Coolant in Crossover Tube?

[Black*Death]

With the recent thread talking about a Cobra overheating got me thinking.

I changed my lower intake manifold and lost some coolant. I added some to the Degauss tank.


I decided to pull the threaded plug off a cold engine last night and there was no coolant in the crossover tube?

Is that normal? AKA the crossover drains after cooling?

Or should I warm the car up and add coolant through through the crossover?

I'd add it while it's cool and then run it through a heat cycle and check again.

The crossover is the highest point in the system and where you should fill it from.

Got it....I will add while cool and recheck

I would also recommend jacking the nose of the car up while adding coolant.

I had this problem after my eaton swap. It shouldn't be empty. Fill it up and stick a funnel in the crossover. Make sure the funnel fits snugly in the hole and fill the funnel about halfway up. When you start the car bubbles will start to come up through the coolant and the level in the funnel will drop. Make sure it never goes empty. After the car has run for a while and got hot suck the extra coolant out of the funnel, cap the crossover and you're done!

Also squeeze the bubbles out of the radiator hose. It will just help speed things up.

Just remember to shit it down when the fans kick on. Leaving it on too long can become a problem as well IIRC from the Reische t stat site.
