Hi mate,
Although usually engines exposed to cold weather is the most known problem related to car starting difficulties, hot engines might bring obstacles as well. Many people realize that the car does not start as easily as it should when the engine is hot and do not know what to do about it. In order to be able to overcome this problem, it is important to start by learning why it happens.
Most of the reasons by which a hot engine would be hard to start are based on problems related to the fuel. When the engine is too hot, fuel can't circulate properly due to the way in which vapor obstructs it and therefore the engine wouldn't start as easily as it should or it wouldn't start at all.
A car engine would keep on gaining temperature until a while after it was shut off. During this period of time is when the highest amount of vapor would be circulating around and therefore that is when the chances it obstructs the engine are bigger as well. This way, if you are driving in hot weather and you have just turned off the car in which you experience start problems, you should wait for a few minutes until starting it back.
Fuel injected engines do not experience this problem as much as others do due to the fact that the fuel remains inside the injectors by being under a very high pressure. This way, fuel injected engines would not become so easily obstruded by vapors as other engines would and therefore the car would not have the same problems to start as another would.
Also, engines might become hard to start while being hot if it coincides with the season in which refiners change from one fuel blend to another. Sometimes gasoline refiners change from a higher volatility fuel to a lower one when summer approaches due to the way in which hot weather causes fuel to evaporate easier. If refiners change back to a higher volatility fuel while the engine is still exposed to days of high temperatures, this could cause the fuel to evaporate too much creating too much vapor and therefore obtruding the engine.

How to Repair Cracks in a Dashboard
Written by Doityourself Staff on May 28, 2010 Reviewed by H.R. Helm on May 28, 2021
A close up on a dashboard.
What You'll Need
The dashboard of a vehicle gets a lot more abuse than people realize. Dust and moisture rapidly accumulate on the dashboard. Whenever you run the heat or the air conditioner you are subjecting the dashboard to those temperature changes.

The sun is the most damaging of all as it shines down constantly on the dashboard with its rays being magnified by the glass. And if you also factor in using the dashboard as a drum set at stop lights, it is no wonder the vinyl cracks. You can take the vehicle to the local mechanic or dealer to have it fixed or replaced or you can do it yourself. This article will show you how to repair a cracked dashboard with inexpensive materials and wasting very little of your time.

Step 1 - Prepare the Dashboard
To ensure a strong bond the dashboard has to be clean. Wipe it down thoroughly with a dashboard cleaning rag. In order for a crack to be properly sealed it needs to be level. Use a utility knife to trim away parts of vinyl that are peeling away from the dashboard or are curling.

Step 2 - Deal with Small Cracks
These are the easiest to repair if you get to them fast enough. You will need to use a paintable silicone. Not all silicone caulks are paintable. Fill the crack with silicone caulking and allow it to cure. It is a good idea to apply silicone in at least two layers. You want to inject enough silicone to fill the crack and not to just fill it on the surface. If excess silicone appears above the crack, simply wet your finger and smooth it out. When the silicone has dried you can cover it with vinyl tape and then paint and blend the edges with the proper color.

Find paintable silicone on Amazon

Step 3 - Repair Large Cracks
If your dashboard is heavily cracked, then you need to take severe steps to repair it. Fill the cracks as much as you can with silicone caulk as you did in Step 1. An alternative to silicone would be a two-part epoxy solution or other industrial filler. This depends on the size of the crack.

Fill the crack so that the filler overflows slightly. Smooth it out with a wet finger. If using epoxy or metal filler, then sand it down. Cover the top of the crack with fiberglass resin. This will create a very strong repair due to the interlocking fibers. Let the fiberglass resin cure completely and then apply bondo over the fiberglass. This will fill in the voids found in the woven
