Customer Question

I HAVE A 1999 CADILLAC SEVILLE SLS. IN 1/10 OF THIS TEAR I REPLACED THE WATER PUMP AND THERMOSTAT. THE PUMP WAS SEEPING. SINCE I REPLACED THE PUMP IT OVER HEATED FOR A SHORT TIME . I CHECKED THE FANS ,THEY ARE FINE AND REPLACED THE CAP ON THE FILLER TANK AND PUT IN SOME OF THE SEALER TABS. THE TEMP GAUGE IN THE DASH WAS ACTING UP. ON MY NEXT OIL CHANGE AT THE GM DEALER THEY PUT AN INFORED THEMOMETERON IT AND THE ETC WAS BAD AND IT WAS REPLACED. WHEN I DRIVE AROUND TOWN THE TEMP IS NORMAL, BUT WHEN I GET ON THE HIGHWAY IT HEATS UP. ANY SUGGESTIONS. THANK YOU RANDY

these cars are notorious for head gasket and head bolt issues, i would have a combustion leak test performed to verify. There are several service bulletins on this issue

An enhanced thread repair process has been developed for use on General Motors aluminum engine components for the above listed engines. The thread repair kits used for this process represent a significant advancement in aluminum component thread repair, providing consistently repeatable high quality repairs which, when properly performed, will meet or exceed the original specifications. This enhanced thread repair process can, and should, be used to repair aluminum engine components, instead of complete engine replacement, whenever possible. Kent-Moore has distributed these thread repair kits to General Motors dealerships as part of their essential tool packages. The J 43965 Thread Repair Extension Kit has proven to be invaluable in the repair of difficult to access thread repair locations. Listed are the Engine VINs / RPOs and the applicable Kent-Moore essential tool thread repair kits.

Consult the appropriate applicable GM Service Manual or Kent-Moore thread repair kit for complete detailed instructions on the proper use of the above thread repair kits.
