remove heater core bypass hose and simply plug it

[bambino]

if that's intended for heater core there shouldn't have a negative effect on your cooling systems if you decide to remove it

Yup. Many cars without heater cores come with plugs on those attachments.

If there's nothing wrong with the hose, though... just keep it as is... changing it for plugs won't give you any extra security... in fact, pressure building up behind the plug might make it worm its way loose over time... happened to us in a Civic a few years back... we replaced the plug with a rubber cap meant for the leg of a footstool and fastened it with an O-ring (this happened on a Sunday... no auto-shops). Far as I know... now that the car is with the next owner... that cap is still there...

Keep the hose... or just replace it with another one.

actually, there is no problem with the hose. ka ek ekan ko lang kasi harang sya e. its hard to reach the parts under the hose. hassle kung baga.

Ah. Ok. You can plug the outlets... some cars come from the dealership with plugs instead of a bypass... but IMHO, it's not really worth doing.

This happened to me yesterday on my wrangler with 4JG2 engine it seems that the hose used to bypass the heater core got a crack in it.good thing i noticed my engine temperature fluctuate so i pulled over and took a look at it and to my luck it happened in front of a auto repair shop.It does look kind of ugly and the bypass hose also gets in the way. It is very important to check and replace radiator hoses regularly dont wait for them to leak or break.this little things if left unattended can lead to more expensive repairs (overhaul).
