Heater core was leaking in the 94 3.0 auto Ranger that I bought last week. Pulled the old core out which was very easy. Got a new one from Rock Auto and have put it in. Bought 5/8" heater hose by the foot from advance auto but now that I look at it I'm not sure this is the correct size hose. The Haynes and Chilton books that I have aren't helpful at all on the subject.

Is 5/8" the size hose that should run to and from the heater core?

Thanks in advance

Mine are 1/2 id. Have got by with 5/8 though.
 
Just finished putting new heater hoses on my 94 3.0 auto.
Note: If you are going to do this job at least one of the hoses must be the factory (style) hose. The stock (by the foot) 5/8" hose worked fine for the upper hose. The lower hose has a 1" end that connects to the water pump. For maybe the last 2" the hose is expanded to 1" the rest is 5/8". That lower hose was a bit$h to get on. I sprayed the hose ends and all of the connections with WD40 prior to starting to slide them on - still really a tough job on that bottom hose - just no room to work.

So anyway the job is done and I now have heat when I need it.

Great job to do today as it's supposed to be 85 here tomorrow.

Only reason I did it now is I'm motivated to fix things on the truck now since I just bought it.
