Bruce Nunnally Posted April 15, 2013 Report Share Posted April 15, 2013 First question, can you tell more about what is going on with your Cadillac and why you think you need to remove the water pump crossover?

KHE Posted April 15, 2013 Report Share Posted April 15, 2013 No - you do not need to remove the trans. to remove the crossover housing. The R&R of the crossover housing with the engine in the car is a royal PITA though.

BodybyFisher Posted April 17, 2013 Report Share Posted April 17, 2013 I agree with Kevin, R&Ring the crossover is a very difficult job. A lot of stuff gets into the way of getting to the bolts and getting it out. An electrical conduit, the PRND21 switch module, water pipes, the throttle body. Very time consuming job. But it can be done just take your time. I removed the entire electrical conduit that connected everything as far away as the oil level sensor, the relay center, the PRND21 module, throttle body, and it was still a biaoch to get at the bottom bolts. The old seals were a mess its no wonder mine were leaking Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
Papalac Posted August 4, 2018 Report Share Posted August 4, 2018 I see that this post is a little bit old but what the heck_the job will probably make you cuss but very doable-going to have to do it on my 02 eldo , I can see the residue around the gasket from looking down thru the mess-not experienced enough to know how to get that darn wire harness out of the way- Link to comment Share on other sites More sharing options...
BodybyFisher Posted August 5, 2018 Report Share Posted August 5, 2018 You have to work around the wiring harness. I will search for my crossover thread and post a link to it.
