Canadian number for thermostat on a 2000

[JMartin]

According to the tech WIKI "Part number for a Duralast 180 degree thermostat is #15858. It is suppose to fit the 2000, 1600, 240z, and 510. "

I can't seem to cross that to a Stant number for Canada. I was hoping to get one from a local auto parts store instead of going through Nissan (if even available)

I did get a Stant one a couple weeks ago, but it just doesn't look right. I don't have a picture of it right now, but it sure looks like an offset type thermostat. Anyone have a number for a Canadian one (napa, Stant, etc)

I have a Stant 45358 in my 2000. It is 180 degrees.

I was sold a Stant 13858. Look at the photo, the center is offset. I don't remember the Roadster thermostat being offset. I want to only drain the coolant once, and not do the job twice!

I got one from Nissan just a few weeks ago.

I save all my boxes....never want to research twice when I got it right the 1st time

[JMartin]

Thanks, I will check with a local supplier to see if that number is available in Canada.

Greg or others;

I found the Stant 45358 at my local auto parts store. It looks right (its not offset like the previous one I was shown). The parts guy mentioned that the Stant 13858 (the offset one) has a relief valve in it. He said that some cars required them in case they got too hot.

Anyone else besides Greg know if they are using the Stant 45358, or should I be using the offset one in my 69 2000.

I have a Nissan 180* Thermostat in my car and it is offset like your picture. I can't see that any offset would affect how it works....or think of a reason it would or would not be offset........

[JMartin]

Thanks Daryl;

I couldn't understand why or why not to use the offset one. I kind of liked the idea of a pressure relief valve on the rim of it.
Will you make it to Kelowna this week?

Hmmm. I like the relief valve idea. I don't think I will change mine out but if I bought again. I would look for that.

I am hoping to put the offset relief type one in my car tonight. I plan to drive it to Kelowna, but I don't have the temp guage working right, so I figured I had better just change the old one out. I will let you know if there's an issue, but as long as I use the right gasket with the metal staple in it, it should be fine.

[Daryl Smith]

I'm coming for sure, but worried about whether the car is gonna .....have to put the rear diff and brakes in tonight....Now, back to the garage......

[JMartin]

yup, me too. Just found an upper rad hose from DAYCO part number 70986 1 5/16" ID seems too small, but we will check it in a bit.

[JMartin]

I installed the thermostat tonight, and replaced both upper and lower rad hoses. I ordered a lower hose from Ross, (the Gates one on the wiki), and it fit perfectly. I had a heck of a time finding the upper, but it turns out that it crossed fine to a DAYCO 70986. You will see that it is a little long, but a good knife blade took care of that.

I took several photos of the original braided type hose to the replacement hoses

Unlike conventional thermostats that continually open and close to achieve the proper operating temperature and flood the engine with coolant, the Stant SuperStat® thermostat has a unique v-notch, non-linear design that reduces cycling by precisely metering the amount of coolant needed to maintain proper operating temperature.

The v-notch provides a small initial flow. As the engine heats up, the v-notch gradually opens wider, metering coolant into the system until the desired engine temperature is reached.
The benefits of proper engine temperature are: efficient engine operation
prolonged engine life
reduced oil consumption
improved fuel economy and reduced emissions

Stant's SuperStat® uses a high flow venturi for maximum cooling capacity during high temperature, high load operation and employs a unique Weir Valve® for precise flow metering during cold weather, light load operation to ensure stable temperature control under all conditions.

The high strength stainless steel flange is burnished to a bright finish for additional stress relief and added corrosion resistance.

The Stant SuperStat® thermostat is also thicker than most competitor thermostats and our standard reverse poppet thermostat for added strength and longer life.

The power element of SuperStat® is comparable to those used in heavy-duty trucks. Its actuator piston is larger in diameter than the standard thermostat and competitive product. This larger piston delivers 1 1/2 times the power of our standard thermostat and almost 2 1/2 times as much power as the competition for enhanced durability and longer life.

The opening spring of the Stant SuperStat® thermostat is designed with a load that is 50% stronger than our standard reverse poppet thermostat. This heavy-duty spring helps return the thermostat to the closed position and prevent cold running, even under the most adverse conditions. Features and Benefits

Upgrades over OE equivalent thermostats offer more efficient temperature control resulting in faster warm-ups, better fuel economy, and longer engine life.
Limited lifetime warranty.
OE supplier experience results in a match in fit and function when a replacement part is needed.
Technologically advanced designs use bleed notches, check valves, and other methods to assist in releasing air from the cooling system.
Uniue Weir valve technology allows for a smooth and gradual flow of coolant so the engine reaches its optimal temperature more quickly, resulting in improved performance, including better fuel efficiency.
Heavier-grade stainless steel housing for high-flow engines for longer life and durability.
Long-lasting, stronger spring closes valve faster for better temperature control.
Larger heat motor reacts to temperature changes faster for more efficient temperature control.
