1991 BMW 525i Question: gsum to Greg's Auto...more on Heat Up Issue on bimmer
Greg's Auto...Question about total check of coolant system outlined yesterday in my request for help...I replied today to your suggestion about hydracarbons in system...I ment to ask you about the lack of heat up to the system's Rad return hose. System totally in play...ran engine to operating temp...about 210...checked the top feeder rad hose...it was about normal temp...Checked Rad return hose...cool no heat. However, when I disconect the return hose and run engine coolant flows through hose and heats up as the temp goes up in the engine while running...THE RAD RETURN HOSE REMINING COOL TO THE TOUCH HAS BE COURIOUS. Also, as noted in my first scream for HELP...With cooling system totally hooked up and the engine off...I opened the Rad Cap...squeez the feeder hose and it forces coolant out of the cap opening...I squeezed the lower return hose...the same happens it forces coolant out the Rad Cap as well....That tells me that the return hose and radiator are not blocked...Right or Wrong. gsum email@example.com - gsum
