Very low temp issue with a 2000 GP GTP. *solved*

Hey guys I just picked up this car today, and went for a cruise around town! It's about 65ish tonight. I drove her for around 2 hrs, used up about a 1/4 tank of fuel, and sadly never got over 60. The guy I bought it off of said to me that the temp doesn't usually warm up until about an hour after driving it. The heat wasn't melt your face, but it wasn't cool air blowing through the vents either. I'd say it was good enough to keep me comfortable.

My issue here is my gauge didn't appear to move up at all. During the day when I was driving to DMV, pick up kids, n food. The ambient temp was roughly 80 today. I did notice the temp gauge went up to maybe the first line after the absolute bottom. Is this an issue?

I searched for temp gauge issues but only found them to be about too high of temp, I seem to have quite the opposite! I also have very little car knowledge, but I want to learn!! This car is AWESOME!!

Car specs: 2000 GP GTP 98k miles.

Thanks for looking guys :)

T Stat might be stuck open. Replace with a stock or drop to 180* T-Stat since you live in a hot state.

I run a 180* T stat here in Louisiana/ Texas with no problems and after 10 minutes the heater will melt your face.

As for brand of T Stat, I went with a Never Fail and have your radiator cap tested also, I had a new cheap one fail, went with a Stant for the cap.

Edit: Scotty with the ninja, every time, your fast bro LOL.
 
Re: Very low temp issue with a 2000 GP GTP.

Is it bad to be running it like that? I'd like to drive it around until I can get it fixed, if at all possible.

Does not hurt it, but you will use way more fuel cause the car is trying to warm up, so it dumps more fuel to compensate, at least thats what I have been told.
 
Re: Very low temp issue with a 2000 GP GTP.

So that's probably a reason for the extra fuel consumption I presume, that or my foot.... lol!

I would say a combo of both HAHA, since your going to change the T Stat, might as well do a drain and fill of the coolant and make sure to use the bleeder screw on top of the T Stat housing to get all the air out.
 
Re: Very low temp issue with a 2000 GP GTP.

hes saying its a good time to flush the cooling system, not needed but cant hurt, i change all fluids when i buy a new used car. this way you have a new record.

yo can take the 2 bolts out lift the housing off, swap the t stat, re bolt it down with a new gasket. no real need to dump the coolant.
 


Re: Very low temp issue with a 2000 GP GTP.

Just got back from doing the home made intake install test run. Had to have a buddy put silicone on the sensor (hole was 'wallered' out a bit too much lol). Works and sounds amazing! Now to let it cool so I can check what the coolant is like. I'm hopefully going to replace the thermostat this coming sunday or even saturday. I bought a thermo from AutoZone, and I think it's rated at 190 degrees. I live in southern AZ so it get a chilly 115 in the summer. Should I take this back and order a 160 or 180 from an online place? Or should the 190 part be ok?
 
Re: Very low temp issue with a 2000 GP GTP.

190 is fine, never drop to a 160 and if you want, go with a 180. I have a 180 and have had no problems.
 
Re: Very low temp issue with a 2000 GP GTP.

Your welcome, throw on a Stant brand radiator cap to be safe also.

I went through two of these Murry caps in two weeks, they are worthless IMO MCS Murray Temperature Control 7816 - Safety Release Radiator Cap | O'Reilly Auto Parts

Then I got a Stant and have had no problems

Re: Very low temp issue with a 2000 GP GTP.

Sweet, I'll look into that as well! I'm only thorough page 5 of your GTP progress and son of a biscuit man... that thing is nice! I noticed you changed the SC oil. Do you think that's something I should look into doing as well? Like I said I have no clue at all about cars (I was nervous when I installed my custom 'open cone' lol). I'm 27 and a computer geek, but this car stuff is hella fun!
 


Re: Very low temp issue with a 2000 GP GTP.

honestly i'd change it to be safe but usually ever 40k or something like that is good.
 
Re: Very low temp issue with a 2000 GP GTP.

Well I found out that I'm pretty sure the guy has used just water in the cooling system. Am I screwed with this? I popped the cap to see what the color of the fluid was and it was clear. Reached my finger in and wiped the inside neck and there was black crap on my finger. Should I take this to get it professionally flushed? Or would I be able to use a garden hose to push the old out along with the nasty deposits then top off with any old brand 50/50?
