Frank Carbone Posted September 7, 2005 Report Share Posted September 7, 2005 Hello all I've spent quite a few hrs replacing a waterpump on a 92 Seville 4.9L. The problem started when I noticed a leak at te pump housing near the firewall side of the engine. I removed all the bolts without issues except for 1. This is a 6mm bolt located approx. in the middle of the pump, to the right of the 2 Torx screws. It seemed to have broken with very little force and the head looked like it might have been streched when originally installed. (Factory pump never replaced). I tried to remove the remaining bolt with no luck so I tried to re-install pump without it by using some Permatex and some luck. Leaks like a tap! Cannot get a 90 deg drill to try and re-drill hole. Very frustrating as I don't want to spend a fortune to fix this but car is undrivable right now. Would appreciate any suggestions if anyone has some Thanks for any help Frank Link to comment Share on other sites More sharing options...

Would appreciate any suggestions if anyone has some Thanks for any help Frank I am not sure if it will fit, but try a Dremel tool, put a very sharp drill bit into it and drill a hole in the center of the bolt after a good center punch and use an easy-out, Mike I actually had the same problem Link to comment Share on other sites More sharing options...
Frank Carbone Posted September 7, 2005 Author Report Share Posted September 7, 2005 Thanks for the fast reply Scotty. I cant really get in there as the frame is in the way which makes it for no room to even get a dremel tool in there. All this over a 25 cent bolt!!!

Scotty Posted September 7, 2005 Report Share Posted September 7, 2005 Thanks for the fast reply Scotty. I cant really get in there as the frame is in the way which makes it for no room to even get a dremel tool in there. All this over a 25 cent bolt!!! I recently read of the idea to epoxy a piece of steel rod onto a broken bolt like you have letting it dry then slowly backing it out. You will need to make sure you only get it on the bolt stud. Try this site for some ideas http://www.devcon.com Remember this is a very small bolt, if you could cut a groove into it a screwdriver would work. If you can get a cut off disk grown down small you may be able to cut a groove into that bolt stud. You may need to remove the waterpump to get at it better. Consider this right angle attachment for your dremel tool http://www.dremelstore.us/drem575rigan.html Link to comment Share on other sites More sharing options...
Frank Carbone Posted September 8, 2005 Author Report Share Posted September 8, 2005 Thanks for all theadvice and links Scotty. I will look into it a bit deeper. I thought that I would make a plate with holes taken of the gasket and bolt it into position where the pump sits. The hole for the broken stud will be the proper size for a 6mm bolt so as to guide the drill straight and central to the position of the broke bolt. I think also will remove top torque strap and then loosen front engine mount which will alow me to hopefully lift the engine about an inch or two giving me access to use a drill and then retap the hole. Thanks again for your help and am very interested in reading about those adhesives. Frank Link to comment Share on other sites More sharing options...
Scotty Posted September 8, 2005 Report Share Posted September 8, 2005 Frank this epoxy looks promising, but if you can gain access by lifting the engine slightly to drill a hole for an easy out, that sounds better, Mike http://www.devcon.com/devconfamilyproduct....=177.0&catid=27 Link to comment Share on other sites More sharing options...
Frank Carbone Posted September 13, 2005 Author Report Share Posted September 13, 2005 Update. The pump is in and car is dry . I did not try the epoxy although now that I know of these produscts I'm sure they could come in handy. I ended up using the gasket as a template and I machined (I'm a machinest by trade) a drilling plate. I had to drill a small hole in the chassis through the wheel well and the plate guided the drill to drill out the broken bolt. It worked perfectly and the original threads were not damaged at all. Once the car was running and reached operating temp. I re-torqued the bolts again to make sure they were all tight. On the trip home the service engine light came on and OBD gave me an E041 code. and the drivers side power window was stuck open. I'm wondering if the car depended on this 6mm bolt. I fixed the window problem and found out that E041 is a camshaft position sensor problem. Is this the module located in the dist? also my tach has been acting up for many months now and am wondering if this sensor can be the cause. It seems to read 2-3X faster than actual RPM. Anyway I'm happy about fixing the leak and will now look into the sensor. Thanks to all that replied and offered help. Frank Carbone Link to comment Share on other sites More sharing options...
Scotty Posted September 13, 2005 Report Share Posted September 13, 2005 The camshaft position sensor is located in the distributor, see this thread especially page 3 http://caddyinfo.ipbhost.com/index.php?showtopic=5306&st=0 You will see that I helped dkedrowitsch with his distributor and learned that the distributor has the cam position sensor in it. There are some good scans also, Mike PS, glad you solved the water pump leak Link to comment Share on other sites More sharing options...
