Does air in radiator increase warm up time?
 

I'm hearing splashing in my dashboard like heater core is clogged but it is not. Just wondering if I can burp the air out, will it heat up faster in the morning?

If you hear splashing, the heater core isn't clogged, there is something leaking.
Don't drive your car untill you managed to get that fixed or you might damage your engine.

Else it might be rain-water in the ventilation system. Does it rain in Istanbul?

Also, welcome to Ecomodder.

Air in radiator may increase the likelihood of a vapour-lock within the cooling system, with an increased risk of burning the head gasket and eventually bending the cylinder head.

Lol you all are responding to this like it's a real question when they included a non functional link to a digital marketing agency right in their first and only post.

Who knows...

Maybe give it time to play out?

Some of the best threads have been abandoned by their OP, it sorta frees up the discussion.

1) could it be the blower striking water in the fan housing, caused by a blocked condensate drain during air conditioner use?
2) I experienced this with a friend's package window air conditioner unit.
3) the buyer was required to drill out a factory located drain hole, which they failed to do.
4) If you have high humidity and flying insects that like to build nests inside machinery, it could explain what's happening.

A friend recently complained about some strange water noise from the heater core on his car. Gotta have to check this.
