Please help my corsa 1.4 d is not turning on but the battery it has power also it gives problem with over heating the water boils after just few minutes after turning on the engine

Change thermostat. Put antifreeze in the system, it is better for not boiling because it is Glycol. Maybe blocked passages so give it all a flush. Maybe failing water pump. Also you may have airlocks in the system means the water doesn't circulate.

There are two fuse boxes in the engine bay and the big one has THREE relays for the cooling fan R1, R2 and R3, although not all positions may be filled.

BUT, it could also be the cooling temperature sensor.

Do you know how to test a relay? Do you have a multimeter and some wire?



The coolant temperature sensor can also be tested.

How to Change an Alternator Removing the Serpentine Belt

I see two possible causes.
1) Something is blocking air from cooling the radiator. Is there any debris like leaves blocking the radiator?
2) Something is preventing coolant from flowing through the engine. Could be a water pump failure.
Make sure your engine old level is within proper range.

I had the same problem with my Corsa Lite Sport. Try turning the ignition key slightly counter-clockwise when you hear the clicking.

if the water in your radiator or reservoir is boiling means your cars engine auxilliary cooling fan is not perfectly working enough to dissipate heat inside the radiator( heat exchanger) check cooling fan if its silicone oil filled if its rotating free and no resistance then remove fan and refill silicone oil/ if its equiped with electric fan then fan motor is busted

if the rad has no cap then there should be an external expansion tank, with a small water pipe running to the rad, this circulates the water, make sure you dont get confused with the windsheild washer tank, may sound silly but has been done lots of time!

i had a 1996 s-10 Blazer that did that when the alternator went out...it overcharged the battery and boiled all the water out of it... i tried to make it home which turned out to be a big mistake.... battery then lost charge 5 miles from home... had to get a jumpstart.... 1 week later my transmission went out... it shifted electronically and with no battery power it didnt know which gear to use so it burnt itself up.... I kinda think the alternator warranty should have payed for the transmission

could be your thermostat then if the radiator is not leaking if it was a cracked head you would notice ur car loosing a lot of power
