its a pretty weird problem im having, i was drving about 45 minutes in traffic with no signs off overheating... then i get on a pretty dead highway, going about 65-70 mph, i then notice my temperature needle rise towards the h, then when i decrease the speed to 55 mph, the needle goes back to normal, what couild it be??? theirs enough coolant inthe resorvoir and i know the fans r working, what else could it be hope it isnt an engine internal problem, maybe radiator?

 

anyone have an idea?

 

no helppp?

 

could be headgasket, are you boosted? or stock

 

First, do you have a proper coolant level in the engine? If there's an air bubble, it might do that.

 

i was hoping it wasnt the head gasket, im completely stock no boost wutsoever, but its a weird problem, i was in traffic today all day with the a/c on and no problems, but when i go over 65 mph my temp needle rises, the coolant level is fine and i put coolant in my radiator as well, the levels are fine, is a radiator clog possible cause when i opened the radiator cap i saw little black stuff floating in the antifreeze

 

Yeah, could be clogged. It makes sense. Heavier load, more heat, but nowhere for the heat to go.
