Diagnosing this will be subject to a process of elimination. It could be the radio, blower motor or any other accessory particularly ones with moving parts; Try switching those off and try to note when this problem occurs and what is on/whatyou are doing. Something is getting hot causing the smell so it will be a situation where the accessory will have to run a while before doing it. It is a possibility that there is an electical curcuit overheating, but less likely. Lets rule out accessories first and give us an update. GL

drain the coolant.remove belt by rotating belt tensioner cllockwise. water pump pulley will require a holding tool to keep it from turning while removing bolts. access to air ratchet can sometimes eliminate the need to hold but be careful cause thats a good way to skin some knuckles. also make installation more difficult to obtain proper torque. after pulley is off just a few water pupm mounting bolts remain. clean and dry gasket surface very well before reinstalling.

Testimonial: "Very quick with a response, and good info!"
u have a leak in the heater core the oily smell and mist is anti freeze sounds like a small leak because usually u would have a wet floor if it was large -two choices check and repair as necessary the core or can use an additive with a stop leak they usually work well on small leaks
