Default Temperature is low

hi all

my integra has been running fine but since it started to get cold out the temp gauge is almost always on cold even when driving at high speeds on the high way. the only way the gauge reads it is warm is if i let the car idle for a good 5 mins after driving around for a bit. once it reads warm as soon as i hit the road the meter starts to dip and usually within a minute or 2 it is back to freezing cold unless i idle for a good few mins.

i think it has something to do with my thermostat or maybe my cold air intake. i have a simple ractive cone for the intake and no access to the stock box air filter thing. maybe the thermostat is in a bad position like its cooling off and catching cold air as i drive where is the stat supposed to be located exactly does anyone else experience this?

im posting pics to clarify better u can see from start up to warm up to driving again

hahahahaha omg you guys are dumb no offense at all.

You thermoSTAT is busted. just grab one from partsource or somewhere, get on thats like 180 degrees or 170 those are both like stock and replace it. it on the lower rad hose right against the block. that will fix everything.

Dont call people dumb just because they dont know too much about cars. Simply induldge them in what you know to help then grasp a common sence on cars. Not all of us are mechanics. Im im school for law, if I ask you somthing about the act 4.6 bar in the 1980s, will you know?

Were all on this forum to learn things and communicate. Not put peoples self-esteem down by calling them dumb.

All he's trying to say, is that it's hard not to be taken offensively when it's an attack on intelligence. Especially when it's over the net, it's all too easy to take anything the wrong way.

It's Christmas guys, lets not do this.

I agree with XNXIXTXRXOX. i sort of stopped responding to some threads because some questions are just....silly and people who respond are even more silly. haha
OP-you will need a new thermostat.
all others, if you do not know, dont guess hoping that you get it right. you will cost the OP money. Obviously by saying "thermomiter" you do not come across too bright. no offence, but if you do not know what is going on then stfu.
Also Anthony, if you wanna talk about law, start a TorontoLawClub, this is about cars so if you do not know all that much and trying to learn, dont suggest anything and stick with lurking.

It might not be the thermostat. You cant listen to people on here. Nobody is that good at disgnosing a problem just from you describing it. Check with a mechanic to be safe.

well i had the same problem and it was the thermostat. its staying open. when your car is sitting, there is no air flow over the rad or motor, allowing it to heat up. with the thermostat stuck open, when you drive, the motor gets cooled too much when a good working one would close and allow running temp to remain steady. its a very simple thing. and theres no thermometer in a car, thats for when your sick. theres a temperature sensor lol, which either works, or doesnt. it wouldnt cause temperature fluctuation. it just wouldnt read the temp at all.

and lol he did check with a mechanic... me. notice he said it only happened when it got cold. ALWAYS a thermostat when that situation occurs. typical of our cars with mechanic thermostats that have been in there for like 15 plus years lol.

its not that bad, but deff not good. it will run richer, not allow oil to reach a peak temp, and just not let your motor run as effiecent as possible. better to fix it. i did mine, 18 buck for the thermostat and no money for coolant cus i just used shoip stuff. but still, cheap easy and simple.

you know what guys i think i ran into to the same problem
and this started ever i got my oil change
everytime my car is indle i see it warming up
but if i take it on a highway it keeps telling me its low temperature just like the other guy said..
so i guess imma have to change the thermostat too
but i took at the pictures of this guy that started this thread and mine is a lil different because his goes below the cold line, mine stays right on it but also keep in mind its winter and i have heat in the car most of the time.. and i know heat makes your engine cool down a bit
oh ya and i also noticed it starting once the temperature outside got colder in the summer it was working fine

feedback needed please..

I actually have a somewhat similar problem with my car, but it's not as bad - the temperature stays below what you'd expect when the car's running, just under the 1/3 mark. Especially when cruising in 5th

is it the coolant temperature sensor or the coolant temperature sender

maybe i should buy both

also i dunno if i should order these parts for the b18 or the b20 im pretty sure they r interchangeable anyways

im gonna try the thermostat first after reading XNXIXTXRXOX's response he makes a good point that if it was the sensor it wouldnt read temp at all hopefully its nice out 2moro and i get it done ill post if i am successful

i think my car is developing the same problem
it is taking long to 'warm up'.
even after a good 15-20 mins of driving, the needle is only at 1/4
is the 'thermostat' an easy DIY?

i checked my coolant level and its filled up to the top

if it struggles to heat up it could be either thermostat or you could just use a coolant flush.
thermostat is a cheap and quick fix. you will drain out a lot of coolant so might aswell open the rad and get all of it out and replace with fresh one.
if thermostat is stuck open, you will NOT get hot air in the car. may get warm'ish but will not be hot.

if anybody wants their thermostat replaced, you can pm me, ill do it for you for some beer lol.

okay just wanted to give you pros are update
i was just driving my car and this time i didnt put on the heat
i noticed when i drove around 40-50 km/hour my temperature was slowly increasing once my engine got warm
as soon as i start driving constantly around 60 km/h or more it started going down to low again... i put on the heat and it was pretty warm on the first option

so do you guys agree that its not the thermostat.. very likely its just the sensor
or do you guys think i should change the thermostat anyway

im not a technical car guy so i dont know what to do

k..... this is lame. the sensor just detects heat. has nothing to do with it the engine heating up or cooling down, unless its the summer and the fan kicks in. its a SENSOR ie a device which SENSES. the problem is your thermostat. just put a new one in and you'll be fine.

a thermostat controls the flow of coolant. your water pump is always moving coolant throughout the motor. when the thermostat is closed, it stops the flow of coolant and allows the engine to retain and build up heat. if it stays open, the cold coolant at start up will continually be in flow and constantly cooled by the rad, making it very difficult to build heat. the reaso it builds a lil heat going slow, is because there is less flow over the rad OBV. same as when you just sit and idle.

all in all its your thermostat. just replace it. its the easiest thing you can do. and cheapest.
