Aftermarket radiators fail to cure 2015 and 2016 Corvette C7 Z06 overheating problem

The super high engine operating temperatures for coolant and oil are by now the norm for the latest +General Motors flagship, Corvette C7 Z06.  Never before this generation of Corvette, coolant temperatures hoovering at 250+ and engine oil passing 300 F would become a common occurence for any of the "obsolete" Corvettes.

When overheating transmissions (both manual and automatic) and electric power steering are added to this hot mix, the seventh generation of Corvette has to be the lowest performance point in modern, past C3 Corvette history.

Is there a problem with cars running at 300+ oil temperatures?  Yes of course, just as much as there is with those super hight coolant temperatures, and not just from perfmance aspects but reliability and longevity of these cars as well.  Although as with anything else that is mechanical, these cars will take a shit sooner or later, it is the case of sooner being so much sooner than with the previous generations of the +General Motors iconic sports car.

In the typical ignorant and retarded fashion, the special olympics of addressing the effect without recognizing and understanding the cause continue with the attempts to cure the overheating problems.

Among the desperate attempts, there is coolant-water ratio solution, various seal removal and heat shield addition trials but nothing stands out more than the alleged "ultimate solution": a high capacity aftermarket radiator.

As already mentioned here, this is not just ignorant nd wasteful but super stupid as well, considering the high coolant operating temperatures are merely EFFECT of engineering problems present on the newest generation of Corvette.  Not only tackling effect part leads to no real solutions but it is also wasteful and potentially impacting the warranty coverage.

Apparently one has to spend 1200 dollars to learn this part the hard way since this is exactly how much Ron Davis radiator costs.  The results?  A total FAILURE, considering the extra weight gained for already heavy Z06 and oil temperature still easily reaching and exceeding 300F.

As already pointed out on this blog, without addressing non existent engine oil cooling and restricted air circulation under the hood (just for starters), anything done to the car will amount to a waste of money and effort.



Here is what happens when that supposedly magic remedy offered from Ron Davis is installed on the newest flagship: ABSOLUTELY NOTHING!!!



Yes, the coolant temperature is slightly lower but nowhere near a comfort level needed by someone stupid enough to take this newest piece of shit to the track.

  1. Is that steady drop in Max oil pressure normal? I don't think that is good, especially for the complex oil system on a push rod motor and even worse with DOD motor.

    1. It is normal for a car with oil temperature exceeding 300 degrees, LOL. Looks like the oil has not much viscosity left. I would be also concerned with that minimum oil pressure going up at the same time. Maybe another "defective oil filter" case, cough...

  2. The coolant temp is probably slightly lower because the reading was taken in September vs the initial reading taken in July. The radiator probably had closer to absolute zero effect.
