Cooling system question

[REV-I-DOO]

Newbie here in need of some help...............

 

I picked up a '99 shee and the small coolant hose that goes from the head to the top of the radiator has been cut and blocked off.

 

Any reason for this?

 

Why would the previous owner do this?

 

Do I need to replace the hose and hook it back up?

 

Thanks.

It's my understanding that this Line is a Steam vent . Propose is to remove air bubbles in the Head to Cool it better. With an Air bubble in the head you Loose the water contact to the interior walls which reduces thermal heat tranfer.

 

Fix it Soon .

actually the hose isnt a steam vent. you shouldnt have steam, but if you do thats that the over flow bottle is for. that line is a vent, but its to release air trapped in the head. with out it youd have an air bubble on top of the head that couldnt be removed with out vacuum bleaind of the coolant system. so yes replace it. its a piece of straight hose that goes into the top of the radiator.
