: water crossover

08-05-13, 10:02 PM
Looks like I'm going to have to do my water crossover. Does that Heal-A-Seal really work? I'm not looking forward to this one. Are there any instructions on how to R&R?
I have a '97 Seville:hmm:

Ive the steps. I'll post them with diagrams tomorrow.

What should be included in your toolbox is a fresh set of foul mouthed words, because you're going to use them alot.

Not a whole lot out there. Just told to get a rachetting end wrench and a whole lot of patience. There was a post that suggested on reassembly using rubber bands along with the bolts to hold the gaskets in place. Just get the bolts started and cut the rubber band.
I'll let you know if it works.

After 2 1/2 hours of trying to get the last two bolts by the firewall out. I sat back and wondered... How the hell am I going to get this back together and keep the gaskets in place? I do remember my Dad had a closed end end wrench with the perfect curves to get those bolts out. Remember this when your claiming your inheritance. Anyway, the Cadillac Forum Gods will not look favorably at me. I put it back together and added some Bars Leak. Cross your fingers. Hope you will forgive me.

Barsleak will only clog your heatercore and other passages, its not recommended by GM anymore...

i took off the crossover before i pulled motor out the top. why than? dont recall. could have waited till motor was out to remove it and heads but i think it was easier to reach bellhousing bolts with crossover gone. my memory is cloudy from that job. and i think i put motor back in and than put on crossover. double pain

FSM for my car calls for it to be pulled before yanking the motor out the top. If one drops the cradle there' s no need to remove it
