Hello.

I have replaced the impeller with a repair kit due to overheating according to the temp meter, now it runs with temp just above the middle at medium and high speed, but on low speed it still goes to red on the meter.

If I want to replace the thermostat, do I need to remove the cylinder head and replace the cylinder head gasket or is it just the cylinder head cover that needs to be removed and then I can user permatex to seal it afterwards?
