Default Oil thermostat bypass - 01-25-2013, 02:57 PM

Hey guys,

We've been testing a thermostat bypass for the last couple of weeks on two of our development cars. It's easy to install and allows oil to flow through the oil cooler full time, rather than only flowing through when oil is > ~240 degrees.

I did a series of cold start warmup tests and oil warm up time went up only around 45 seconds. But during warmer weather back to back runs oil temperatures were consistently 15+ degrees lower.

It's one of those inexpensive and easy to install mods. Worth playing around with especially for those of you in warmer climates.

I've only been able to test it down to 50 degrees but as I said no issues there. We'll have to see how it does with 20 degree weather but I don't expect any issues other than a slightly longer oil warmup.

Send one out if you need cold weather data. Single digits in the am & 20's in the pm.

Look forward to testing this out Terry. It was 110 degrees Fahrenheit here one day last week.

It was -15F here this morning and it took my oil 20min of highway driving to get to 160 (jb4 to kick in) then it only got to ~200 by then end of my 35min drive to work. So it might be a bad idea to use the bypass in colder climates since you do want your oil to be around 212 at least. But hotter climates this bypass is going to be good. Terry how long on the install?

Takes no more than 10 mins. Two bolts is all that holds the T-Stat in there.

I would assume its reversable like for winter time? I would use it here june through august then go back to stock for winter.

Yes easily reversible. Takes 5min to install.

If you have a consistent warm up time in that winter weather it would be interesting to see how that changes with this. In 50-60 degree weather here I noticed barely any change.

Assuming user's have the basic understanding of how oil temps can affect turbo's and turbo life then this is yet another great little mod for all.

is there a way to machine it so the oil cooler kicks in at say 200. This way the car will warm up normally but stay cooler. Also does this bypass make the jb4's warmup safety ineffective?


Always listen to experts. They'll tell you what can't be done and why. Then do it.

This is all we offer. But the warmup has not been much of an issue in testing as I mentioned. Has nothing to do with the JB4. That stays off until 160 still.

No i dont think you will machine it down because a thermostat consists of a special interior that melts inside and pushes the spring open. Youtube "thermostat" and see how they work and how they are made. Very interesting.
