Hey everyone, I have a question and need some guidance. I’m trying to figure out how hot a car I bought for my son should run.
I bought the car for my 18 yr old son a few months ago and drove it 2hours home with no issue. While I was teaching my son how to drive a stick (doing stop and starts in a parking lot) we had the A/C on the car overheated. Well, the needle never moved from the middle of the gauge (190ish degrees) but I know the gauges in these things dont measure true temp. While we were practicing the starts and stops i saw coolant squirting about from under the hood at the passenger rear area and we shut it down right away and had it towed to the AAA i run. One of the plastic connectors on a heater core hose broke. I replaced both hoses and did 2 cooling system flushes to try and clean all the rust and such out of the system.
I have since been driving the car back and forth to work (about 3 miles each way) with A/C on I have been monitoring the coolant temp with both Dash command app and FORScan app and while driving if just cruising and not shifting gears the temp stays around 210 degrees. If Idling it will sit and Idle forever and sit between 198 and 212 degrees. But if shifting gears and driving its been as high as 224. When the temp gets that high I have turned on the heat and opened windows and gotten temp back down so i dont know if it will go higher in temp….
I guess my question is what true temp should these things climb to safely? I have changed to a 180 high flow stat and added water wetter to the 50/50 mix of coolant and nothing has changed.
any reason to be concerned here? I haven’t wanted to let him drive his car because i dont want it overheating and breaking down on him. So I have been letting him drive my car instead. But i would really like to get him in his 2001 and get my 2021 Gt back from him! Lol
