    Broken fan - What Now

    The vast majority of those threads that I see, I post in to explain how ridiculous everyone is being. I have literally spent more time than I care to remember trying to get people to stop overreacting to what they dont understand when it comes to the hydraulic fan assemblies and the hydraulic...

    Broken fan - What Now

    Youre severely underestimating this. You need to build a relay bank, add all the wiring, fuses, and everything else. NONE of it is there. The G3 Viper was never designed for electric fans. The fitment of a G4 module should be no different. they share the same radiator. I would estimate 40-50...

    Broken fan - What Now

    Aint that the truth. FB has made it impossible to find any useful information. I still dont understand why its seemingly so easy to separate a customer from their money doing something they dont need, and then seemingly impossible to separate them from their money when it comes to properly...

    Broken fan - What Now

    CFM is not CFM when comparing a 10 horsepower fan to a pair of 1/8 horsepower. That said, if you are going to do it, the easiest method is the Gen4/5 fan shroud assembly. When you need to control it, let me know and we can reconfigure the PCM for relay control instead of hydraulic. I still...

    Broken fan - What Now

    You did what so many do, unfortunately. You replaced a small problem with huge problems, and paid a bunch of money to do so. Those aftermarket PS lines are known for failure, and the replacement fittings are known to cause PS PRV issues. Your original pump is surely fine, and your original lines...

    Broken fan - What Now

    1. That's because, by design, they are not up to the task. A real crimped hydraulic line and a stainless braided teflon are not created equal. The PRV in the pump should have prevented that possibility in both instances, and you also haven't excluded that the line fittings and PRV in the pump...

    Broken fan - What Now

    while I dont disagree, I keep coming back around to the obvious: There is no way the PS line should be able to rupture even with a capped end, that is the purpose of the PRV in the pump. So... defective line designs? bad pump PRV? plugged fan/bad PRV/poor hose quality...? I am betting there is...

    Broken fan - What Now

    For what its worth... there is a reason I shun aftermarket PS lines and pumps. Write down the EXACT chain of events and component changes, and the source of those components each time.

    Gen 4 Heads on Gen 3

    Short version: G4+ castings are as good out of the box as ported G3... but they do it better. All things being equal, you will require less cam and/or have better driveability at the same power in a G4 based car than a G3 based. The combination of head design changes, manifold changes and...

    Help! Gen 1 leaking engine coolant

    This would be the time to update all the gaskets. Give me a shout and I can get a package on the way for you.

    Slow cooling fan

    Good deal. Be sure to flush that system 58 times with ATF+4 to make sure its clean as can be, given it was apart for so long as has who-knows-what in it.

    Gen 4 Heads on Gen 3

    There has been numerous G5 manifold failures on TT builds. In high-boost cars they revert back to G4 manifolds... I think you may have been implying the same. Total cost-cutting measure.

    Gen 4 Heads on Gen 3

    The short version, is a lot of machine work on the heads, modified manifold and mechanical throttle conversion. Generally I wont go into exact details, because information has more value than the components... and a LOT of people, vendors included, arent even aware of the specifics and are...

    Running rough after a jump start

    Well, You're certainly right about that :) The fact that I sell and reman these modules, and yet tell people not to jump start... and then they dont listen.......... Does that make me a massochist, or them...? [well aware thats spelled wrong because this site blocks everything]

    Slow cooling fan

    There is also the chance that your pump has something wrong on the inlet side, and is unable to draw fluid from the reservoir. I have seen people assemble systems with dust caps still installed, and seeing as you dont know the history... who knows. If thats the case, you 100% need to replace...

    Gen III power steering

    If you start at "theres a 95% chance the dealer is full of shit" and go from there, you will probably be better off, ha. Also, they are NOT the people you want fixing anything like that either... they will create new problems. While its not impossible, rack failures are very, very rare. I...

    Gen 2 PCM issues

    PCM is dead. You would need to send it to us to see if we can recover it. Its 50/50 depending on when it lost connection. There is absolutely nothing you can do on your end, dont waste your time. We can also proper marry your SCT, which may be partially bricked mid-load as well. We do also...

    Gen 1 (94) Viper starting issues

    For what its worth, be very careful. When a PCM starts to become more sensitive than it should be with regard to battery voltage, its usually indicative of a pending failure. Normally this isn't a big deal... but seeing as G1 controller tend to fail catastrophically, it is a very big deal. I...

    Slow cooling fan

    The relief valve that would be the problem would be the one in the pump, not the fan more than likely. The relief valve in the fan is a bias valve to give priority to the rack when needed, and seeing as neither work properly... I am leaning pump. That said, you need to see if you are flowing...

    Bad computer/electrical issue

    If you mail your control modules here, I can tell you exactly what is going on and give you your options without any ambiguity about what is wrong or the quality of what you will receive back. $4500 would be stretch even if you needed literally everything conceivable.

    Slow cooling fan

    Its definitely tough to screw up, and yes, that routing is proper. That said, without having seen any of it, there is no guarantee its even all original... which could introduce who-knows-what problems if so.

    Slow cooling fan

    Look inside the reservoir with the engine idling. Can you see PS fluid moving/frothing? There is a good amount of flow in steady-state idle, regardless of downstream pass-through conditions. If you see nothing moving, you arent moving any fluid anywhere in the first place. That also begs the...

    Slow cooling fan

    Learn how to properly service it, use the proper fluids, and don't run into things... and you have a slim chance of that happening. But if you're hell-bent on Electric, just mix some ATF+4 and PS fluid together. That speeds up the failure nicely :smirk:

    Broken fan - What Now

    Blades ONLY. Shrouds of course differ, and motor configurations and valving also appear to differ between versions.

    Broken fan - What Now

    What you aren't factoring in, is that the same blade is used on all versions of the hydraulic fan, whether in a Viper or not. The other versions, are generally much cheaper, and all over the place. I wouldn't doubt if you could find one in your local wrecking yards.
