Hey Guy, I've got a question for you since you seem to be very knowledgeable and sometimes getting decent responses on the forum is a little difficult... My 94' that I picked up in March, has been rediculously well maintained by the ONE previous owner. Had a complete top end rebuild at 225k miles, but I don't think the HG has ever been replaced (currently at 285k miles). When I bought it all the fluids were perfect. On hot days like today when I drive for any length of time I can smell coolant at the front of the car when I stop and get out. No coolant smell through the vents, no cross contamination between oil and coolant, no smoke, the temp gauge never moves past the 3/8 to hot mark, idle is perfect, runs perfect, fans work... any thoughts?
