Default cold weather problem...

the other day i was driving to school. after i got off the interstate i was stopped at a red light and just happened to look down at the temp gauge. it was dropping! it slowly kept falling until i started moving again. it got down at least 25 or 30 degrees while idling there. it wasnt long before the temp was back to normal once i started driving again. is this a problem? or just a normal thing? recently it has happened a couple times but only when its around freezing temps outside or colder.

i checked the coolant level and its fine- i have never had a leak or anything that i know of. and the truck has never run hot and i always keep an eye on the gauge (just a habbit)

i wouldnt be too concerned as of yet, but i'd keep an eye on it..

If it becomes an issue, i'd replace the thermostat (cheap and easy fix) then see what it does. Sounds like its sticking.

does it sound like the cooling fan is stuck on? basically does it sound like an airplane under the hood lol

If its not low/loosing coolant it is either a stuck thermostat or maybe a fan clutch.

It would be impossible for a stuck fan clutch to cause this. By design, the t-stat would close once the temperature got down to about 180 and cease flowing coolant through the radiator.

Definitely sounds like a t-stat stuck open.

ill check into it but i just wanna say that it warms up pretty fast, and i drive easy when the engine is cold.

stupid question: is the thermostat located under the top radiator hose on the engine? i am not very familiar with modern engines. thanks

yes it its located under the top radiator hose on the engine. just pull it out and make sure you get a new rubber seal with the new thermostat and then just drop the new one in. you might want to put an oil pan or something under the engine to catch any loose engine coolant

new thermostat seemed to fix the problem. the only one that advance auto had was 3 degrees hotter. so the temp gauge reads the slightest bit higher once its warmed up. it shouldnt be a problem right?

The hotter temp won't be a problem and might even help with efficiency!
