engine running very low
Hey guys,I need some help...
My girlfriend just bought a 00 integra gs and she's having some problems with her temp. Gauge...when she let's it idle and warm up it goes up to a little below normal temp. But as soon as she hits the gas and starts to accelerate the needle goes all the way down to cold, it doesn't go back up until she let's the car sit and idle, another symptom is when she turns the heat on it only blasts luke warm at best, never hot. I think it may just be an issue with her thermostat and that's a cheap 15 dollar fix but I'm not positive...
Thanks in advance for all of your help!!Would like to get this issue fixed saturday!

Re: engine running very low
Sounds like a thermostat stuck open. I found a screw in the thermostat of a civic.
Yes, it will stay cold and not blow warm air for a long time if it is stuck open. Easy fix.

REMOVAL & INSTALLATION
1. Disconnect the negative battery cable.
2. Drain the cooling system into a suitable container.
3. Locate the thermostat housing by following the upper radiator hose to the engine.
4. Loosen the hose clamps then carefully detach the hose from the fitting.
If the hose is stuck, carefully use a pick to break the seal between the radiator hose and the housing. If the hose is deteriorated, replace it with a new one.
5. Disconnect any sensors or switches that may interfere with the removal of the thermostat from the housing.

6. Unfasten the retainers, then remove the thermostat housing.
Some coolant may leak out of the housing as the seal is broken.
7. Remove the thermostat carefully noting how it's installed.
8. Clean the mating surfaces of the thermostat housing.
Many thermostat housing's are made out of aluminum alloy. A plastic scraper is very effective and will not harm such metals.
To install:
See Figures 4 and 5

9. Install the new thermostat and gasket.
Install the thermostat with the jiggle pin facing up. This acts as an air bleed and must be at the top of the thermostat to operate properly.
10. Install the thermostat housing, then tighten the bolts securely.
11. Connect the radiator hose and tighten the hose clamps securely.
12. Install any remaining components, then refill the cooling system.
13. Start and run the engine until it reaches normal operating temperature while checking for leaks.
