2008 model. I would contact SLP. I believe they may have an issue with their application on this one.

Here are some Pics of my homemade kit on an '09 RMK Dragon. Power Addiction head also helps with coolant circulation through the head. Hope the pics help.

Alright talked to the slp tech rep down at the snow show last night. The bypass kit will NOT work on an 08 dragon. Although if you have a late model 08 they will.. He said I shouldn't have the problem... But I still watch my temp shoot down about 50 degrees...

Thanks for the update! Are you referring to start up? I still say that is pretty normal. When you shut off the engine your temp will rise. When the coolant starts to flow it will equalize again. Fan cooled, liquid cooled, your car or whatever, this is normal. It has always been a good practice to just give it a couple seconds to get the juices flowing before you start hammering the throttle.

You are right on that MT. As an example, today after running 126 and just sitting for a few minutes, starting back up was 145ish and then back to 120ish and good to go. With my resent piston update that is all I watch on the trail is the temp gauge.
