Make sure you installed the correct thermostat type. Should have the bypass blocking plate like this one:

Otherwise too much coolant will just recycle thru the engine and never make it to/from the radiator. Same problem with running this engine with no thermostat. Overheat.

The bypass design is supposed to equalize engine temps (hot spots) and allow early heater before engine reaching operating temps.
Hi, not yet however I did find that the 90 degree thermostat that was installed was faulty and was not opening. I removed that and took it for a drive and all hoses got hot and were same temp, which eliminates the water pump is a good sign, but the needle on the temp gauge stayed cold, on the C. Didn't even climb when the hoses were warm. Faulty temp sensor?
