Re: Overheating Problem in Maruti 800

Hi all,

From 2 days I am facing the same issue, the fan is running, but after I drive 15 - 20 kms and switch off the engine I am able to hear the boiling sound , When I checked the sound is from the coolant tank the water/coolant was boiling the box cap has changed its shape, but the gauge shows only half the way.. pls help, my car is 8 years old and clocked 74500 kms, I got the coolant replaced recently..

Hi Varun,

Coolant boils when there is a leak in the coolant system and the excessive pressure increase is sending the hot coolant back into your coolant box before blowing off any of the hose pipes and engine seals.

You will also notice that your AC will get get cut-off when the engine is very hot.

I would advise you to do this.

On a cold engine -

1. Carefully open the radiator cap (Be very careful)
2. Start the car and let it warm up. Do not accelerate.
3. As the car warms up, you may see that the coolant visible in the radiator will keep going low. This is because, your coolant levels are really low in the coolant system even though you topped your coolant box.
4. Now slowly give throttle to teh engine and you will see the coolant level further decrease from teh radiator cap.
5. Keep 2-3 bottles of coolant aside and keep topping up.
6. Keep doing this exercise of throttling that way you can really fill the radiator with coolant.
7.Once your radiator is really full, top up the coolant box too and close the radiator cap.

This should fix the problem.

Let me know how it goes.

Thanks , I just topped up the coolant in the reserve tank as it was fully diluted (brownish green colour), and almost empty, I did this when the engine was hot, now after 4-5 hours I noticed the coolant level has gone to empty, though no leakages, I guess radiator was fully empty..should I top up or leave it .. ?

Re: Overheating Problem in Maruti 800

So I was spot on, your coolant levels are way low in the coolant system.
Please Follow the steps I mentioned.

How ever try to flush the coolant box first and do a fresh refill of the radiator using the throttle method.

Hope this helps

Make sure your engine is cold and careful while you open the radiator cap

wot will be the reason for coolant fluid not coming to the radiator even when the engine is cold???

Re: Overheating Problem in Maruti 800

Its only a safety precaution.When the engine's hot, you are never advised to open the radiator cap (its embossed on the cap too). The coolant liquid might spray out if not careful.

Hope This Helps

Re: Overheating Problem in Maruti 800

Thanks for your support, I just removed the coolant tank and cleaned it up fully as it was muddy, now topped up. Should i dilute with water/distilled water with the coolant..or only coolant should be used ..

Re: Overheating Problem in Maruti 800

yeah i know that, my query is

your coolant levels are really low in the coolant system even though you topped your coolant box.

on cold engine, coolant fluid will be flowed to the radiator, why the need to top up the radiator directly

Thank you, I have filled the coolant box now, let me see the result today..

Re: Overheating Problem in Maruti 800

What about the radiator ?
Did you top it up using the throttle method I mentioned yesterday ?

Good luck and keep us posted buddy.

Ya I followed the same method, now the boiling problem has solved, still I am feeling its getting heated than the normal, now the coolant stays full in the reservoir(box)..
