Coolant question
About a month ago I put a 95% upper grill block on my truck and last week I finally forked out the cash for a ScanGauge. I checked the water coolant temperature with the Gauge after it warms up and it seems high to me. When coasting in neutral it drops to 202 °F and when I'm on the freeway it goes all the way up to 209 °F. Is this normal? I don't have a lower grill block so I think it's getting enough air.
