Hi Y'all! My 1990 Ranger 2.3L SOHC 5 spd, has just about had it with the thermostat housing being worn out, and I for the life of me cannot find a suitable replacement for it. The newer style is plentiful to find and brand new of course, so my question is what do I need to do or change to be able to use the newer style thermostat housing / Water Outlet with the 1990 engine?

The 1990 I have has the Spark Plug coils on on the left and right hand sides, whereas the newer style has them both on the right hand side next to each other. Would I be able to source the brackets, make a harness to move the left hand side coil over to the right hand side as the later years do, and with some heater hose re-routing, and wiring harness extension and be able to use the newer style of Thermostat Housing?

What all parts would I need to get this to happen? Would the new style even fit without hitting the timing cover? I tried to fit a newer style one on there in desperation, but it hit the coil bracket on the right hand side, and the heater hose outlet on the newer style one wasn't even close to the old OEM one. Because at this point, I'm not too sure how much longer my truck's original one is going to last. Gurus, tinkerers, and other people please chime in, I could use all the advice I can get, because my last resort is to have one fabricated up, which costs a whole hell of a lot more than a four seasons one from RockAuto. Thoughts and insights super appreciated!!

Kind Regards,
Nubs
