Fast and cheap Radiator Flush When I hit 40k mileages, I went to Bolsa Radiator for a radiator flush. I called ahead and ask how long it will take, since I had a lot of errands to run that day, and they told me 20 minutes. When I arrived to the time I left was under 10 minutes. When I arrived the man just took my car, did the flush, and went back to wrote me an invoice. The service was fast, swift, honest, and better than promise. I was very happy and would defiant come back again.
