Engine Temp. runs *HOT* on Steep Hills!

:confused: :confused:

My VX engine temperature gets hot when I climb steep hills at a slow speed on very hot days. It stays cool when I am on the highways and when idling.

When climbing steep hills and turning on the heater; that is enough to keep the engine cool.

The engine has plenty of oil and coolent and runs great.

I cleaned the bugs off of the radiator coils to see if this makes a difference, but do not feel confident that it will make much of a difference.

Any suggestions?

Thanks!

Turn off the Air Conditioner.

Ron Davis Radiators now has the Vehicross template and will make you a double thick unit with trans cooler. They have also made a dual fan shroud so the clutch fan can be removed.
Cost about $1100 for both.
I had thse made for California driving, but have moved to Oregon and been too busy (And cool) to install.
Mounting a trans cooler with fan will take a huge load off the radiator. I was not able to find a good mounting spot. How about inside a scooped hood insert with the top or back of the scoop cut out?

I have seen the same thing on long, steep hills in warm weather. The needle goes from 6:00 to about 4:30, but never gets to a dangerously hot level. We have a small rad and a very small grille opening, so that may contribute to this. Make sure you're always in 3rd gear on a steep hill, or even 2nd gear if you're going slow enough. A lower gear places less load on your engine and allows it to run cooler.

... Water Wetter is product you add to your radiator that helps water flow faster and transfer more heat from the engine. Costs about $10 for a bottle of the red fluid. Also check the quality of your coolant, too much antifreeze can make your engine run hot. Keep the mix at 50/50 in the summer. Any less will not protect the metal parts from corrosion and may promote boil over in hot temps. Also consider flushing, and driving with the windows down and A/C off climbing tall hills in summer, and reduce speed and use a 3rd or lower gear while climbing. Hope that helps :luck:
