If it aint leakn' much, just top it off. My truck leaks a little over the course of some time and I just top it off cause I too lazy to fix the leak....then again it's a 1988 with 180k on it lol
I feel more like i do now than I did before.
I'm having a similiar problem. I can smell the coolant so I just assume it's one of the several o-rings in the coolant system. I don't know about your R, but on H series. there's two o-rings that go on both ends of my water tube on the back of the black. One end runs from the back of the water pump to the back of the thermostat housing. H-series also has a oil cooler with an 0-ring that leaks from time to time. Those are the only coolant spots that I can think of that couldn't be seen from above the engine.
SWEET! E36 radiators are the best :bow:
