Post by Toast »

Hi there.
Sorry, I know this is a stupid question .
I have a ld20-ii engine and I am missing a coolent pipe, and I can't find where it goes to. It starts under injector 4 (pictured below)

Can anyone shed any light on where it goes?
Thanks in advance.

Heater hose maybe...?
The old 'six gun' was as popular as the cell phone in its time and just as annoying when it went off in the Theater.

Heater hoses are on the other side of the engine and plumbed in.

Probably the oil cooler where the oil fitter screws on but I'm not sure.

I believe the other side goes to the oil cooler, I'll have a look later today and double check.
