    I have a 2007 Tacoma 4 cylinder A/T, with a small coolant leak. A few months ago my mechanic replaced the Radiator Hoses, clamps, Thermostat and thermostat housing gasket. But, the leak is coming from the R side of the thermostat housing area. It looks like there is a diamond shaped plate with 2 nuts that hold it in place. I have no idea what this is for. Sorry, no pics, it's pretty dark in there. I will add some soon. How do I go about fixing this leak?
