oversize vs mpg
My honda radiator is probably the original, going into it's 16th year, so I'm going to replace it. An oversize with higher thermostat and blocking the grill will hopefully not hurt mpg. I want to get a 195 thermostat, aiming for a constant temperature of 195-200, which will hopefully keep the engine warm enough with an oversize radiator.
The fan coming on at 185 is an issue. I want it to not come on until 200-203 degrees but haven't found a civic coolant temperature switch in this range. I might need to install a remote switch, or a temperature gauge adapter with a different switch. In the meantime, I've unplugged the switch and will keep close watch on the gauge.
Below are three of the radiators I'm considering. Let me know your comments.
1) $55 ~ .63" standard radiator with plastic top like the one I'm replacing;
2) $50 ~ 2" all aluminum that I like the best;
3) $62 ~ dual core all aluminum, that I might get because of the fan.
