For some reason today I decided to check the flow of my intercooler. I must say it looks weak compared to some videos I have seen. Looks like it's only flowing about 1 gallon per min. Sometimes it barely picks up flow. Can I clean the intercooler without taking it out. Any liquids I can shove in there. The Bosch pump only has less then 5,000 miles I would say. I think for the heat exchanger I can stick a garden hose and clean it out.
