Diesel Radiator Service Hilux 3L

[cheems9]

aslamoalekum,
i’ve got my radiator serviced from chaburji, lahore
after that, i’ve checked it on daily basis, around 500 - 700 ml, level is decreasing.. and the level remains the same.. whether two days of seven days have passed..
couldn’t spot a leakage though

didn’t start the engine for around two days, not a single drop decreased

asked a hommie, he told me that after service you gotta wait for some span of time to get things adjusted
which, i don’t understand, cuz it doesn’t sound logical

please, need expert’s opinions

It's gradually burping air out after service so coolant level dropping is normal. Only burps when coolant cycle is in process which obviously happens when engine is running. Keep filling on cold until it stops.

[cheems9]

same goes with water, yeah?

[Proverbial_Slang]

Water should not decrease. The so called service has probably resulted in a pin hole leak somewhere.

perhaps the air is not purged from the system after radiator is re-installed.
remove radiator cap, install a large funnel at radiator collar start engine & leave to idle for 15 minutes. or there shall be clutch fan engage & disengage 2 cycles keep a close watch over funnel there will be significant burps and varying level of coolant during idle.

sir @rajaatta @dani_kk @syncview @Hassan1991 may pour some more detail

[rajaatta]

It seems like radiator cap is faulty.

[dani_kk]

The radiator tank usually gets seeping after radiator service. So it can only be traced with the help of coolant. So buy any cheap coolant and remove all water and pour in coolant and then check.

[cheems9]

if there’s leakage.. why ain’t water level decreasing.. checked the vehicle for two and half day, without atarting the engine

[dani_kk]

Radiator tank seepage tends to appear when the pressure rises in cooling system. It's not like there's a big hole inside that will start spilling like a water stream down.
