about 6 months ago, my 1998 volvo v70 wagon started to overheat. It didn't take long to find that it was a small hole in the radiator end tank. I replaced the radiator and i've still been noticing the engine overheating.. soon after, i replaced the thermostat. No luck. I then replaced the coolant tank and cap, since i was seeing steam from that location. still no luck. my fan switches on right on cue, and the water pump is fine. I also replaced the spark plugs and wires, thinking it was a misfire and there isn't any coolant leaking on the ground . still no luck. i'm kind of at my wits end. can anybody give me a nudge in the right direction?

Is it really overheating? Is it showing hot on the guage, is it loosing coolant or just some steam at the overflow?

When you changed the rad/thermostat did you bleed the system? I'm not too familiar with newer model V but most new cars have a bleed valve at the highest point in the cooling system. This removes any air trapped in there so it's only coolant circulating. Could be the cause of some steam.
