    Take the bashplate off underneath the engine. Check behind the waterpump pulley for a telltale droplet before you start in the morning. there should also be a telltale mark under the bonnet where it sprays water from the belts. Check that radiator cap seals proper. Look for any discoloration around pipe joins and clamps and behind the waterpump pulley. When the engine has reached operating temperature and using the wifes vanity mirror, use the mirror to check for steam from a broken pipe or leak.

    Is the system pressurising at all? Seen a few that have leaked into the EGR system through the cooler on the side of the head. Could be worth a check as well as a last resort.

    Mine isn't an Isuzu but to show how easily a leak can be missed on a water pump, here's mine.

    I didn't see a loss in water but a change in water temperature.

    I had an idea something was wrong but only found it with a mirror. This was bearing seal failure.

    If the temperature is rising and losing water,(pressure loss) there is definitely a leak somewhere. Cracked head, check for air bubbles in the radiator and it can overflow into the reservoir/expansion tank.( only when hot) It also depends where the head is cracked. Could be into an exhaust port. But we are making a mountain of a molehill at the moment. Check the other things first.

    As jou pomp nie lek nie, en jou heater core in cab ook nie, is kans baie goed dit is of headgasket, of top wat gekraak is en na exhaust toe stoot. Nie terwyl jy ry nie, maar bietjies bietjies elke keer as jy kar afskakel. Dan verloor hy water na combustion chamber terug vanaf radiator

    Nie seker van isuzu, maar as hy n non pressurised expansion bottle het, trek pypie van radiator nek af, vervang met ander langer pypie wat jy in n glas bottel hoer as radiator laat staan, met pypie sumerged. Maak radiator tot bo vol, sit prop op, start bakkie. Nou wag jy vir borrels in bottel

    If you have a mate with an exhaust gas analyser, remove radiator cap when not dangerously hot and check for any exhaust gas in radiator - you are looking for hc and/or co.

    Alternatively get a radiator company to do/use a combustion leak test - fluid will change colour.
