If you park your truck outside please pop your hood and make sure no rodents has built nests in the engine bay. I took my truck for a drive and when I got home smoke was rolling out of the engine. In a panic I finally got the hood up to discover flames coming from behind the motor! I quickly got a fire extinguisher and put the flames out. I discovered lots of dried leaves and material from rodents building nests. I have no doubt it would of been a total loss had i not had that fire extinguisher. I think everything is fine. I tested all functions I could think of. Rodents seem to love the foam engine cover. Anyone have any suggestions to keep rodents out of the engine bay?
