Well i found the source of my coolant leak (big crack)

[LordWayback]

That would scare me to death. Reheated plastic and thin spots. Maybe JB weld with a back up metal patch would work for me on that. But most radiator shops can replace the plastic tank for reasonable money, and the aluminum cores seem to hold up real well with good coolant maintenance.

1. California so any labor to remove and repair is far more expensive than just replacing.
I don’t do any long distance trips and I have unlimited distance AAA also if I don’t overfill the tank it doesn’t leak. however I still need to fix the pinhole just for piece of mind and I’m gonna add more filler plastic this is just to fill a time gap between a full cooling system minus water pump. also my fan clutch nut is frozen I have one that runs off the serpentine belt which needs to be taken off by a skilled mechanic I tried to replace the radiator in the first place but the thing stopping it from coming out is stuck because I don’t have a air hammer. NO MORE LOW COOLANT LIGHT/OVERHEATING FOR NOW

I guess you’ll see if it holds pressure huh? Fingers crossed.

I figured out that it only doesn’t hold pressure when I overfill it either that or my message center display burned out

I haven’t used coolant in this truck since I last saw Nicole in like june when my heater hose was still leaking it’s what caused it to crack, i was running a leaking heater hose for about a week while waiting for a new one and i overheated once really badly No head gasket blown just a cracked radiator tank

Be ready to cough up some big bucks, running just water in the radiator Is going to corrode the internal transmission cooler and get coolant in the transmission.

Some of theses suvs have two internal coolers. One for the transmission and one for the motor oil.

To be clear, the nut on the fan clutch is right-hand thread. There are air chisel marks on mine where some uneducated person tried to remove it in the wrong direction.

Oh I know only one I’m not able to change myself is the trans cooler if I have one

For the fan nut, put a large c clamp or c clamp vise grips on the pulley, clamping it to the engine. There’s one spot where you can do that. Then use a big breaker bar or breaker bar with a pipe over the end. That nut will come off as long as you turn in clockwise, reverse threads. Or an air hammer is $20 at Harbor Freight, just need a compressor or friend with one. Don’t let that stop you from replacing the radiator. Like was mentioned, if the internal trans cooler starts leaking, the fluids will mix and your trans will be destroyed almost immediately. There’s a few pics of using the clamp in this thread I linked.

How to install E-Fans

Step 1 - Pop hood Step 2 - Remove intake tube (This is only IF you want extra space...I didnt pull mine this time but you might want to) Step 3 - Remove two top bolts and pull coolant line clip out of shroud Step 4 - The Fan Shroud is two pieces. A top and a bottom. They are connected...

Hmmm. Pretty sure my AC Delco water pump had right-hand threads for the fan clutch. Right-tighty, lefty-loosey. Or am I wrong?
