Question about 2002 Toyota Celica

Coolant level rapidly falling and heaters blowing cold air

I have a 52 reg Celica VVTI, the other day i noticed the fans blowing stone cold air even though engine temperature was just below the middle of the gauge (even when driving it has never gone above this point) and all fan settings were on HOT but yet it still blows cold air. When accelerating the air coming from the fans instantly goes hot but temperature seems to drop again when in accelerator is depressed or cruising in 5th or 6th gear. Also not sure if this is related but i noticed that the coolant level has dropped dramatically. I filled the coolant in the resevoir up to max yesterday and went for a drive, i checked again today and coolant was empty any ideas on what could fix this or even if the two issues are related and what has caused it? As far as i can tell there is no white smoke coming from the exhaust (except on really cold days) Any help will be greatly appreciated as i only bought this car 3 days ago. Cheers

You need to get a cool STANT (or similar) pressure
tester... find your LEAK... and fix it... FIRST.

Anything else is just wasting your time!

One of the best investments I ever made.

SOURCE: Frequently loss the coolant and

You are losing coolant if you have a coolant pressure tester follow the directions and use it. If you don't when the car is cool use a 50/50 solutuion of water and coolant fill system and check all the listed items carefully with a flash light and look for leaks. It is either a bad hose, cap, water pump or radiator. Your coolant circulates through the dash and the blower blows throught the heater core to produce heat. No coolant no heat. I would also check the passanger side floor for anti freeze or moisture could be a leaking heater core also.

SOURCE: 2000 Toyota Celica coolant reservior empty

I hate to tell you this but its possible...

You have a leak. Look around on the driveway and try to determine if you have an external leak as opposed to an internal leak. If you see no coolant on the ground, suspect a blown head gasket. Do not continue to drive this car in this condition. If it does indeed have a blown head gasket, serious engine damage will occur.

Check your exhaust for white smoke. Chances are good you have a blown head gasket and coolant is leaking into the engines combustion chambers and is essentially burning off. Also check your oil, if it looks like caf mocha, this will confirm coolant is leaking into the oil via the blown head gasket

SOURCE: Intermitant temperature

Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.

SOURCE: coolant system

If your coolant level is dropping, I would suggest that you take a good look at the water pump. That is a very common coolant leakage probelm area on your vehicle. I change 2-3 a week.
Hope this helps.

SOURCE: My car heater is blowing cold air

The shut off valve on the heater core was left shut during the repair on your coolant system. the repairman forgot to re open the shut off valve . this is the problem. open the shut off valve and, the air will become hot again. as for the gauge fluctuations, the actual gauge may be malfunctioning.

Is there a fuse or relay for the heater in my 2002 ford expedition


No hot air is due to low coolant, or even poor coolant flow. The engine heats up the coolant, and it passed through your heater core, and the heater blower motor pushes air through the heater core to warm up the air. If your "fan"is working, but the air is cold, make sure your coolant level is good.

My heater does not blow hot air and my engine fan stays on all the time


It sounds to me like you are low on coolant. Check the level in the overflow bottle and fill it up. If the heater blows cold air you are looking at close to a gallon to top it up. Once it's full, then leave the cap on loosely, so air can blow out and keep it topped up, for a day or two until the coolant level stops going down, then tighten the cap. Hope this helps.

I have written a tip on this.
You may have a couple of problems. I would first replace the thermostat, and make sure you have the proper coolant(ant-freeze) level.
Please let me know how it goes and if you need further help I am here.

2004 toyota celica will not blow hot air for twenty minutes


If the engine temprature does not reach the normal level as it used to, it may be the coolant thermostat.

Iif it does, it could be air diverter gates not working properly, cold air blowing at a a light could point to that. The diverter gates are located under the dash.

It also coul be the valuve that controls the water to the heater core, but unlikely cause of the cold air at a light.

Would the heater control valve malfunctioning make the engine overheat blowing hot air out the heater one moment,then not blowing the hot air, temp gage spikes 225 plus. The motor takes awhile to heat up...


Heater control valve malfunction will not cause engine to overheat unless coolant is leaking externally...Overheating going down the road can be the result of a few different things...Partly clogged radiator...Insufficient air flow due to possible fan problem...External coolant leak...Make sure fans are operting properly and have cooling system pressure tested for leaks...Gaining and losing heat on the inside of the vehicle usually means system is low on coolant but you must find out where coolant is going

Blowing cold air via the heater


Assuming that none of the Electrical/Electronic controls were disturbed when changing the Thermostat it seems to me that you have an "Air Lock" within the heater. One must purge all the air out of the cooling system as close to the highest point as possible after the system has been partially or fully drained. Most of the time one will find small BRASS Bleeder Valves located somewhere near the highest point. Open each one while the system is pressurized and let Air escape until some Coolant escapes. Sometimes it may be necessary to loosen a Heater Hose and bleed the air at that point. Remember that the system MUST BE PRESSURIZED to accomplish the Bleeding of Air. Many auto parts stores sell hand pumps with a pressure gauge for this purpose and leak testing. These pumps typically replace the Radiator Pressure Cap temporarily. The system does not have to be at normal operating temperature to bleed the air out. Once the Air has been bled you will have to refill the radiator to normal full and make sure that the Coolant Recovery Tank level is also brought up to recommended level. A quick check is to remove the Radiator Pressure Cap, Start the Engine, Rev the engine suddenly (A short Jab) and see if the coolant level falls rapidly in the radiator. If it does it is definitely an AIR LOCK situation.

Engine overheats when heater pipes connected


I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.
