Kevin: In addition to the spring wire retention there are other designs specifically to be used in cars that never had an OEM thermostat, or a convenient location in the goose neck to install one. The design that I’m familiar with is where a stainless steel T-stat is tack welded to a length of thin walled stainless tubing, and the whole mess is put into the upper radiator hose. If the T-stat is installed at the goose neck end the tubing works its way up the hose until a bend in the hose is encountered. It just sits there until you decide to change it. I’ve had the same one installed in my ‘Brand X’ for 18 years. I did put a good sized (#1 drill) bleed hole just in case the T-stat ended up at the radiator inlet fitting, which is likely considering the upper radiator hose is straight. dp
