Mike O'Connor researched out the ag oil cooler that Deutz makes for these engines. I don't find it reassuring that there were exactly 0 in stock in the US when he did it.There are on some versions of the engines additional ports to route the oil out to a secondary cooler. If you don't have them, then you would have to go with one of the remote oil coolers that hookup to the oil filter.
i.e. you could splice into the remote oil filter lines from something like this;
Don't forget to add a second fan...
(Not endorsing this one, just as an example.)
To me there are two issues;
a) chaff layers insulating the existing cooler
b) the overall size of the existing cooler
A secondary cooler with sufficiently coarse fins would solve a & b.
Woodlandfarms' modification of the air flow hood does point to some improvements that could be made. The 'standard' Deutz hood wraps across the top of the engine and exhausts over the exhaust, thereby keeping all of the heat on one side.
Altavista rerouted the air path in general for better cooling, and Phils added a second cooling fan. And I believe that Sedgewood upgraded the 14" fan to a 16" fan, resulting in improved cooling. (Anyone recall if he enlarged the opening?)
What did I miss?
All the best,

Ponytug mentioned a secondary oil cooler for the Deutz, and while this is not a serious issue to me (only fall mowing is my grumble) just what and how would one be put in on the PT? It would love to hear your guys ideas on what would work.
For Deutz owners, I lifted the top cover on the oil cooler up 2" and that dropped my temperature by at least 7 degrees, if not more. It is pretty restrictive in its current design.
