Stock top radiator hose diameter
 

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.

i believe its 1.25". or just under that.

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?

a caliper?

That's a joke, right?

and its official, 7 days and 5 hours of sleep is starting to take its toll. no, wasnt a joke, i wasnt recognizing the context. yes, that would be a grand way to determine the outer diameter....

then again, if they had a set or could get their hands on a set, then i dont think they would be posting the question here.

I hear ya on the sleep thing... I'm sick as a 1000HP Supra right now and despite needing sleep desperately all of my symptoms have prevented it for days... :wtc: That and I'm also an insomniac.

You can get a plastic one at Harbor Freight or many hardware stores for a buck or two... So I'm going to assume that they A) didn't think on it B) aren't able to get to the car or C) are just being lazy. ;)

im lazy :) lol but im currently holding in my hand as im typing with one hand, a 32mm adapter. and im about to install it in the next hour, so ill let u kno how it goes

radiator
 

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.
