Advanced timing.

Can anyone put mein the right direction to work out or just tell me what my timing should be for my Honda Accord f18b non vtec, i have had it on a diagnostic tool and it says it 15degrees advanced, does this sound right, I've had all sorts of heating issues when under load on inclines and cruising constant around 100-110k's, around town it's sweet as, temp sits below half way, I been told ya timing can cause heating issues, cheers.

Probably should check for blocked radiator first.

Yes if too advanced will get hot but ul notice it will pink ineither run on or kick back when starting
Was it in dianostic mode when check timing!

retarded rather than advanced timing usually leads to higher than normal engine temps. Also on the Accord the ECU should be able to dynamically adjust timing anyway. If the timing is too advanced the knock sensor will detect pinking and then the ECU will retard timing to suit. It does indeed sound like a blocked radiator or a failing water pump (fins eroded away).

There's a million other things more likely to cause significant heat issues than ignition timing, which I've never really thought of as causing overheats, only performance and pre ignition issues.

Start with the cooling system.

Philip is right. Retarded timing makes motors run hot. If old non-computerised engines get really severallyadvanced they will get hot, but that is because they are struggling to develop power and before they get to that degree of advance you will notice other symptoms before the heat.

In the case of modern motors, the ecu will retard the timing if they detect pinking.

And, you will need to lock the timing to the fixed start-up condition before adjusting it. There's probably a connector somewhere to do that.
