Truck overheating issues

[NBui4]

So my 2000 Toyota Tundra started to have overheating issues. After driving it just a few blocks the thermometer goes in the red towards H.

Coolant levels are fine, fan is running, but I'm no mechanic.

Any suggestions before I take it in?

Thanks in advance.

Thermostat more than likely.

Sounds like a thermostat to me should be 2 10mm bolts and a$15 part and wa la good as new

You should defiantly do it your self a shop is going to charge you at least $200 and try to up sell u on a bunch of other shit like a flush, new belt, and maybe a radiator cap.

Might have to try that when i get some free time. Its my second vehicle so its not the end of the world but i definitely want to fix soon for hunting season.

Thanks for the suggestion

Overheating that fast, a vehicle that age could have a bad water pump.

Probably a thermostat like the others have said. You can check for coolant circulation by removing the radiator cap and running the engine to see if you have coolant flow when up to temp. Start with the cheaper route and replace the thermostat first. If that doesn't solve the problem, then it's probably the pump. Goodluck!

Get a bucket, drain coolant. Thermostat is on the lower radiator hose at the block. Remove lower hose at thermostat housing, remove thermostat, get splashed in face with coolant, replace thermostat, replace hose, replace coolant.

You are going to want the front end higher then the back end when you fill the coolant, it will bleed the air out better that way. It is NOT the fits everything coolant. Toyota Long Life, and it is pink. If the parts guy tries to sell you anything else dont listen.

What tmleadr said, don't reuse the old coolant.

+1 on the cap....Don't just change the thermostat.... change the radiator/fill pressure cap as well. I see more failures in pressure caps than thermostats. Without pressure you will overheat and boil rapidly.

The water pump is mechanical. The pulley seal will fail long before the pump fails (faulty seal will require pump replacement). Chances of a pump not pumping is next to impossible if the pulley is turning.

By the way as a shop I would also recommend a belt, cap, flush and water pump. Lol

While you're in there, just swap the motor.

+1. As you mention "When you get some free time" Working on a cooling system when it is 30 outside is no fun.

No, it really isn't. Nothing like being soaking wet when it is below freezing out.
