Question about heater core removal

Ok. Thanks guys. Update. I still havent fixed it. The engine runs colder without bypass. But 11$ in coolant every 3 months is ridiculous and the fumes lol. As you would expect. 163,000 miles now, but god damn i live this jeep. The pressure calculations are for overflow of the coolant for whomever asked. Heat and less fluid and less circulation means more pressure. More pressure results in corrosion. Anyway. I try my best with it. I try to know everything about it. Im quite capable but resources for self care of vehicles are almost dried up in the real world and guys like us are going extinct.

Pressure in the cooling system is controlled by the radiator cap, bypass the heater core fill with coolant bleed air out and drive it

You live in a cooler locale. Try only putting your radiator cap on the first notch. The pressure will be next to nil and should prevent the fluid from eeking out (if it is a real small hole) until you can fix it properly. You will also need to check the fluid IN the radiator as the syatem will not be utilizing the overflow jug to keep it full.

It will leak with the cap on the first notch

It should only leak the amount in which the coolant expands. Once the initial has expanded out it shouldn't leak anymore.

The first notch seals it with a few psi, not 18. Done this several times in my youth with the crappy cars I owned. Learned it from my uncle who owned a car dealership. But I will say I have not done it with a jeep. Nova, Escort and Dakota, check. Also had a fleet of trucks a few years ago and I had the guys do this with F-150's until they could get them in the shop. I will say, the F-150 is a bit different because the pressure cap is on the overflow jug, but still worked.

Yep. Way back when, before vehicles had overflow / return tanks, the radiator just overflowed through a hose onto the road. The side tank on those radiators were marked with a FILL line about 2 inches from the top to account for the fluid expansion. If they were filled above that mark, they would expel the excess fluid after driving for a while.

The good ol days
 
@bohuggabee , You can just do a radiator bypass and plumb the waterpump output right back into the waterpump input.
That way, the water won't leak anywhere and you can probably reduce drag due to the lower volume and the reluctance of the prefabulated amulite.
Give it a shot, I did and now I get 44 MPG and don't have to buy coolant anymore!.

You're a braver man than I, Mhass. I would never bypass the radiator without a Fetzer valve in the bypass line to prevent off-axis combobulation. You're lucky your rig didn't suffer a discombobulation event. Messy. Very messy.

Normally, I'd agree with you. However, it was a field fix, and after that I did the math and had @Wranglerfix add Rockwell software to my CPU, allowing the use of cardinal grametes to automatically synchronize my phase detractors.
Testing has shown this to be an effective safety measure and even adds to the fuel efficiency through molecular phase bonding.
 
You all are all wrong. You really need to get a flux capacitor. 100 mpg. Proven fact. Look it up. Everyone with a brain knows this. Driving with a flux capacitor is like having more time…..

Flux capacitor? Wow, real nice. You probably think you're SOOOO funny.

We obviously need a flux inductor. We want our voltage to lag our current, duh. More voltage = more current = hamsters spinning too fast. Maybe add a resistor in parallel, get us a flux low pass filter. No high speeds here, not too fast, that keeps the hamsters right in their efficient range in my shitty 2.4 liter. 150 mpg all day long. You can sit back, shitpost on YouTube, and smoke that Colorado weed the whole commute to your 4 hour shift at GameStop.

It's basic mechanics, c'mon now.

And don't forget your Aeon Flux also! Add that to the flux capacitor and you will probably double that mileage.
