External oil cooler hose size

I have a Vanagon 1983 with 1.6D na engine. Adding external oil cooler. I got all fittings from local hydraulic shop. I thought I was supposed to get 5/8 ID hose, but doing more reading it seems like 1/2" ID is better. I already bought 5/8". Is that too big? Will my oil pressure suffer? Mounting cooler in front of transmission and using thermostatic sandwich plate. New to this. Any feedback greatly appreciated.

I'll try the 5/8 and report back on any issues.

5/8ths sounds to large for my tastes. That sounds more like water cooling size. I used a sandwich between the flange and filter for an external Frantz cooler and I think the inside diameter of that hose was closer to 1/4 inch. Once it got to the external filter it had a sleeve in the inlet that dropped the diameter down to 1/16 I believe. b
But that particular filter is not designed to have a huge flow going into it. You are also looking for flow to cool the oil so I would venture a guess that you are a bit big on diameter. Maybe drop a couple of 8ths and go with a 3/8th if you find you lack pressure.
The oil pump only can produce a given volume depending on RPM. Flow is a measure of a combination of pressure and diameter of hose. A given volume will be at a higher pressure with a smaller diameter hose.

Thanks a million. I have already purchased 5/8 to 3/8 hose reducers. The fitting for the oil cooler are 5/8 so that is what I was going with but that could be for a Jaguar or something. Peace

I’ve run 5/8 in the past, with no issues.
