My Volvo has been having a problem where on "cold" mornings (I live in Florida so below 70 Fahrenheit lol) my car will just crank and crank. If I let go of the key it will backfire a little bit out of both the exhaust and intake. I suspect the head gasket because on one morning during one of those backfires I saw a small amount of smoke and a strong smell of coolant. I have been able to get it to start like this by cranking it until one of the backfires holds an idle with revs. It would also misfire sometimes intermittently for a while as I drove until it started to really heat up. Here's the confusing bit though, on warm or hot days, there's no problem it'll start right up and idle fine. So any input is appreciated, though I suspect head gasket because I've heard of cold start problems from coolant seeping through the gasket in the night. Also important is, I have overheated it on accident twice now after installing a toggle e-fan and forgetting to turn it on (I know) never in the red but definitely higher than the middle, also never a far drive maybe 5-10 minutes and no traffic so air was coming in. The problem only started after that so I may have warped the head, getting a 531 and gasket soon so no worries as far as the head but what are the odds I could've warped the block? Do red block blocks warp easily? Sorry about the long post, any input is again, appreciated!
