\"2001Car overheats not sure why interior floor carpets damp maybe heater core Cadillac. It is a 2001 Cadillac Deville I checked oil, no water. I was wondering if heater core leak could cause overheating? Need Help Please.<\/p>\n

RESPONSE<\/p>\n

Yes, a leak anywhere in the cooling system<\/a> will cause an overheating<\/a> issue. Most likely reason for a damp floor would be the heater core leaking. Check your coolant level and if it is low, top it off and perform a pressure test on the system.<\/p>\n

I use a coolant system pressure tester kit. This will put an adequate amount of pressure on the cooling system and allow you to locate any leak in the system.<\/p>\n

            Installation Procedure<\/strong><\/p>\n

            Caution!<\/strong>\u00a0<\/b>Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.<\/span><\/p>\n
