running lean has been a though. cooling system is functioning at idle. and there is no reason it should not be. current collector is very small leak, i can't get a down pipe to seal correctly to the header due to the angle it's at. o2 sensors are cheep relitivly.

I have a small leak the the collector and another at cyl 6. Just replaced gasket and it's leaking again, header face is warped.

no i have not swapped to a zj clutch. It idles fine with or with out air. E fan cycles on for 5 mins at a time to get the temp down.

No dice on pulling block plugs and checking, can't get them out. Did flush the radaitor and block as best i could got some crud out but nothing major(some sediment and magnetic junk but coolant was still green). no luck. still wants to over heat. Whats average temp drop across the radiator on...

Replaced possibly suspect flowkool water pump with gates replacement. No change. It takes 20 plus min for it to cool down idling with good open. Flushed radiator today and will pull a block plug and check for sediment build up.

i have replaced the thermostat this week and been driving it. better, AC on in 65 degree weather and it will still get hot(230) but much later in the drive. No AC temps are stable at 195-200. yes it's a 195 stat.

my cat is a 1.5ish year old unit from magnaglow, replaced original ue to failing for high nox.

33 with 4.56

I will run the same test again with the cooler mounted vertical. What else should I be checking

mostly sustain 65 mph minor highway. today was very minimal traffic so basiclly sustained 65 mph only stopping once or twice and never for very long. All test drives have been the same path.

Another update, took it for a drive today after taking care of the exhaust hitting. First drive i have done with both engine and trans cold. also hottest today(70). Running with the air on, engine came up to temp and seamed to stay at 210, trans took a while to come up to temp, but once it...

i can watch the converter lock and unlock with the tach, hit the brakes and watch a 500 rpm jump. I did find a possible cause, my exhaust collecter was touching the block at the oil pan line. i've never been happy with the gibson header i installed, i had to grind the collector flange down to...

The head that was on the engine was a spare i swapped in years ago when i had a broken exhaust stud on cyl 6, it was easier to swap the head at that time with a low mileage rebuild unit from my spare engine. The head i just put on fixxed the coolant leaking issue from the hoses was the original...

Test-drive one , cleaned radiator condenser and coolers, removed ps temporarily. No discernable change. Test drive 2, removed grill and placed trans cooler on which mount flat, zip tied in place noticable change in temps. AC on 65 mph, 215ish engine while moving and 220 idle after drive, trans...

Temp creep underload is kind of what I'm dealing with. It will cool at idle but driving it down the road and it wants to puke it's brains out. It takes for ever to cool once parked. Trans cooler is already stand alone. It will get hot here, but in July August, it can get 90-100 here. Right now...
