Default Coolant Temp 3.3L - 05-18-2019, 02:15 PM

Looking at my coolant temp in the JB4 app, it seems to hover in the 213-215F range at highway speeds (75mph+), under low load it will drop to around 200F. This seems high to me but I wanted to know what other people are seeing...

I've noticed the oil temp gauge on the dash going up faster and higher than prior to installing JB4. This is a concern. Normal for the JB4?

I believe the temp that you see on the dash is trans temp.

Sorry, it was early in the morning and I wasn’t awake yet.

I see this is normal temps for the Stinger 3.3tt.

Of course if you're pushing the car it will generally make more heat so yes temps will be hotter, potentially, with tuning modifications. As long as you're not getting overheat warnings or coolant isn't spraying out of the radiator cap / surge tank, you're probably fine. You can always burp the coolant system for an hour or so to make sure there aren't any air bubbles trapped in there. After the dealer replaced my motor I was seeing high coolant temps and ended up having to burp 3 more times to get all the air out.

Also worth mentioning,I was able to lower IAT's and Oil / Coolant temp significantly by...

1) Installing secondary oil / coolant radiators from system-upgrade.co.kr
2) Wrapping my primary cats (not-stock) with titanium wrap
3) Wrapping my intercooler cold side / charge pipe (not stock) with fiberglass cold tape.
4) Bypassing the coolant line going to the throttle body.

@bal Any chance you can send me/PM me the steps on bypassing the TB coolant line?

Not much to bypassing the throttle body coolant line.

1) Remove both coolant hoses connected to the throttle body and from their connection points on the coolant rail.

2) Connect a new hose about 8-9 inches long between the connection points where the old hoses were on the coolant rail. You can use the existing pinch clamps (I used all 4).

3) Burp the coolant

I noticed something recently that when it's greater than 95F outside my average coolant temp drops to about 185-190F. It's cooled off since this happened the last time but when it warms up again I'll look for it.
