Sir Sam Posted March 14, 2011 Share Posted March 14, 2011 New Radiator and source some hoses from a 91+ HO. Link to comment Share on other sites More sharing options...
Eagle Posted March 14, 2011 Share Posted March 14, 2011 The hard part is finding a way to control the auxiliary fan, since the early system uses a sensor in the driver's side radiator tank to activate it. Link to comment Share on other sites More sharing options...
RDAN1 Posted March 14, 2011 Share Posted March 14, 2011 The hard part is finding a way to control the auxiliary fan, since the early system uses a sensor in the driver's side radiator tank to activate it. Is it possible to buy a new radiator with a spot to mount the existing aux fan sensor? or to add one to an XJ radiator at a local radiator shop ? ?

The ones I've seen (including the new style that the radiator shop got by accident when I ordered an old style radiator) did NOT have the bung. So I guess they exist, but I don't know where.

mvusse Posted March 15, 2011 Share Posted March 15, 2011 Another option is to use the original radiator with a universal cap adapter in the upper radiator hose, or use a HO thermostat housing, which has a temp sensor for the fan. Link to comment Share on other sites More sharing options...
Eagle Posted March 15, 2011 Share Posted March 15, 2011 Another option is to ... use a HO thermostat housing, which has a temp sensor for the fan. The problem is that most sensors available are either variable-resistance senders rather than switches, or don't switch on and off at the correct temperature. Of course, if you're willing to settle for controlling the aux fan manually, with a switch on the dashboard, then there's no problem. Link to comment Share on other sites More sharing options...
