Ive been fighting overheating issues on a 2001 cobra. When it first started running hot I limped it home and replaced the thermostat which solved the issue. Then a few days later when we installed a upr coolant crossover delete kit, now the car is overheating again. We vacuum bled the system but that made no difference. My main concern is that when we installed the coolant crossover delete kit we simply blocked off the thermostat bypass hose that would normally for other coolant crossover. Is this the main cause for our issues or could it be something else. Thanks for all responses.
