75 series coolant leak

[austoy97]

Hey all,
1997 75 series ute. I have a sporadic coolant leak- mostly the reservoir drains every week or more.
I think I’ve tracked it down to a pipe leading from the firewall to the engine. Any ideas what this hose is? Symptom of a bigger problem?

Cheers

Normally the only water going in/out of the firewall is the heater

Heater supply hose. New one and new clamps should solve your problem. Hose, Water PN 87245-60160. Might be worth checking the water pipe in the block that the hose attaches too also. Pipe, Water By-Pass, No. 2 PN 29300-17010
