Your thermostat may be defective. It controls water flow and temperature and it cost $8-10.00. Good Luck!!

Why do my temperture gauge rise when im idle and drop when im moving 2002 Infiniti qx4


Hi Delevain:
This is a fairly normal circumstance.
When you are moving, there is an increased flow of air through the radiator. That cools the fluid, and thus the lower temp indication.
When you are stopped, there is very little air flow through the radiator (just from the fan) which results in the engine being able to heat the fluid faster than it can cool in the radiator. And the temperature increases.
As long as the temp does not increase to the point where daage could occur, all should be good.
Cheers.

What cause lower radiator hose to collapse after cool down


Hi Larry:
Good observation. Not too many people would spot that.
When the engine is hot, the coolant is hot and expands. At the filler cap for the radiator, there will be a hose that goes to the overflow tank. As the coolant fluid expands, it flows through thie tube into the overflow tank.
When the engine is turned off, as it cools, the volume of coolant in the engine and radiator contracts, and is supposed to suck fluid back from the overflow tank.
I'm suspicious that something is preventing this from happening so the vacuum in the engine coolant system is collapsing the hose.
WHAT TO DO?
- Check the radiator cap. Make sure it is functioning correctly. Make sure that it is correctly installed and screwed all the way on.
- Check the coolant overflow hose. Make sure it is not plugged.
Odds are that you will find the problem quite quickly.
Cheerfuls.

Hello... I got problem with my honda odyssey. For the past 3 days, if i start the engine, after 5 min the temperature will goes up to HOT and engine indicator light-up. I turn-off the engine and then start...


Your English is very good.

From what you have described, which is a rapid over heating of the radiator coolant fluid and therefore a hot engine condition, it would appear that the thermostat in the engine's cooling system is faulty.

If the thermostat is sticking in the closed or nearly closed position temporarily, there will be no flow or very little coolant flow between the engine and the radiator and the engine will overheat.

You have advised that after the engine is shut off , and radiator coolant fluid has cooled, you re-start the engine and drive the car without the overheating condition occurring again and the radiator coolant temperature is normal. This time there is no overheating because the thermostat is working normally.

You should have the thermostat replaced as soon as possible because allowing the engine to overheat can cause very expensive engine damage.

If you had a continuing overheating condition then I would suspect both the thermostat and the water pump. However as the overheating seems to be only temporary, and clears itself after you have shut down the engine and re-started it 10 minutes later (without further overheating arising) then I think you only have a faulty thermostat.

Please also check that the electric fans which draw air through the radiator are operating. These run on a temperature sensor and will switch on automatically once the radiator coolant fluid reaches a certain temperature and then switch off again when the fluid temperature reduces. You will hear them running once they start up. If these fans are not working the radiator coolant can quickly overheat in various driving and temperature conditions because there will be insufficient air flow through the radiator to cool the fluid. If the temperature sensor is faulty or has died, or if the electric motors running the fans are faulty, the fans will not operate.

I hope this helps.

Can I still drive my 1994 toyota corolla if I need to replace the radiator?


You can chance moving it in your driveway very quickly if absolutely necessary (I don't advise this), but I wouldn't push it further than that. The purpose of the radiator is to cool the water that flows through the engine, keeping the engine from over heating. If your radiator blew and all of your fluid is out of the system, it can no longer keep the engine cool. Once it overheats, you risk blowing the head gasket, warping the head or completely ruining the engine altogether. With no fluid to keep it cool, this can happen very fast.

Hope this helps!

How do i put water for the radiator?


Does your car have a cap or a sealed unit? You don't want a sealed unit. You want to be able to check your water.Push down and Twist the cap off when cold, not hot, fill it up with coolant, 50/50 mix, and fill up the expansion tank. It says coolant on it. The car will balance itself out. Check the water in your battery while you are at it. It dries out too. Then check the brake fluid, power steering fluid, and oil. That should keep you busy next Saturday. Hope this helps.

the coolant should flow from the radiator into the reervoir as it heats up. When it cools, the fluid flows back into radiator.
Check to be sure your cooling fan is coming on when the engine gets fully warmed up, and when you urn the a/c on.

When you bypass the heater core the path for the water to go through the core is gone. Correct?, you have connected to engine water line out to the engine water input? thus bypassing the heater core........


No, you just won't have water flow through the heater core, Coolant flows through the engine through the lower radiator hose as the water pump sucks it out of the radiator and pushes it through the engine. It then flows out the top radiator hose when the thermostat opens. It then flows into the radiator to cool off.

Is your heater core leaking?

Hi,

Lot of possible reasons. Some of them very stupid, even though I mention it here, sorry:

1. Thermostat regulating the cooling fluid flow - works correct?
2. Enough cooling fluid? Not leaking from somewhere?
3. Level of engine oil? Its quality? (If dirty or low oil, heat can not spreed into oil - oil is cooling subsatnce as well. If low oil level - you know what, engine is not lubricated etc.)
4. Water pump works correct? No pump, no water circulation.
5. Any dirt in the water circulation system? Piece of rock, shred of rag, maybe some sediments (can figure out only after disassembling the system = lot of garage work).

I had one friend who complained about his mazda MX3 quick overheating. My first question was, if there is cooling fluid and he told me "Of course!!! - I was in the garage yeasterday evening and fluid was refilled." The engine was hot and smoking badly after 3 mins of calm slow ride. Next day he called me with curious finding - there was no cooling fluid at all, was leaking out from the radiator. Thanks for contacting Fixya.
