I just had a March brand serpentine pulley kit installed and I noticed that I may be generating a BIT more heat that usual. Feels like it and the temp gauge is a tad higher due to the way they're spinning- my guess. Other than a cooler of some sort, what's the next best BASIC item to install to cool the temp a good 50-70 degrees F; i.e.- silicon hoses, fan, new radiator, etc.?
I don't think you need to. If it's only a little bit of more heat, your engine can easilly handle that. Even if it's a lot more heat, again no heat, at least not with the engine. I mean, how hot can it get??? You know how hot an engine gets, right? (if you don't, do a couple laps around town and go and touch the exhaust manifold). The ONLY possible danger I can think of, and even this is a stretch (a long shot at best), is that you might possibly damage the paint job on the hood in the area above the source of the heat.
I might add, I highly object against the advice of the other answerers on this page to put in a lower thermostat! That could lead to MUCH more serious problems in the long run.
Don't worry about it. Leave it alone. It's fine.
