Cooling system ng CRV (1st gen)

Napansin ko lang ito nung nag-drain at replace ako ng coolant ng CRV ko.
Nung napalitan ko na, i started the engine. Di ko nilagay yung radiator cap. Then after a minute or so, umapaw yung coolant from the radiator. I tried revving the engine and then mas bumilis yung pag-apaw. I was told that this is not suppose to happen. Dapat daw nung nagrev ako, hinigop yung coolant instead na lumuwa.

Di ko pinansin yun noon. Ang inisip ko lang na natural na mag-expand ang fuid kapag uminit. Kaya nga may radiator cap. So, pinatay ko engine then I added some coolant para eksakto. I made sure na nasa max level doon sa reservior.

The last time I checked, di naman siya nagbabawas ng coolant. Nasa max level naman naman sa reservoir. Di rin nago-over heat. Pero baka symptoms na ito na may problema na sa cylinder head.

Ang isang problema lang na nakikita ko, may oil seep coming from the cylinder head area.

Any inputs? Thanks a lot.

I found this in another thread:

"subukan mo muna ibleed. baka may natira pang air pockets sa water jackets.

remove rad cap and race engine several times until no large bubbles bloat at the rad neck. then refill with coolant when cold."

I forgot to mention na nung umapaw, may large bubble muna sa radiator neck.

So, this probably means na normal yung nangyari sa crv ko.

up ko lang.

wala problem crv mo. normal lang na mag bubbles sa umpisa after mag drain and fill ka ng coolant.

dapat binuksan mo yung bleeder ng cooling system para mawal yung trapped air
sa hose at manifold.

agree ako dito at need mo lang to properly bleed. in relation naman dun sa oil malamang sa valve cover, cam plug, distributor lang galing yun.
