I haven't done the same thing done on my 1,20,000 kms run figo. Will do it in the upcoming service. Also does this cleaning also increase mileage?
Best to get it done on the Figo too when time permits.
The intercooler fins will be coated in oil residue and the overall surface area available for the intercooler to work correctly will be reduced so indirectly the intercooler will not be able to work as required. Cleaning the intercooler at regular intervals say every 50,000 kms will help in the long run. On my Creta, I did the cleaning first at 35,000 kms and then at 75,000 kms.
The front bumper was removed to access the intercooler top mount bolts (as marked by the orange arrows)
Boost sensor to be removed
The intercooler (as seen from engine side)
Top plumbing - Clamp to be loosened to remove the pipe
Bottom plumbing - Clamp to be loosened to remove the pipe. Access this clamp from the top is difficult so the best is to remove the plastic cover underneath and access the clamp
Cleaning help for the DIY
WIP
Condition of the internals
I plan to do it again in the coming days when I get some time as the current odo is 1,26,xxx kms.
Overall after driving the 1.3L MJD engine in the Ritz VDi and Swift ZDi, one thing that I noted is the design of the intercooler plumbing also makes a lot of difference in 'how much' oil one would find after say driving for 50,000 kms.
