Question about Cars & Trucks
Not an oil smell but some other fluid burning smell. No signs of leaks or alarms or indicator lights, just weird smell.
Check the wheels for excess heat by feeling the rims are they hot..is there a sweet sort of odor(usually associated with antifreeze) and it will send up small plumes of smoke usually steam or white in color..check power steering also..does the car shift ok when running..transmission fluid gets cooled in the radiator in most models..there are plastic ducts that are close to heat sources in some models also..some of these were to be removed by dealers after break-in mileage was achieved but never messed with on some cars.. this caused underhood fires and was a recall item on some models..check for recalls on yours and see if anything matches.. good luck and repost findings..

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

if the smell only comes on when the heater is on try pulling the blower motor mice like to build nests in the blower motor housing.

A burning rubber smell under the hood might be just that - consider having your accessory drive belt inspected, as it is possible that a bearing in one of the accessories (alternator, power steering pump, air conditioning compressor, etc.) or in the tensioner mechanism might be failing. This sort of fault will often cause that particular accessory bearing to spin less freely than the others, and as a result the belt continues to pass over the associated pulley at the same speed as the engine. Essentially, the result is similar to a car spinning its tires on dry pavement - and a similar 'burning rubber' odor is the friction and heat of the rubberized belt.
If the odor is more like burning oil than burning rubber, the rear valve cover gasket is situated in a place that results in dripping oil, even small and unnoticable amounts, onto the exhaust manifold that is directly underneath the valve cover.
These two items might be places to start your inquiry. Best of luck to you!

probably not. put aluminum seal in the cooling system and top off antifreeze. you may need a hose or fitting from where you are decribing the leak. if the leak stops with the sealant you are good to go. otherwise take it to a shop and they will tell you. do not tell them you think it is a head gasket.
