After screwing around with these new 12 amp vacuum cleaners that are far superior as space heaters and burn up real quick, been looking at used Electrolux vacuums that have twice the suction power, Made in the USA, and only draw 5 amps. Easy to rebuild.
Not the only space heater I have, those things out in the garage, even worse about 85% of the fuel I put into these things heats everything up, just a small fraction of my fuel dollar takes me some place. Point is, you have to keep your radiator and condenser clean and far more effective than collecting debris and insects than keeping the engine cool.
Turbo does help a little to recover some of that wasted heat energy, but not very much, around 2-3%, good thing our electrical power generation is a lot more efficient, couldn't afford to pay your electrical bill.
AC has created more problems offering more air flow restriction, normal high side pressures are in the 215 PSI range, with a plugged condenser, can shoot up to 400 PSI, puts a huge load on the compressor, that is also transmitted to the alternator, water pump, and tensioners with these crazy single drive belt systems. If that belt breaks, all that plastic and aluminum, like the head can crack, wasn't much a major problem when brass and cast iron was used, sure a problem today.
So worry a lot more about keeping that radiator and condenser clean more than anything else. Also frequently check your recovery tank to make sure its full of coolant.
How can anyone sell a vehicle with tires sticking out to spray road gravel on the tin, front fender, doors, rear bumper are all exposed. Found much better ones at my Fleet Farm store for ten bucks a pair, fit the Cruze, OE's are a way overpriced bad joke, as are K&N air filters.
