yup...another heating problem

Back In Octoberish I could warm up my car drive 15 minutes to work and the car would be blowing its normal scorchin heat.

today I get lukewarm heat after letting the car idle for 20 minutes..drive to work and still have a pretty cold car when I got there.....
This is just an example that I am using. There is something not right...
Air blows out the vent that is warm...not cold...but not like it used to be by far.
I have read numerous posts and I am thinking that it is the core everyone is talking about...Should I try changing this first and see if that changes anything? Im not a mechanic but can at least change my own oil....so is this something i can do alone...I saw
how to in that guys maunal lookup thinggy and it looks pretty simple....
Is there anything else that I should check aside from this and the hoses being hot test.? Also I had heard that if you are lacking heat it means that the transmission could be getting old ( ready to go) ...is this myth true?

what does the temp gauge read? if the temp is good, the vents in the air box may not be moving enough to let the heat through. if the temp gauge is low, the thermostat may be stuck in the open position.

temp guage

The temp guage is the one on your instrumet cluster maybe next to the fuel guage.

If you don't have a temperature gauge in your dash, you have a warning light that will come on if it gets too hot. If you don't have a gauge, let the engine cool completely. Start the car and keep feeling the upper radiator hose every 30 seconds. The hose should stay cold as the engine warms up and then turn hot quickly. If the temp comes up slow instead of quick, then the thermostat is probably stuck open.

Flush the cooling system and replace the stat. Should be good to go.

so if the thermostat is stuck open .....can it be as easy as "unstucking" it......or would this need replacement?

As far as the flush the coolant...this has been flushed and filled
a few months ago.....need it still be done?

Do as Joe F said, flush the system and replace the thermostat. You cannot repair a thermostat.

your parts house should list a stock replacement part. a different one may mess with the computer and how the engine preforms.

Correct. Go to the parts store and tell them, "I want the OEM temperature replacement. That is, the same temperature as the original".

Stant and other catalogs have a listing for the OEM temperature one and other temps available too. Go with the OEM one.
