Kind of hard to tell in this picture, but here's my intake manifold off, and valve covers still on. This was right before I pulled the original 3.4 for replacement when I hydrolocked it offroad.
A new radiator appears to have solved the issue! Now I'm hovering between 190-195 on a 100 degree day with the a/c on full blast. Thanks everybody for the help.
I'll replace it for the peace of mind if nothing else.
Since the ir thermometer is reading 190 or so on the coolant hoses does that mean the temp sensors are the issue? These are sensors from a jdm motor of unknown origins, using the stock harness from my U.S. 4runner
Fan clutch is a brand new aisin as of today. I burped the coolant system by having the front elevated and the heat on set to face and feet while adding coolant slowly. Temperatures at the upper coolant hose read 190 right out of the engine. And the bottom coolant hose reads 170-180 or so. The...
I am reading the temps through an elm327 obd2 reader using dash command on my iPhone. Sometimes the gauge on the dash reads higher than normal but not until about the 240 mark on dashcommand. I checked the heads with a compression test and all were reading 205 or above. The oil is not milky and...
What are the chances of both coolant temp sensors being bad. The one at the back of the block that controls the gauge, and the one at the front that goes to the ecu? These are sensors that came in a jdm motor I bought off of eBay. I've been chasing an overheating issue and am thinking the...
It ended up being the coolant line that hooks to the throttle body. It would leak onto the intake manifold. Park facing slightly downhill and it drips off the front of the engine. Park facing uphill and it drips down the back. Very deceiving leak but found it pretty quick once I started really...
I need help figuring out a coolant leak. It's a 3.4 jdm engine I swapped a few months ago. I changed the water pump and timing belt in the process, the old water pump looked good and dry but I put a new on in anyways. The leak is Above the water pump and wraps around the side of the engine, to...
Lol yeah I've got some bruises and scrapes from the weird ways I had to get my arm up there. Overall though I'd say it's like a 3-4 out of 10 for difficulty. If op is mechanically inclined whatsoever it should be a breeze. Or maybe I'm just used to working on stuff and I'm oversimplifying it? I...
I just swapped a JDM engine into my 97. I had to disconnect the tranny and torque converter to do so. Id say it was one of the easier parts of the job. There's 6 bolts holding the tranny to the engine, you can get to them easy if you have a lot of extensions. To disconnect the torque converter...
