Over heating problem

[poiuyt]

Good day..Matagal na ako ng babasa dito for different info kaso ngaun lang ako nagregister.

Here is the problem.. Nag ooverheat pa rin un kotse namen after palitan ng bagong radiator, sensor (di ako sure kung sensor talaga tawag) at nag pa top overhaul na rin kame.

Nag pa diagnose kame sa ford service sa alabang at wala sila makita bat nag ooverheat at nagrecommend sila ng top overhaul. Kaya nag pa top overhaul kame sa friend na mekaniko ng father ko(Di ko alam un details sa mga ginawa sa top over haul kc father ko un libre that time)..After nila gawin, naging maganda un takbo at di na rin nababawasan un coolant.

2 days after ng top overhaul..tinakbo namen un car laguna to manila pier at pabalik.. No overheat na nangyari pero sa 3rd day after ng top overhaul ng overheat un kotse habang tinatakbo namen sa area namen..

Any advice will be a great help.. Kotse pala namen ay ford lynx 2003 at nasa 67k na un tinakbo. Thanks

Describe the conditions in which the overheat occurred... was it running? What speed? Was it sitting at idle?

A lot of conditions not visible on the computer diagnostic can lead to overheating... cavitation at the water pump, a slipping water pump belt, weak radiator fans or even a timing problem due to a camshaft out of alignment.

Forgot to tell something... Nun nag overheat pala nasa low speed lang around 20-30 kph then sumagad un temperature sa pinaka mataas at tinigil namen sa gilid ng daan at pinatay ang makina.. Tinignan ng father ko un makina mga 1-3 minutes lang.. then on ko ulit un engine..nasa normal temperature na at naka uwi na kame ng walang incident ng overheat o kahit pag taas ng temperature.

thanks sa reply.

Might be a fan issue, a problem with the overhaul (though there shouldn't be if it was done at the casa) or even a boil over of the fluid.

What coolant are you using? (or are you using coolant at all instead of just plain tap water?)

Was the system purged of bubbles? If it wasn't, it could be that the coolant started to boil due to air trapped in the system.

we used coolant from total.. siguro naman un fan is ok kasi top over haul lang un rinicommend nun sa casa..

May chance p rin ba mag bubbles kahit bago un radiator? di ko alam kung na purge ng bubbles un system..(newbie din kc kame sa car)

thanks you sir will check again dun sa mga sinabe mo..

Good luck!

A compression test will also help tell you if the overhaul was done properly. Not many shops carry the equipment to do it, but it's relatively cheap and quick.

3min. lng po b pinatay ang makina then nung inistart ok na ulit? kung meron po kc yan overheating kung sumagad ang temp.gauge nya dpat puede n magoverflow ang reservoir tank ng radiator, at di po yan kaya n mwala agad within 3min. lng n patay ang makina it takes less than 45min b4 bumaba ang temp. gauge, possible po ang problema nyan kung ganun ay yun pong electrical wirings nya, pacheck nyo po ang temp.sending unit if accurate, thermoswitch if accurate.. puede rin po n bk delay signal n sya pra paikutin ang rad fan motor kaya umaangat angat ang temp gauge nyo..
