Few people can tell if thier cooling fans are running constantly sucking away thier efficiency.
Radio shack can provide ya with a little 12vdc light to tie into your fan circuit.
I say this because Grill blocks sometimes = cooling system chokes.
If your car has a sealed grill port into radiator area and your stopping air transfer it doesnt cool.
The fan running constantly is an indicator that your grill block was effective, but when temps go up outside your cooking your car.
Cars tend to get even, stranding you in worst places at the worst of times.
Ok you have now been warned before summer hits! im done.
