cooling water hose size on 2GM???

Hi folks,

I looked, but didn't see the hose sizes in the on-line manual!

Anyone know the size off hand? Mine is raw water cooled, but I am looking for the ID size of the hose coming from the block / thermostat, going to the exhaust (or heat exchanger, on fresh water models).

I need to replace the hose as it goes to my Force 10 water heater. The force 10 manual says their fitting is 5/8" hose barb. I ahd it hooked up last year, but had a hard time fitting the hose on the 5/8" water heater fitting. If I knew the proper engienm hose size, I will know if I need a reducer, etc.

Thanks in advance!!
