#BEST RADIATOR STOP LEAK MANUAL#
Without Oil or Transmission Coolers, for base model C5 with manual transmission & Z06’sĮ. Cut down version for easier supercharger installation clearance, with integrated transmission coolerĭ. Integrated dual 7-plate Transmission and Engine Oil Coolers, 1997 to early 2001 with flare line fittingĬ. Multiple configurations are available to accommodate transmission oil coolers, engine oil coolers, or even a cut-down short version for the supercharger guys.ī. The 2-1/4” thick core increases the coolant capacity with an extra gallon of coolant and the dual 1” wide core tubes contribute to a 25% increased cooling efficiency over a stock radiator. Zero custom fitting, fabrication, or modification is required. These Direct Fit radiators live up to their name. The talented craftsmen furnace braze, TIG weld, and assemble each radiator. The DeWitt’s unit will never see those issues, which is why aluminum is better than plastic.ĭeWitt’s builds their radiators right here in the USA. As I have had 2 GM trucks with the same radiator design develop cracks and leaks in the past, I wasn’t surprised to read that C5 Corvettes have the same issue.
Not only are there a large number of racers recommending a DeWitt’s radiator, but the team at DeWitt’s have been active on their social media by posting very detailed responses to forum posts and helping the community out by providing their expertise.ĭeWitt’s uses one-piece TIG-welded aluminum side tanks for their radiators instead of the factory crimped-on plastic end tanks.
The brand for C5 Corvette radiator replacement I saw recommended time and time again was “DeWitt’s”. So after destroying my engine with 6 worth of stop leak and a 'buy me some time' radiator repair. While the C5 Corvette is far too old for GM to worry about extending any coverage on the factory components, you can clearly see that GM admits that they didn’t put the very best components in these cars. Got the leak fixed (core to headerplate soldered) Took out the waterpump impeller, thermostat, plugged rad core with solder peices that were floating in the tanks from a expensive lazy repair shop. That “condition” is that the factory radiator just isn’t up to the task of cooling while driven in a high-performance setting. How does a car radiator work? GM has actually came forward with a Special Coverage Adjustment in 20-2018 Z06 Corvettes that extends the warranty on the cooling system due to a “condition” that may cause overheating when driven on the track. One of the biggest issues I kept seeing was that the factory radiator is barely adequate for spirited street use on a stock Corvette, let alone anything that has been given power adders or racing duty. The forums and Facebook groups are filled with valuable information (once you weed through the hard-headed opinions) on what works for these cars and what doesn’t. While the C5 Corvette is a highly capable car out of the box, it certainly isn’t without its shortcomings once you start hot lapping on a road course.
