Silverado Sierra Thermostat Replacement 160° (2014-2018)

[@harbieid8350]

I’ve suffered from this issue for about 2 months and all maintenance specials they admitted that this unusual and we have no idea about it. This video make my day and I cannot wait to adjust the temp. I’ll update once I make it Thank you for sharing this information.

[@SilverDollarSaloon]

I changed my water thermostat to a 180 degree and added a very large engine oil cooler.My 2015 silverado runs cool at this setup.I live in Florida,so I do not run the heater much.Also added the auto transmission oil cool solutions kit which keeps the trans oil 30 degrees cooler.Awesome modifications.

You say in description that your putting in a 160 degree thermostat, but the part number you listed to get it from Amazon says 180 Can you tell me the right part number to the 160 degree part?

Does it still work if you don’t change the settings ? My truck started heating up when towing and I’m under tow weight

[@TheJcrandazzo]

Modern day engines are designed to run hotter for better fuel economy and minimizing carbon build up.A cooler running engine may initiate less efficiency and problems over time .Good mechanical video..Thx

I didn’t even have to go through all that. It took me only a hour and a half to change thermostat and Cooling Temperature Sensor. I just only had to replace a gallon of antifreeze without even having to drain it.

Where does the small hose off of the housing go to?

[@southparklimo]

Why would the dealer want to replace the water pump housing with the thermostat because of a low coolant temp code. No loss of coolant, just a 'check engine' light coming on at times and the radiator fan runs after the key is turned off.

[@abrady487]

So I replace both the sensor and thermostat and the damns fans still coming on. Thoughts anyone?

[@rhasheedharrison9547]

Will this thermostat work properly if you dont tune it afterwards? How long can you drive your truck before tuning?

[@AaronHinesAuto]

yes it will work properly and it wont harm anything. but the ecu's cooling strategy will be off and the fans wont be told to turn on at cooler temps. making changes to the tune only give you better control of the engine coolant temps to keep them down.

I didn't the link for the rubber gasket before you put on the thermostat in the description.

I noticed that the block didn't have a gasket. Mine did. I pulled it and tossed it. The new housing had that o-ring. I've been losing some coolant. Curious if that gasket was needed. Ive seen other videos where that block gasket was also tossed. I'll check the hose fitting, but was curious as to your thoughts on the gasket.

จิรพงษ้ ชั้น 2

[@KayJay940]

I always thought it was the spring which controlled when thermostat opened and closed. Can you please explain why this not the case. Is the one you put in slightly smaller or something so it opens at a lower temp? Hard to tell on video and no I'm not a pro just a diyer.

[@MikeOn2Wheels]

What opens the thermostat is the wax filled cylinder in the middle which when exposed to heat expands and pushes the valve open. I’m sure changing the volume or type of wax used is how they achieve varying temperature ranges. The springs job is usually to oppose the valve opening and close it as it cools or keep it closed until the force from the cylinder pushes it open.

[@KayJay940]

@@MikeOn2Wheels see I thought the spring just acted like a release valve when pressure was high enough it would push sping back/in and then when it got lower spring would close. This opening and closing would release hot coolant to the rad and allow cool coolant to rush in since it's a closed system.

[@MikeOn2Wheels]

@@KayJay940 coolant pressure would be roughly equal on both side of the thermostat in a closed system. Drop a thermostat in a pot of boiling water, it’s actually kinda cool to see how it opens and then closes again in a pot of cold water. It’s a good way to test a thermostat.

I have a 16 5.3. Started with the stock t sat. Truck would heat up to 210 and creep to the next hash to the right of it. Tried a 180 t stat and fans on early, I still stay above 210*F at idle and it’ll creep past it. Driving on the interstate and it’s at the tab to the right of the 210 mark sometimes more. Tried the oem stat with weep holes drilled in. No change but the coolant temp will drop in the rain or extreme cold. Put the 180 back in it. Same results again. Ordered a new temp sensor to try next. Would you have any recommendations?

Engines prefer to run cold. Colder the air the closer the molecules and the more air molecules you get in chamber. Basically in the winter everyone is running a CAI.

[@robertcohen5263]

I had my original thermostat start to stay open. It was running at about 180ish. One thing I did notice is in the winter, I didn't have the regular HOT heat. Replaces it with a new stock thermostat.

[@krisgilbert3415]

How do you get that program to tune the vehicle after? Do you work on other people's vehicles or have a shop somewhere?

[@Patrick_Gray]

I owned an automotive air conditioning and radiator shop from 1973 to 2002. When 195 degree thermostats first came out many people would change it to 180 degrees or even to 160 degrees. I thought the vehicles should be kept at design temperature so I did not. We did a lot to keep radiators clean inside and outside. We upgraded to larger radiators and cooling fans to increase cooling capacity (not normal operating temperature). We had a radiator flow tester to test radiators and rodded or replaced them if needed and did are part to keep engines at proper temperatures. My question is why you changed all the way to 160 degrees. When the car is sitting still or is in slow traffic the radiator fan setting will probably control the coolant temperature. But when cruising at say 50 MPH it would seem the coolant temperature would be a few degrees over 160 degrees (start of thermostat to open). So there would be a wide gap of operating temperatures.

[@villagomezjaime96]

do you know of any upgrade cooling fans for a 2018 5.3? My engine has 40k miles and it likes to warm up a bit past the 210 mark? .. or any tips to keep it cooler? Id appreciate it alot

[@tunerguy95]

@@villagomezjaime96 you want it right there. That’s where it’s designed to run. 210 or a little abound is good. Any less and your mpg will drop. The truck will be more responsive at a lower temp thermostat that’s the only pro

[@pokerstar81]

I noticed they sell a 195 oem style for the 2015 silverado I'm swapping the radiator so was going to put one in but it's twice as the stock temp one.

[@ericr530]

I'm certain your level of expertise is leaps and bounds greater that mine but I do own this type of vehicle in the video and unless you are towing heavy loads frequently in desert heat, (probably less than 1% of GM truck owners, most folks that do this under these conditions use much heavier duty 2500 and 3500 series trucks anyway) there is no concievable reason to deviate from the GM spec thermostat for this engine which is 207F. Fuel mileage will degrade also and be noticably less using cooler than 207F spec thermostats as well.

No stuck open should cause your engine to run cool. Stuck closed would cause your engine to overheat and could cause some damage.

Well to let all Chevrolet Silverado owner’s know, replace both the pressure sensor and the thermostat. Save them the headache of changing on and going back to change the other. Do both!⬆️🆙

[@ericr530]

Unecessary. "If it ain't broke, don't fix it". If you're referring to the "coolant temp sensor" I'm not sure what you mean by the "pressure sensor" I just replaced the thermostat on my 2016 LT 5.3 today. Was just the thermostat, running at normal 207-210F now after replacement. Coolant temp sensor works fine, otherwise temp gauge with new thermostat would not read proper operating temp. Getting the genuine GM AC/Delco part was a mother. Local O'Reileys, Advance, and Autozone said no, RockAuto no go either. Finally found one online after digging. Local GM dealer charges $500 and some change for this stupidly easy fix. With that OEM part hard as heck to find and GM dealers charging a mint for this repair I smell a racket. Count me out, won and done.

I know because I have been running a 160 Powerstat from Hypertech with Hypertech tune for almost 20 years now with zero issues. A 160 with tune can actually make you way more power because engines like cooler dense air. But also a 160 will imrpove reliabilty, fuel mileage and the life of your engine. Anyone who tells you different has never used one to know the difference. Like I already said. I have been running a 160 for nearly 20 years now which is enough time to experince the clear difference.
