I know it has been a thread topic already. The search doesn't bring anything up. I know SLP has a pretty sweet gauge by KOSO. Is there another one out there and where does it plum into the coolant system? Thanks in advance.

It depends on what you want to measure. I placed mine in the coolant bypass hose. This is the hose that comes off the water pump and goes towards the front of the sled. It is a fairly small diameter hose, and after it goes around the front corner of the motor it goes into the oil cooler (which is what the oil filter mounts to).
By mounting it in the bypass you are measuring coolant temp going into the motor. Also, because the bypass always has coolant flowing you can determine coolant temp even with the thermostat closed.

Here's the thread I created after I installed my gauge. Btw, after having it on all season I've not had a problem with leaks, broken wires, or anything like that.

You'll notice that the diagnostic mode of the Deluxe gauge doesn't give information in C or F, but instead is just the raw output of the A/D converter they use in the microprocessor. There's another thread I created about that. You can still use the diagnostic temp, but you need know what normal is for the number range it reads. Plus you cannot get out of diagnostic mode unless you restart the sled.

Something to be aware of in regards to the 1100t cooling system we have found both on the dyno and on the trail. The stock settings for the coolant idiot light to go on and start the stock ECU into a safety mode are very close to engine melt down. Meaning, if your coolant light goes off, stop immediately! Usually about the same time the light goes on, the motor goes clunk and you get out a tow strap. That's one of the many things we changed on all Evolution ECU reflashes. The safety point for engine temps is reduced on all Evolution reflashed ECU's regardless of HP level. This gives you a large safety cushion between the time the light goes on and the pistons become part of the cylinder walls.
I want one to know how warm\hot the engine is running. So I'd want in the line headed to the cooler. Right?
Well that is stupid that you will boil over before the idiot light will come on. I know last year I got mine pretty hot a couple of time and I want a way to know how hot. Never did see a temp light though.
Thanks for the link izzni. Good stuff there.

Yup. The temp will be the water going into the motor, whether or not the Thermostat is closed.
This is what I am thinking also. I want to know the actual temp of the engine.
Is anyone using the koso gauge?
