Engine Overheating for no obvious reason

[Xulfiqar]

drinking water is not distilled water. If you drank a bottle of distilled water it will screw you up.

who told you that?? distilled water is the purest form of water hence it has ZERO taste, natural drinking water (river/well etc) have dissolved minerals in them for taste. You can gulp a glass of distilled water no problem, it will taste a little strange to you because for you "normal" is not distilled.

btw the words "Mineral Water" are not allowed to be used anywhere in Pakistan, that is why all bottled water now say "drinking water" which is actually 0TDS, some expensive brands add a "taster" to it.

nobody told me.

I'm not referring to taste. It will be the least of your concerns if your everyday 250ml Nestle bottle was distilled water.

I am still unable to get any mechanic here. But i have observed one more thing that there were tiny bubbles coming in radiator from downwards. These were coming on and off, i mean to say they were not constant.

[sarmadraheem]

Got the car to the mechanic. He is of the view that gasket needs to be changed. He is saying this due to bubbles in the radiator. What should i do now?

sir i guess bottled drinking water (Nestle, Aquafina etc) is most of the time MINERAL water NOT distilled water...mineral water has mineral/salts mixed in it which is good for human health but very bad for radiator/car battery....distilled water on the other hand is pure water, which is WITHOUT any salts and minerals in it...distilled water is obtained from boiling water into steam vapors (only pure water will vaporize while the salts and mineral will be left behind) the steam is then allowed to cool down back into water in a separate container...hence u get pure water or Distilled water...
now obviously i dont want the poster or anyone else to put on a white gown and go into Alchemist's laboratory and do this but i just wanted to clarify the difference between the two which most people mistakenly consider the same, and happily pour 1.5 litr Nestle in their radiator coolant mixture thinking that they are using distilled water

I think article 63-A of Constitution of Pakistan FIT fine to all those who do not have any idea of distilled water & bottled drinking water.

bubbles could be because of some air in the cooling system. if water boils out on the acceleration even at cold engine then gaskit is damaged

relax OK. a suzuki bolan thermostat will fit Good in the engine, TRUST ME that you can source from 3S suzuki shop in RYK which is not far, take a dent in Mp'mthlo change the gaskit flush the radiator whatever best coolant is available mix it 50 - 50 with bottled water, ensure the fan is connected to actuator for auto function.

sir...all i said was with good intention...i didnt intend any pun..

How about 63-1(g) ?

bubbles can be due to a very dirty radiator. Happened with me once as well.

Get radiator cleaned up from the inside. Preferably get it changed (if you want to upgrade it as well). And use quality coolant.

Friends help me again. Did the worst mistake in my life i.e gave my car for gasket change in a small city and got the engine ruined. Mechanic made 3 attempts on gasket change. At first two attempts he got the new gasket, got the head surface polished and the result was jumping coolant from radiator on start up. Third time he checked the head himself when it came from the lathe machine. This time it was fine till we tested the car on AC for a few kms in city. After few Kms needle crossed half mark and there was jumping coolant again. Mechanic gave the verdict to change the radiator. Radiator was changed to double nali kabli one. Now, there is no boiling or jumping of water but needle doesn't comes below half even i drove the car from RYK to sadiq abad on N-5 for about 30 Kms. Another thing i observed is that at half needle when i turn the car off and restart it, it cranks as if there is low battery or self starter motor jammed. pleaseeeeeeee help i have ruined my precious car and so so much worried about it. please note that i have put thermostat valve in it and fan is direct.

[sarmadraheem]

One more thing i forgot to mention is that all the 16 valves are also changed. one of them was cracked.

[Sheryar]

Bro I think there is a air lock in engine
wht u do is
start car leave for five mins
open radiator cap check water level if down fill it up the close it
do same thing 5 to 10 times
until the water level comes up to one level ..
secondly do not fill the radiator water bottle full .. Keep it to max level ..
try this & share wht r the results ..

[sarmadraheem]

i will surely do this tomorrow

[Xulfiqar]

with correct genuine thermostat in place the coolant will become hot and the system will pressurize to 14 psi, anything above that will be expelled to the expansion tank, The automatic fan switch should be cycling the fan on and off at normal temperature, If your system is thowing out high pressure coolant into the expansion tank right after startup your head gasket or head is bad, why did you need to change all valves when only one was bad?

[ahsanonline]

the thermostat is installed, but the fan is direct. Didn't understand the logic behind that at all....

[Xulfiqar]

ustaad logic I believe

Can anyone tell me the how to check if the water pump which circulates the coolant through engine and radiator is working efficiently. when i look in the radiator i see water circulating slowly. also how to check if radiator is blocked or not. my car is khyber and its over heating alot

When your car is cold touch the radiator jaali and see if there is some water check the hose pipe and khyber has a lot of heating issues better to get the head gasket checked and maybe it needs some facing too .

Sir jee same happened with my mehran last year and engine wasn't over heating but when car was parked it used to give thar bubbles coming out from the bottle
i got a liquy moly rad cleaner and used it which made it worse then it used to spray watter and coolant from the bottle and rad cap was cracked due to this boiling and car started overheating
went to a rad cleaner wala he put acidic solution in the rad all liquy moly bakwass came out and no more boiling changed the cap and all done
mechincs were again advising me to change head gasket and head work all overheating was due to faulty radiator the new owner changed the radiator to a 3 nali one and same old car is prefectly fine

[Xulfiqar]

I think you dont know how to flush a cooling system, before you put the cleaner (LM radiator cleaner) - you need to remove the thermostat, drain all coolant etc, flush with clean water with a garden pipe (because more than half coolant/water in the engine remains stuck there) put back all pipes/thermostat housing and put your cleaner and fill with water, drive around for about half hour and then drain and flush everything when it has cooled down to sensible level. Flushing is necessary to remove the acidic contents of the cleaner, otherwise it will keep on working and even destroy coolant etc.

Just draining is not enough.
