RCP Phx,
With all due respect. I don't feel that this is a "band-aid fix" at all. When I first bought my 00XJ, the engine compartment had a plastic cover that completely sealed the bottom of the engine compartment. So the only air entering the engine compartment was through the radiator. The only exit for the hot air was to flow pass the bell-housing and downward. The air flow appeared to slow and "dead-head" in the engine compartment and raise the engine temperatures. I chucked the plastic cover, cooling improved and engine temperature went down. Likewise the riser blocks, to raise the rear of the hood, also increased air flow out of the engine compartment and lowered the engine temperature more. Likewise, my modified 88XJ (Static CR: 11.25:1) has been running the riser blocks on the rear of the hood, for about 300,000 miles now. The riser blocks help to remove more hot air from the engine compartment and the engine temperature is significantly lower. Getting the hot air out of the engine compartment is key to lowering engine temperatures. In my son's 69 Camaro, with a 4-row Griffin radiator and lowered body, the fuel would boil in the lines feeding the carb. After installing a heat insulator and a heat reflective aluminium sheet under the carb and tape insulating the headers, the final fix was to cut exhaust vents in the fenders to get the hot air out of the engine compartment and cool the engine down. Then the 69 Camaro ran fine in heavy traffic and 100+ degree days.
So you and I will have to agree to disagree on what you view as a "band-aid cooling fix".
Best regards,
