You can read my last thread but basicly my car was overheating. I bought the Mark VIII fan and now after 2 weeks the Mech said it wont fit even if he cuts it casue of the blower. He has no clue how to fix the overheating. Now I have 100amp alternator this fan and a car that I cant drive cause it overheats. I am sooooooooo PI$$ed. I really dont know enought to rip the car apart and start working on it yet. Does anyone have any good advice for what I should do.

Spoke to Neil earlier from this forum. He is going to help me work on my car. So sad people pay money to Mech and get nothing done. Its forums such as this that make it so much better. I thank you.

Good luck and keep us posted on your progess.

Sounds like a useless Mechanic there.. glad your getting the car back and help is on the way. If you want it done right.... do it yourself...

Any luk yet with your mechanic problems..?

There are a couple of inaccuracies listed either on this page/thread or a reference page/thread that I would like to address.

First,....coolant flow is KING when it comes to the efficiency of a cooling system. Yes....airflow is important too to be able to transfer the heat/BTUs to the "cooling" media...in this case air eventually.

Let's assume with your blowered small block that you are making at least 400 hp and maybe as much as 500 hp. Your stock radiator is just NOT enough for this combination unless you have huge airflow across the radiator at all times. The more air....the more efficient the radiator. But, you can have all the air across the radiator you want and if you can transfer it out of the engine fast enough then it gets left sitting there. So, either find a huge fan...or upgrade your radiator to a higher efficiency one such as a large-tubed aluminum one!

With that being said....a high flow water pump will be in order. Stock pumps are sufficient for several reasons. First...a blower motor is NOT a stock or "street" engine per se. Stock pumps are designed as "centrifugal" devices and with older style radiators with small tubes and high flow resistance....well there is a flow issue there as the system is not like new ....and these water pumps where NEVER designed to turn some of the rpms that are being hatched these days. Again...upgrade to a Stewarts or Tuffstuff water pump...both are excellent designs and will far exceed the "stock" water pumps. They also will perform under the duress of high rpms without cavitating and have closer tolerances which means they lose less pressure and "bypass".

I will absolutely guaranty that you will cool you system with these upgrades.
