Thermostat problem??

[Dubber]

Hello!!
So - my car recently has been taking nearly 20-25 min to warm entirely up.
It used to take nearly three min...
what are common causes of that?? thermostat??
heater is not very hot either, although its never really been that hot..

any ideas?

Yeah sounds like thermo. They stay closed until the coolant in the engine warms up, and then they open, allowing hot coolant in the heater core, and BAM!! Heat!! I have the same thing going on my SIlverado, but I am still looking for the chance to change it. I even have the thermo and coolant!

relatively cheap & easy fix?
what should i expect to pay as i am looking around today for it...
thanks a lot =)

dos the engine temp get hot but no heat?
if so then yes thermostat or water pump for the extrem case hoppfully it is only a thermostat
good luck and i would just order the parts and do it your self it is easy

the engine temp will get hot, but it takes nearly 30 min, the heater air blowing out will be lukewarm
very different from even last week =)
Still thermostat? worthy of just at least trying it im assuming?

Yes... Sounds like thermostat. If you have a VR6 its a couple hose clamps and 3 bolts to remove it.

no his car is a 1.8t or a 2.0t and were the thermostat is on thoughs but i am shur it is not to bad to do it is worth doing your self
and i would say yes it is the thermostat now with the new info should only cost like 50$ at most with coolent

Yea its a 1.8t
so if its not too difficult to remove to that, ill think ill try to do it myself !!

i looked around for a really good tutorial, ive only found ok ones so far - anyone know where a good one would be??

Yeah, I would do it youself. I am not sure where the thermo is located on the Ts, but on an old school 1.8 it takes like 5 minutes to do, you just have to watch out for the coolant shower!
