Okay, our Project 240 has had some issues as of late. This is the first summer we've owned it, and we're learning it has a propensity to overheat. The thermostat and the water pump have both been replaced and the radiator has been looked over pretty well and we're confident that it has full flow.<P>Our shop that was doing the work on it thinks it might be a head gasket failure or a crack in the head. I'm not in disagreement with that, but that's an expensive proposition and one that isn't guaranteed success (though probably will). Plus, it's more money than I'd really want to invest in a normally aspirated automatic car. However, an engine swap might be even more expensive, though I would have more hp. Trouble is, doing our kitchen this summer, the funds aren't really there to do anything crazy.<P>Also, Rob (Volvorules) ran a compression check on the motor and I'm good in all four cylinders. Further, the coolant is clean and I see no coolant in the oil. I'm blowing no smoke out of the exhaust. This all makes me believe that maybe I've overlooked something....somewhere.<P>It appears with the car that it is only overheating when the oil temp is up. I just took it out for about a mile to two mile drive and returned to the house, let it idle for about ten minutes and it was fine. However, once you get everything at full temp and run on the highway....then stop in traffic, it's a different story.<P>Turning the heat on high will bring it into range again, but heat in the summer is no fun.<P>So what I'm wondering here is if anyone has any suggestions?<P>I can't help but think that maybe I should try doing a larger capacity (6cyl) radiator, or an oil cooler. I know Volvo made an accessory tranny cooler, but not sure about an oil cooler.<P>Any of you 240 gurus wanna take a stab at that?
