My overheating problems started when my ’71 2000 SC overheated and deposited its coolant over the road via the radiator overflow tube. We diagnosed thermostat problems and drove home without the thermostat fitted which seemed to prove it.
After fitting a new thermostat the car was good for a couple of drives but then started overheating again. It was at that point I noticed a small leak at the bottom of the radiator. After reading up on possible clogging issues I bought Bars radiator sealant http://tinyurl.com/6gu7l2k as it is not meant to clog. I flushed out the radiator and the hoses (but without managing to open the cylinder block tap) and then put in the sealant along with fresh coolant and water. That appeared to work and after running the engine for a while a test drive worked out fine. The next day however the same overheating problem reappeared and the car once again threw out the coolant via the overflow tube. The new thermostat appears to be working as the top hose gets hot and cold.
I’d like some advice as to what to do now – do I buy a new radiator (I’ve seen one for £109) http://tinyurl.com/5wbf8uy or could the radiator cap be an issue and need to be replaced? Has anyone had any problems like this?
Any help much appreciated.
