‼️‼️‼️‼️We are doing a special for winter $1800 out the door tax and all other fees included on the ford 3.5 water pumps which includes a genuine ford timing chain and ford water pump, not cheap aftermarket parts. 2 year 24,000 mile warranty included. If you have a 3.5 ford engine with the internal water pump ran by the timing chain, we are keeping the ford pumps in stock now for those on the shelf at the shop!! If you have a ford explorer, edge, Ta**us, flex or Lincoln equivalent models then you more than likely have this water pump and it is not a cheap repair so come see us this winter to not have to pay double for it!‼️‼️‼️‼️

2013 f150 3.5 eco boost came in with a/c issues and intermittent no crank no start issue, compressor was starting to fail and starter had corrosion on the ground strap. Replaced the compressor and condenser since the drier comes inside of the condenser to ensure no debris gets into the new compressor and it was already out for inspection anyways so we just went back with a new one to be able to offer a warranty on the a/c system. New starter installed as well and got them back going. Give us a shout if you need anything!!

We are now offering transmission rebuilds!! Most will come standard with a 3 year 36,000 mile warranty on parts and labor but may be a longer warranty, just varies by transmission. Will come with new upgraded torque converter and valve body upgrades/ shift kits. Every transmission will be rebuilt with updated better parts to fix all the factory common flaws so you won’t have to be back in the same spot again. If you are needing any transmission work text 615-796-1409 or message the page. Thanks everyone!!!

2012 Chevy express 3500 van came in last week with some over heating and misfire issues, found cyl #8 plug wire not making contact with the spark plug anymore and spark plugs were fouled in multiple cylinders + the radiator had a leak. 99% of the time we only use OEM parts here! Got this one back going with a tune up with ac Delco plugs&wires , new upstream ac Delco o2 sensor passenger side along with a new ac Delco thermostat since it’s been overheating multiple times. Fixed the rear door that came off track as well temporarily until parts come in.

Big photo dump! 2017 Silverado 5.3 came in with a cylinder #7 misfire. Did some digging and found #7 cam lobe and lifter chewed up pretty bad. Pulled the engine and went with a DOD delete cam with ls7 lifters, new timing chain set, DOD delete tune, new oil pump that got destroyed from lifter material (in pics) all OEM gaskets to re seal the entire engine along with new oil cooler lines. Also while we had the heads off, we took all the intake valves out and cleaned off all the carbon build up to get better air flow back!! If you are needing something like this done give us a call or message us!!
