Watching That Holley Sniper Digital Thermostat Like A Fat Kid Watches For The Ice Cream Truck. FJ40

This Holley Sniper is amazing. The best part is the digital screen which shows the temperature go up one degree at a time… the old displays just don’t stress me out the same way. Watching that temp climb slowly past the threshold is a damn nightmare. But, I think I’ve got the overheating fixed.

[@kenwalton1269]

According to the Haynes service manual, the thermostat doesn't fully open untill 203 degree. So factor in the +/- 10% rule, you have nothing to stress on

[@projectwrongway9127]

Solid words. It did get better and better.

[@takafumiarisawa70]

I'm drunk as sht and I thought that you were holding a steak @ 0:23 for a hot second.

[@arthurtzouros5622]

lol

[@projectwrongway9127]

Lol. You’re not that drunk…

[@mathiaslindstedt975]

Thanks for sharing these problems i hope you solve them. Love your channel!👍👏👏👏🤩

[@projectwrongway9127]

Love the support man, instant endorphins when the likes and subs show up!

[@michaelmacleod]

Love this little 40, its gonna be a tool once you get these little niggles sorted. lets see you messing with the 60!!

[@projectwrongway9127]

Gunning for a newish motor to get back in the fight.

[@cruiserkev1976]

Getting all tha air out is tricky. Drive it a few more times, any residual air will fart out into your overflow tank. 200 really isn't bad on a 100 degree day with a fresh radiator fill. Try driving it at night when it's cooler and do another temperature test, I'd bet the temps stay around 180 then.

[@projectwrongway9127]

True words. It got better and better each timeZ

[@arthurtzouros5622]

so glad your making these again.

[@projectwrongway9127]

Same. It’s a thankless gig some times but the comments and feedback keep it rolling.

[@normvernon1446]

200 isn’t really that bad - your timing can play a part as well - if you need more advance usually the engine will run hot.

[@bogotstogoskiing]

This! 100%. There probably is air still in the system but it's also possible turning the heater on moved the air out of the heating lines and into the block. It will eventually work itself out but the steep incline trick does work (like you did on the 60). I've had my FJ62 up to 230 before and it didn't damage anything before I finally fixed it.

[@projectwrongway9127]

It actually got better, and the more bubbles I got out the cooler it ran.

[@projectwrongway9127]

I’ll be doing that with the new motor.

[@lazlosfj40garage58]

After a long drive, my blue 78 hit 215 after I stopped - I did not know this as the temp gauge is t working.
My yellow 82 has a oil cooler standard from the factory and it never goes over 170. It’s a Land Cruiser thing - or a dirty old rad… probably the rad for me.

[@projectwrongway9127]

I’m stoked the new motor has a cooler, it’s in good shape so I’ll run it.

[@andrewkirk2488]

I had the same frustrating problem with my Fj45…I had a flush out system thingy you know with the yellow caps at the firewall well when I opened that up it burped the system and it’s been perfect for 2 years now… what a pain tho for a couple of weeks…Blessings:)

[@projectwrongway9127]

Going to use all the tricks once I put a new engine in. Good advice bro.

[@solrosenberg9924]

That temp fluctuation is nothing. It’s fine

[@projectwrongway9127]

It’s hard to listen to advice like this, but you’re right. Just need to drive it and work the bubbles out.

[@mattallengroupatREAL]

She’s just hot headed!

[@projectwrongway9127]

Rach has such positive feedback.

[@stoneshrink]

I swear it's a FJ40 thing. The same thing happens with the 350 chevy in mine.... I 'fix' it by briefly opening the valve to the heater.... temp drops, everything happy....

[@projectwrongway9127]

I’ll be pretty versed on cooling these by the time I’m done.

[@jameskellas6911]

The chain that was on that fuel cap (did you throw it away?) is meant to clip onto a springy pipe clip that holds the little rubber tube on that goes to the reservoir.

[@projectwrongway9127]

No, I’ve got it. Just got swept up in everything and forget to address that! Good looking out.

[@ryanknapp4964]

Where’s the sensor in the cooling circuit? It may have been dead headed then saw flow when you opened the heater valve. Either way it’s not in the same location as the thermostat so there will be some lag

[@projectwrongway9127]

It got better over time, everything started clicking.

[@paulsthormes251]

What kind of fans are you using? on my truck I'm running 6 blade plastic fan my engine temp 175 100 outside with air conditioning running. .

[@projectwrongway9127]

Same, I worked out a few more bubbles after the trip. I’m guessing that was it. Haven’t had the chance to run it long distance again but I’ll keep after it.

[@paulsthormes251]

@@projectwrongway9127 I did add something to my truck. It's called watch dog, it's came from Australia. It saved me when my truck overheated. It gives out a loud beeping noise. I was able to pull over Thermostat Went bad Save my engine .

[@projectwrongway9127]

@paulsthormes251 man I watch that temp gauge on the sniper like a hawk. I’d pay closer attention to that than the road!

[@dannyconelly1454]

Hold up... your Amp gauge works! no cruiser in the world has that!

[@projectwrongway9127]

Hopefully still does.
