Runs ok but blowing whitish blue smoke.blows even more as i accelerate.no overheating but when radiator cap is off and engine is running the water overflows out the radiator.any advice pls
That is probably the head gasket leaking. White smoke is from antifreeze going through the exhaust. The engine compression is pushing the water out of the radiator.
Testimonial: "thank you..I managed to get it looked at and got it sorted now and you were spot on..thanks again...x"

SOURCE: ford ranger truck overheating
I have had this happen with my ranger. Changed everything I could to try to fix the over heating. It turned out that I had a small leak in my head gasket and it was allowing exsaust gas to go into the cooling system witch was over pressurizing it. Also the air from the exsaust will heat up much faster than liquid making your thermostat to read hot and will not be able to blow hot air in the cab because there is no liquid going to the heater core. This happened to me when my blet came off and I tryed to make it home. If you had it over heat for a long peirod of time it may have ripped the head gasket.

I have a 2005 F350 and mine was doing the same thing. We changed everything including replacing a new factory overflow cap. Finally, we found that the head gasket was leaking causing the engine to overheat but also I was loosing a ton of horsepower. We rebuilt the engine from the head gasket and new heads all the way to the top of the engine. We replaced the head bolts with new head studs and it feels like a new truck. More horsepower and it pulls like the beast that it was meant to be. Hopefully, this helps good luck.
