Re: Oil thickener?
Think about that one for a sec. If an additive can thicken hot fluid, what does it do to cold fluid?
Tar was the first thing that popped into my head.
I deal with thick fluid every time that I start my tractor in the winter. The loader is very slow with zero payload in the bucket until some heat is generated. Then it's just slow for a while until I work it enough to get the fluid up to a decent temperature.
A thought. Is the oil cooler in the rad? Radiators typically heat the fluid to 175-180į. Perhaps you might bypass the cooler to keep the temperature down, unless you're running a hydraulic motor. I know that my system doesn't get up to that temperature doing loader work, even on a hot summer day. The cylinders and the lines offer lots of heat rejecting surface area. If the tractor is idling for extended periods, cycle the cylinders full stroke periodically to exchange the relatively cool fluid in the cylinders for hot fluid from the reservoir.
It might help until you can get the pump rebuilt.
