Overheating issues

Before you go off half cocked and do a bunch of work that won't matter, measure your pulleys. The water pump MUST turn faster than crank speed. This is the number ONE issue that causes overheating. You can build this and fab that, but you have to have the basics correct first. And water pump speed is basic number one.

The water pump pulley must be SMALLER than the crank pulley. I'm betting yours isn't.

Start there first. Buy a QUALITY, high flow thermostat so it's not any more restriction than it has to be. Flow restriction is bad. I buy my high flow thermostats from Stewart Components. They are more money, but they work.


There is more than one thread on here about water pump speed and how it fixed overheating issues. I don't use a shroud on my car and it won't get over 185ish at a stop light on a 105* day. At that same temp is will cruise at 170ish.

Measure your stuff and see what you have.
