Well they said the engine is malfunctioning and it could be a blown head gasket cracked head ect. Also they do not do any work with heads on my type of car
If they done a block test the fluid should have changed colour if there was a fault , rather than a visual of a few bubbles . You could try bleeding the cooling system and then see if more air returns after using the car .Might be worthwhile getting a second opinion or changing your garage .
How do I bleed the cooling system? I know nothing about cooling systems and head gaskets. I started my car today and it had a odd almost swuealing engine e noise is that bad? I tought of trying bars head gasket treatment for a temp fix because I can't afford a block test or a repair of any kind have over $1000 into the car in the last month trying to keep it running
Could be belt. Get a picture of how the serpentine belt goes, then remove it. The try turning all the pulleys by hand. While it's out, inspect the belt.
I have only ran the car to get it back home but here are my symptoms it blows thick exhaust I have little air bubbles in the radiator (cap on or off) no loss of coolant and it has not over heated yet. Only ran for 4 miles to get home going about 25 mph and the squealing serp belt that was changed. Oil looks like its dark for just being changed. Any ideas or is this still a head gasket issue? No check engine light yet.
If you are getting air in cooling system and thick white smoke normally would confirm head gasket blown / head cracked , or both .As already suggested , a block test will confirm or not .Also get cooling system bled and see if it helps , though doubtful now from what you describe .Then see if bubbles in cooling system return .Depends where the gasket blows whether it mixes with oil or comes out exhaust .
