What’s wrong with my coolant system?

Replaced my coolant thermostat. Replaced coolant with regular green coolant. Drove it and burped it. Put more coolant in to “F” line on tank. Today the temp gauge got super high (see pics) and the coolant was literal boiling hot (see video)

What’s wrong?

 

Which engine, and which way did you orient the jiggle valve on the new thermostat?

 

Welcome aboard new member
Toyota coolant is red or pink

 

Burp it again. Prob. hung up in heater core.

 

Coolant level
leaks
fan belts
load on vehicle
air flow through radiator including fan clutch if equipped
coolant flow around cooling system.

for starters...

 

Radiator cap can also cause that. Make sure it didn't fall apart when you removed it. Seen that before.

 

Do these have electric fans or mechanical? When I replaced the thermostat on my corolla, I pulled the electric fans out to give myself more room to work. Whe putting it back in my switch didnt seat all the way so my fans didnt power up when needed.

Also, in general does your fan kick on?

 

Why did you replace your thermostat?
Is the reason you replaced because of overheating?
Could be any number of things

^^This,

 

What kind of coolant was in it before? Toyota red doesn't play nice with regular green. It's hard to get it all out. It takes a pretty thorough flush to get it done. If it had Toyota red in it before, you could have a mixture of the two types. Word is when they mix it makes a nasty sludge.

 

not sure if you can put the thermostat in backwards, so, did you put the thermostat in backwards i.e. spring pointing away from the block?

 

While burping did you have the heater on full blast in the truck? An air pocket in the system will back itself up against the thermostat until the pressure finally forces it open or it overheats.

 

You can install the t-stat backwards, I did it and caught it quickly

 

Cheap China built thermostat??

 

In to see what is up.

Just changed my radiator since I noticed a crack when changing the timing belt.

I put in a 170* thermostat as well. Didn't make any difference on the dummy gauge that I can tell.

 

Very likely it could be the jiggle valve. I installed the jiggle valve up on a T-stat and had overheating issues on my 3.4l. You would think the jiggle valve is properly installed at the 12 o'clock position since air bubbles rise but the correct orientation is at 6 o'clock. This is easily overlooked and caused my overheating issues last time I did a t-stat.

 

Why'd you replace T-stat? I had an old ranger i was doing preventative maintenance on, changed the T-stat and truck would randomly overheat. Put another new one in and my problem went away. Food for thought.

If your truck was overheating before as well, could be a number of things. Water pump, clogged radiator, clogged heater core ect. Start feeling Radiator lines and heater hose lines for temperature to make sure fluid flowing
