I'm replacing the radiator and thermostat in my '91 Nissan 240SX and have a couple questions:
For the thermostat, Nissan says to just use liquid gasket (silicone/RTV). However, several auto parts places sell a flat gasket part for this application. Which is better, the liquid gasket or the flat gasket part?
Some places sell a single model of radiator for this car, whether it's a manual or an automatic transmission. Such radiators have connections at the bottom for automatic transmission cooler lines which can be covered with rubber caps. My car is a manual trans. For my car, would a radiator with the auto trans connections be a potential place for leaking to occur, and would it therefore be a bad idea to use such a radiator?
Thanks for any and all advice on these topics.
