Does turning the heat on full blast slow down or prevent overheating?

 

This should be obvious, I think it's advised in owner's manuals typically.
Anyway, always run your econ fans in the hot position to aid cooling, it's not very nice for you ( or passengers) , obviously, but it does help...some

It helps, a little.

Think of it as your car's equivalent of taking your shirt off on a hot day...it helps, but not much.

 

In the HEATER position, the temp stays about the same at max, if not exact, but aims at the floor, and not on you directly, a nice option.
Also, I took the liberty of pouring some water on hand over my valve covers and manifold to aid the cooldown, while parked of course. I was able to continue a short distance in 15 minutes, I think.
This was after being stuck at a metered ramp for FAR too long and on a hot day to boot.

It helps as long as you have a working heater core. Coolant flows through the heater core and your blower fan pushes air through it, heating the air and dumping it into the cabin. This essentially works the same as your radiator, except smaller.

I would try to find whatever problem is causing your car to overheat, though.

 

My leak still seems quite small. I have some puddles form while hot, but after minor cooling the leaking from the block pretty much ends, at the same time, I keep checking the coolant levels but the radiator fans of my 89 are not running at all now... I'm trying to discern why.
For the leak, I lack money to invest in new gaskets and my friend suspects the engine and heads are warped. My mechanic suspects compression must be tested as well.
This is all alot of work for me, with my job hours shifting constantly this past year and wage being down more and more.
In this regard, after a new oil change, I'll put Prolong engine treatment to the test and report on results if anyone is wondering
