180 degree thermostat

bljseal · #1 06-25-2004, 01:29 PM

Does anyone know where to get a 180 degree thermostat for a 2003 Durango R/T??? The local part stores don't carry any thermostats and Summit Racing, JEGs, etc do not have one either.

did you checked the dealer, or check carquest.com

What? Your Durango should have one in it already. If it's busted then your dealer must carry it. Just ask for a thermostat for your Durango, I bet they even have it in stock. A 180 degree thermostat is normal for that vehicle.

Standard for the R/T is 195 degrees... in fact, almost all vehicles run 195 degress in order to meet federal emissions standards.

Turns out NAPA carries a 180 degree thermostat and I'm on my way to get one. Thanks.

Must be a states thing. Every vehicle I've ever seen here has a 180 degree thermostat in it.

Good to hear that you found one.

What advantages you get by dropping the stat 15 degrees?

Little bit better fuel economy, extended antifreeze life, it's a little bit easier on everything overall.

Will it affect emissions? Someone mentioned about that. I would love to run cooler, but hate to fight the state inspector if I barely pass inspection! Texas Inspections are very strict on the emissions control.

It shouldn't matter because they test when the engine is cold anyway don't they? An engine makes most emissions when it's cold.

A lower temp thermostat will increase emissions...exactly how much, I'm not sure. It's not that you get better combustion with the higher temp, but the cat works better with hotter exhaust gases. A cooler engine temp will prevent early detonation and overall less wear and tear on the engine components. You can always install a 180 degree thermostat and get your car inspected. Worst case is that you fail and have to reinstall a 195 degree thermostat and test again.

I have a 98 D SLT and may need a new thermostat. Is is hard to replace if done yourself? What type is right for a 98 D SLT??

Replacing the thermostat is a very easy DIY.

Where is the thermostat located for the replacement on a 98 Durango. Id like to get this replaced soon and how long would it take?? ...any tools needed?

It's usually in the goosneck fitting where the hose goes from the engine to the top of the radiator. No special tools needed.

You have to drain enough coolant to lower the level below the gooseneck fitting, otherwise it'll just spill out when you disconnect the hose and unbolt the gooseneck. Just drain it into a bucket and reuse it when you've finished the job. When you pour it back into the system, strain it through a clean rag to trap any debris.
