I cleaned my radiator , for the first time, last year. it was dirty but it was 8 years worth of dirt. now one year later my radiator is really dirty. What happened? Why is more dirt getting in now than before?:huh:
Hmm... I've had mine for about a year and never cleaned mine nor needed to I checked it out and it's still clean.. A few weeks back I cleaned one on an 89 for a forum memeber it dropped the coolant temp 10 degrees and raised the oil pressure a bit. (this one has an low oil pressure issue) so it's always a good idea to check it out and or clean it once in a while..
