My son recently purchased a 940 wagon (1993 non-turbo, 176k miles)and I'm helping him get it road worthy for a move from Topeka to St Cloud. I noticed that the radiator had some seepage from the right side tank, so I thought it would be a good idea to fix it prior to his trip. I removed the radiator & took it to a local radiator shop. The proprietor told me that it was a replacement since it had brass tanks, and that is was too far gone to repair due to a large percentage of the fins being corroded away. I ordered a new radiator (Nissens), upper & lower radiator hoses, rad to reservoir hose, and a 92 deg thermostat and expect shipment later this week.

My question has to do with installing the thermo switch from the old rad & into the new. I am unclear as how it is held in position on the old rad (possibly a hex nut & a rubber bung)but I don't expect too much trouble there. But what about re-installation? I already have determined that prudence would dictate I install the switch with a new gromment - not a problem. Any tricks or techniques recommended other than boy butter & brute force?

Thanks for your time,

Joe in St Louis
