Car Engine Temp rising up!!! Help!!

[Jiayong]

Was waiting for my mom just now when i just decided to make better use of my time and check on the water reservoir(becos i noticed the temp abit higher than normal)....and horrors of horrors!! it had very little water left...

I quickly topped it up.(engine was running)

 

Then when i started moving i noticed it shoot up to almost the red zone!!! wah..i have never seen my temp meter do a redline before!!!

 

I then stopped moving and let it run for awhile...and the needle went down(but still higher than normal).

 

then later on when i reached my destination and came to a full stop..it went up again for awhile before coming down...

 

What should i do guys?

[Burpmonster]

I experienced it b4......could be due to your raditator kanna severe leakage.....better send for checking asap....remember to check water level b4 moving off!!!.......

it could be engine block leaking ( the top where the valves are), so you cant see the leak.

[Jiayong]

yeah mann..for the last few times i topped up water..i found that it got more and more frequent...must be got something leak somewhere.

[Jiayong]

engine block leaking...the water wouldnt drip onto the floor?

[Cheekg99]

also better not top up water when hot, cos' cause more leakage.

[Ahdi]

its either the radiator leakage or blokage ba.

[Jiayong]

just went again for one round...and temp was healthy..must be somewhere leak thats why water so fast finish liao..hmmm..

Yep,

Agree with U, probably the top gasket leaks and allow the combustion hot air to go into the cooling system. thus the high temp whenever the engine run at speed.

You should bring your car to let your mech check.

Don't panic.

 

Check if the coolant's empty. If yes, check for leakage in the hose, cap, etc.

 

If answer to above is 'no'. Then check if the fan is running after the engine is left idling for a short while. It is usually these 2 thing which causes heating problems. The other would be the temp sensor or the themostat.

 

One very important think to note is never drive when the engine temp is very high. It could lead to a blown gasket and the engine may have to be overhaul.

hv u check yr engine oil since? got milky brown colour?

[Arkaneslayer]

milky brown colour means wat?

no, if the gasket leaks then you cant see the water leaking but there will be telling marks.

an experienced mechanic will be able to locate the problem if the gasket is burnt.

[Soya]

means coolant leaked thru worn gaskets into the oil.

[Jiayong]

engine oil?

 

funny that u mention milky brown..the water in the reservior seems to be a little milky brown

water in the reservoir is brown is because the radiator is rusting. Flush it with the engine running and then renew with coolant will solve this. Also change the radiator cap if there is one cos this may also cause leakage.
