As a sanity check, first, does your temperature gauge work? If not, stop right there and fix it. I say this because you will need to keep an eye on it to make sure you don’t overheat the engine, possibly causing pistons and cylinder walls to score and the temper being taken out of the rings. Running an engine over 230 degrees F for extended periods can lead to boiling in the radiator, loss of coolant, and overheating the engine and ruining it. At the same time running the engine between 200 and 220 should help get rid of the carbon. Putting some kind of load on the engine will help too. I would also suggest that when you get ready to shut it down you open up the radiator and let it fast idle a few minutes to cool off.

Second, I never, EVER, recommend placing anything directly against the front of the radiator when there is a shroud of any kind around the fan. I say this from a bad experience my uncle had doing this. The fan broke a blade off and it went through the top tank of the radiator! Looking back and learning from it I figure it was due to excessive pressures on the blades (because they were not able to move air through the radiator) that caused the fan blade to break. Could have been a freak thing, but I’m not taking the chance. Covering the front of the grill is another matter entirely. This allows air to still move through the radiator keeping the stress on the fan similar to an open front, but still changing the air flow to come from the warmer area near the engine. Usually this is sufficient to bring the engine up to operating temp.

As one guy on this board so wisely said, posting questions here costs nothing, fixing something caused by lack of knowledge takes time and money, sometimes lots!
