Stock top radiator hose diameter

Awyman18 · 12-14-2011, 12:49 AM

So I'm installing a water temp gauge and I have to buy an adaptor but I need to know what the diameter of the top hose is? Any know the total specs?

Im doing the same thing and also need to know the size of the hose.

well that works for me lol i mean a little bit of a stretched hose wont hurt anything

just be careful, if the hose is slightly smaller, you can cut the hose while putting it on which will compromise its integrity. also, after heat cycling, if the hose is too small for the neck, it will crack easily and could lead to a premature failure.

neway, just be careful. good luck with it.

What's so hard about sliding a caliper over the neck as it leaves the end tank?

hey i have 88 supra do i need the fan for the radiator or can i get a radiator without fan because fan is so loud

Yes u need a fan it will over heat without it. If it loud then the fan clutch might be bad and is not releasing or u can switch to electric fans.

whats better electric or just leave it as is i also think there a air leak in exhaust bc engine noise over powers exhaust

If your fan is that loud the fan clutch fluid may be emulsified. Inspect the fan clutch. As for replacements, my preference is for lightweight, aluminum flex fans... They're mechanical, as quiet as electric (quieter than some electrics) and more reliable as they don't depend on additional sensors, relays and fuses. With modern mechanical vs electric fans, when pushing the same amount of air, the mechanical will probably be quieter as there's no additional motors driving it... It all depends on the design of the fan blades.
