Okay so I've 75% solved this problem.. I flushed the heater core again, using hot water and a drill pump, in both directions (put about 5 gallons through). I blew it out with 30 psi compressed air between direction changes... Filled it with CLR and let it sit about 2h. Then i set up a...

Oh man that's great news.

Yeah I know I'm asking in the wrong season [emoji14]

2004 4runner sport v6 4.0L. I get heat only on the driver's side of the cabin - the passenger side blows cold. A/C works on both sides. I've tried flushing the heck out of the heater core.. Any other "low hanging fruit" explanations? Much obliged, Kris

That's all it was! Forgot to update :) thanks

Fan clutch engages fine, coolant overflow tank had no leaks and hose was not clogged.. These good suggestions were some of the first things I checked. Just to update the thread for anyone else with similar issues that should stumble across it, I replaced the radiator with a new oem part from...

Nope, doesn't seem to overheat any other time. I'm guessing the cooling system just isn't up to the task with the combination of the heat from the tranny on a long high 75 mph highway drive, plus "hot" weather (84 degrees F, Canada hot :)). That's a good point about the AC condenser "comb"...

Update : got ahold of a block tester kit.. No exhaust in the coolant, even after a long trip. Thank God... I think it just boils over on a long highway run because the rad isn't up to the task.. No leaks in the system. So i may just replace the rad (it's still on the original), flush the...

I mean could anything besides a leaking HG cause this?

Just 130k miles. It never got all the way to the red before i pulled it over, but close.. This problem is what caused that incident though.. Again, only showed up after hours on the highway.

Yeah so got home last night from the trip and let the 4runner cool until now (about 20 hrs). When i removed the rad cap it was still pressurized.. And it smells like exhaust. Aaaaaargh

Thanks for all the suggestions guys.. I'm having a hard time understanding how the T-stat would cause this, as the cooling has been fine all the rest of the time (non-long highway trips) and the path for fluid from engine to the rad is obviously open if the coolant is being pushed into the...

Hey thanks a lot for the reply preacher :cheers: Well, the previous owner replaced the thermostat not long before I bought the vehicle.. both the top and bottom hoses from the rad are hot when she's at operating temperature, and in regular city driving (stop and go, shorter freeway drives)...

I wonder if i could get some opinions on this - recently took my 04 4 runner (4L V6 1GR-FE) on it's first camping trip with me as the owner.. After a couple of hours of highway driving, after a coffee stop, had high temp problems.. Turned her off at a hotel parking lot just before she got...

Maybe the solution to this is too obvious or something, hehe :) I found this "Mr. Gasket water pump pulley shim kit" for sale, Mr. Gasket 6129 Mr. Gasket Water Pump Pulley Shim Kits - Free Shipping on All Orders @ JEGS I guess I can just take off the pulley and shim it up with that.. Can you...
