The car has a DRM stroker engine with the BIG radiator.
Was running good from a year ago.
The coolant temp was always between 185-195 with A/C on.

But recently I check and it is showing 210-220 with the A/C on in same condition as before.

I really don't know what's happening... I checked the fans and are ok, the change the coolant also. I'm using a low temp termostat. I also checked about some garbage in the front of the radiator. But everthing seems alright.

What do you think guys??
Does the termostat is not opening well or maybe the water pump is bad??

Need some advice and opinion on what to do to fix the problem.
Thanks!!

I would start with a call to DRM to see if they have a suggestion. If not, the thermostat would be the next cheapest place to start (besides the phone call to DRM). Do you have an undredrive pulley on the motor, and would this have an effect on the water pump output?

 

I just called DRM to tell them this problem. But they don't know exactly what's going on. So I post this forum to get different advices from you...
Do you think that the problem is the fan because is not pushing enough cfm to the engine or something??

Thanks!!

 

Here is what I did and I dropped my coolant temps about 30*.
Engine runs smoother, MPG has increased and I feel a slight bit more power and am sure I have less KR.

DUMP THE DEXSLUDGE.
Flush with water from a hose. Force into reservoir. Run water thru the system for 15 minutes. Allow to drain. Cap Radiator. Refill with Water. Start car. Bring to operating temp, depending on your Thermostat. At LEAST 170*, 180-190* is good. Let the water flush/mix thru the engine block. Turn on heat, let water run thru heat core and flush coolant in heater. Drain water. Cap Radiator. Fill with 1 Gallon Prestone Green Ethylene Glycol NO MORE DEXSLUDGE!! Add 1 bottle RedLine Water Wetter. Top off with 1.5-2 gallons DISTILLED WATER. Run car for 15-30 minutes whenever convenient. Let coolant fully cool. Check level and top with Distilled Water.

AWESOME results here. Before I was hitting 230-250 with the A/C on when stopped in the summer heat. I even boiled over the DexSludge once while parked w A/C on on the cell phone.

NO PROBS now. Car is soooo smooth. More Power too. Mildly, but you can tell the car runs much better.

Flush like this once a year in late Spring/early Summer.
I'd recc all Forced Inductions move to this setup.
If you have higher than a 3 Gallon capacity, I'd keep the Prestone Green at about a 30% ratio.

 

Thanks for your tip.

What do you mean with DEXSLUDGE??

Thanks!!
