Radiator cooler lines

[simonsayz1]

Radiator is 1 1/4" from rock auto, tried to find 1 1/2" to no avail, Trans fluid is full (checked a few times) and I've gone through a few clutch fans and all had same result. New one with new design does sound like a jet taking off, when I stand in front of the VX I can feel the air being pulled in (of course not when it's moving )...I'll check the Freon next

A few have switched to an electric fan with good results.

A few have had an issue with the AC compressor needing service. If it runs hot it's enough to heat up the engine bay to that point. I'll check and see what else...I know that there have been some recent discussions about this.

1 1/4" may not be enough based on what others have posted. Seems small but they spec'd it that way for a reason from the factory.

I have this high temp issue too. Something I have noticed when running the A/C is keeping the revs near 2500 rpms (65 mph cruising) will keep the temp gauge right in the middle. With the A/C off I can drive all day at 70+ mph no problem.

Well...it's not the Freon and I thought maybe ac compressor so I got a shorter serpentine belt and bypassed it, no difference.
Here's the odd part.....It actually runs cooler (almost normal) with A/C blasting and set at 75*

That's odd for sure...I keep going back to the radiator thickness...not sure about that but seems that is the one item that is different.

[simonsayz1]

Do you have a source that has a thicker one? Beside custom aluminum of course.

A few FB post say RockAuto or O'Reilly's have the right part.

Thanks again Mile High. The one I have is 1.25 from rockauto, I am running a wetter water but don't remember the brand

[Mile High VX]

OEM may still be available...try isuzupartscenter.com


Ask for Scott. He's always been good to me.

Online cataloge says it's about $550.

The RockAuto ones are all 1" or 1.25".

Have you tried any of the additives like Wetter Water...https://www.amazon.com/Red-Line-8020.../dp/B000CPI5ZK

The struggles of owning a VX...LOL.

A few have added a second fan but not sure that helps much at speed.

[Mile High VX]

Building those memories...I did the same with my boys. Using the VX as the canvas you'll never run out of things to do...LOL.

Not sure why they would do that...is it from a cold weather state?
