Drilling thermostat

**Halon** · 08-23-2007

The car seems fine at lower speeds, and worse at higher speeds. Just letting the car idle or sitting at stop lights lowers the temp.

As for the radiator, it did this on my old radiator, and this whole thing is the reason I bought the new radiator. Here is the one I have.

I'll look into getting a new temp sensor asap. I'm going to update my first post as well to show everything I've done thus far so you don't have to siphon through a bunch of pages of crap.

Also, I have the thermostat currently completely removed.

That might be your whole problem right there. Unregulated water flow can cause overheating at higher rpms. No time for it to cool down in the radiator.

This means it is not a normal cooling problem. If you just had a lack of cooling, then it would get hot around town. Do you have an EGT guage? This is one of the times that one may come in handy. Is it possible that the DSMlink timing isn't set the same as the engine? Running too much timing will raise the temp, as will running too lean.

this might be dumb but are the fans going the right way. craig had the problem of overheating down the road and the fan blades were not on the right way to push air from the front.
