A couple questions here for the wizened -- I mean wise --- listees.
On the 1.9 auto transmission version, Bentley page 19.10 shows that when
the engine thermostat opens, a portion of hot coolant heading toward the
rad gets routed through the ATF cooler and back to the engine, bypassing
the radiator.
When the Gowesty ATF cooler is installed, the two coolant hoses that
formerly went to the stock ATF cooler are joined, provided a very direct
bypass around the radiator.
Manual transmission versions don't have the ATF heat exchanger coolant
bypass.
So we have three versions of the 1.9L wasserboxer cooling system: stock
with rad bypass through ATF cooler, GW external ATF cooler with direct
rad bypass, and manual has no bypass at all. That's what I'll get when I
remove those two former ATF cooler hoses and plug them.
Anyone care to speculate what effect on engine heat these variations
might cause?
I ask because Marius Strom installed the same Gowesty ATF cooler on his
van as I did. Like me, he has the two hoses that formerly went to the
ATF heat exchanger joined together. He has noticed that his temp gauge
reads a bit higher now
( <http://www.thesamba.com/vw/forum/viewtopic.php?p=5353379> ).
Also, is there any benefit to warming the ATF? This would be the
condition with the stock AT setup when the thermostat has opened. I
presume that once up to temperature, the ATF gets so hot that it
actually dumps heat into the coolant.
And finally, can anyone tell where on Bentley page 19.10 the temp gauge
sender is located?
