Topic: Kinpachi Overheated on Me Kinda

[Grimmjow]

If you guys have followed me I have a rebuilt 22re engine with a completely new top end. Last night when I got home from a long drive I noticed a gargling noise from under the hood. Sure enough it was spitting into the overfill. The thermometer never read hot, just normal operating temps. Well today I have been running diagnostics on it and may have found the culprit. When cold the fan clutch ha ssome resistance but when at op temp it free spins by hand. I would think its went bad on me. I did mess up maybe and stored it flat side down while the truck was down for a couple months. What are your thoughts? Thanks

Just ran a second test I found on here. It will hold a piece of paper against the radiator at op temp but I can stop and hold it pretty easily with a screwdriver.

Either one will work fine.

How new is the thermostat?

Are you running 50/50 anti-freeze with distilled water?

If your temp gauge is not registering "HOT"... something is wrong.  Hot gurgling coolant indicates the system may not be closed (leaking somewhere), could be bad radiator cap, and the coolant is probably above 200d F.

New thermostat Gnarls. I think the cap could be bad, I see how if it wasn't holding 13lbs it would release into the catch can. Let me buy a new one then update.

I like the release valve type.

Gotcha, I already bought just the plain Stanton lol. Well just noticed one more thing, while at idle my heat is a little weak but gets super hot while driving. Already checked the oil for water and its clean. Checked fluid levels in engine and there right on the money. Also no oil in water and no exhaust smoke or residue. I am pretty sure it puked the coolant out. I beginning to think my new water pump is garbage lol. I am getting a small squeak up front but I believe it's the adjustable idler pulley on the power steering belt. I will get one and see if the squeal goes away. If not it's the new water pump.

How many miles on the water pump?  A squeak is a warning!  Try to isolate and find the source of the squeak.  I blew my engine in 2013 because I thought the squeal was the pulley... it was the water pump and started leaking on the freeway.... toasted the engine.

Just FYI.... Also, running straight water is not a good idea.  Anti-freeze has a lubricating property (ethylene glycol), and I believe helps keep the water pump shaft lubricated.

Water pump is new. I do have 50/50 coolant. Since it's a new build I will check to make sure I still have 58 ft lbs on the head bolts as well. But before that I will do a leak down test.

Well since I installed the new radiator cap everything has been peachy. I dont think it was overheating before just pulling from a weak radiator cap coupled with a new water pump.

Well... sometimes we get lucky and it's a cheap fix.
