so the last few days my car has been running really hot and wanting to overheat...only thing that i can do to keep this from happening is to turn the heat on full blast in the floor, and the temp will go back to normal...otherwise it'll just get hotter and hotter.....any ideas??

start with the thermostat and check the coolant level

thermostat is less than a year old so i don't think its that, but i guess its possible, and coolant level was fine.

oh it can still be it, i have had them go bad in days, or just be bad when i have got them. make sure there is no air pockets in the system.

+1 they are foreign made pieces of shit. throw it in a pot of water on the stove and watch to see if it opens

and the thing that he said about the heat making it cool makes me think its forcing it to cycle faster there for avoiding the air pocket sitting in one place? sounds like it could be it to me.

Which degree thermostat do you guys go with?

fan clutch??
I had the same problem and it was my fan clutch...if you can turn/spin your fan by hand and there is not much resistance then you need a new one

but would that make a difference with him putting the heat on full blast and making it cool down?

I've stopped buying the cheapest ones because 2 of the last 3 were bad out of the box. I have no proof the slightly more expensive ones are any better quality but worth it to me for only $4 more.

For the temp, I use 185 or 192/195, whichever I feel like buying at the time

Placing the heat on high uses the heater core in the car to remove heat from the coolant the same way the radiator does, it is just like adding an additional small radiator.

i really don't care much for NAPA but they have better quality parts sometimes.

It did for me...I did that exact same thing too and blasted the heat for a while until I figured out what it was

i see well this is why i am glad i signed up here, i been just gettin on on these topics to learn more about the mustang. i have had one about a year ago for 8 months and sold it, but now going to get a nicer one so wanna know everything i can!

[Traidmarx]

i have a 180* thermostat in it, i dunno if i go through the trouble to take it out and test it i'll spend the extra 10 bucks and just put a new one in...i just thought it was weird that it cools right down when i turn the heat on in the floor, which i know causes the car to cycle coolant through the heater core.

Believe me...I am no expert on engines and the only reason I know it might be the fan clutch is because like I said...my car did the same thing and I also blasted the heat and once I changed the fan clutch it solved the issue.

My take on the subject is that blasting the heater will take heat away from the engine no matter what and then you just have to pinpoint why the car is over heating
