So I uncovered the car and put the battery back in and did all my usual spring check list on the car before firing it up. All seemed well and she fired up without too much grumpiness. I took it out for a few laps around the block to get everything moving and flowing properly before going out for a cruise. Again all was well and everything was normal. Later on in the afternoon I loaded the wife and kids in for a nice cruise and heading down the road I noticed the coolant temps to be sitting in the 195-205 range and up to 210 at a stop light. Which is odd since last season it never went over 195 ever. Last season I flushedvout the block, put in a new aluminum 2 row 1" tubes rad and a prestone 180 Tstat, I had to bypass the heater core cause it sprung a leak. I have a new in the box TA 1537B water pump and was going to pick up a Mr Gasket 4364 180 Tstat and put them in today and see if that helps? How long do I have to let the gasket sealer set before I can road test the car?
