Anyone else had a Coolant Leak from the Heater Hose Connectors?...the leak for mine has developed over the last 600km or so....

Ordered parts on Monday they arrived Thursday

Fig: New Hoses Quick Connectors, Hose Clamps & Rad Cap

Had some time so replaced the Heater Hoses & Quick Connects

Remove the Battery, & ECM/Air Filter Cover, makes access easy for the Heater Hose replacement. You don't need to remove the standard air intake/plastic over the coil packs.

About 1Hr all up then 10 min drive & check the heater hose connections, then a 1/2Hr Hway run & checked the heater hose connections for seepage
Checked the coolant level the following morning when car was cold & topped up coolant header tank. Also checked the Heater Hose connections & Radiator Drain Valve for seepage

All good.
