1965 CADILLAC FLEETWOOD

Typical onset: varies - age-related, typically 60+ years old

Symptoms: transmission slipping or delayed engagement, pink or milky fluid in radiator or transmission pan, transmission overheating, metal lines corroded through at fittings or along frame rail

Fix: Replace corroded steel cooler lines with new or upgraded braided stainless, flush transmission and cooling system if cross-contamination occurred, replace transmission filter and fluid. If coolant entered transmission, internal rebuild likely required. 4-6 hours labor for lines only, 15-20 hours if full transmission rebuild needed.

Estimated cost: $600-1,200 for lines and service, $2,800-4,500 if rebuild required

Symptoms: hard starting when hot, fuel smell in engine bay or garage, black smoke from exhaust, rough idle or stalling, gas dripping from carb base or air cleaner

Fix: The Carter AFB 4-barrel carbs dry out after sitting and needle/seat assemblies fail. Rebuild kit with proper ethanol-resistant components required, plus float adjustment. Many cars also need fuel pump replacement (mechanical pump on block) and fuel filter. In-line fuel filter add recommended. 3-5 hours for carb rebuild, adjustment, and fuel system service.

Estimated cost: $450-850

Typical onset: 80,000-150,000 mi or unknown history

Symptoms: deep knocking sound on cold start that may diminish when warm, low oil pressure at idle (under 10 psi hot), metallic rattling under acceleration, metal shavings in oil filter or pan

Fix: These engines are tough but improper oil maintenance or running low oil destroys bearings. Requires full engine teardown, crankshaft inspection and possible machining (often 0.010" or 0.020" undersize), new bearings, and careful assembly. Many shops recommend short block replacement or exchange given age. 25-35 hours labor for in-chassis rebuild with crank R&R, 18-22 hours for short block swap.

Estimated cost: $3,500-6,500 for bearing job with machining, $4,500-7,500 for short block exchange

Symptoms: clunk when shifting from park to drive or reverse, excessive drivetrain movement felt through floor, vibration at certain speeds, visible cracking or separation of rubber mount

Fix: Original rubber mounts are 60 years old and turn to dust. Replacement is straightforward with transmission jack support. 1.5-2 hours labor.

Estimated cost: $180-320

Symptoms: oil coating on valve covers and down side of block, oil spots under car after sitting, burning oil smell from exhaust manifolds, low oil level between changes

Fix: Cork gaskets harden and shrink with age. Valve covers are easy (1.5 hours), oil pan requires exhaust removal and careful scraping of old gasket material. Use modern rubber-composite gaskets, not cork. 3-4 hours for oil pan on these cars due to access.

Estimated cost: $250-400 for valve covers, $450-700 for oil pan

Symptoms: whining or groaning when turning steering wheel, steering effort increases, power steering fluid puddles under front of car, burnt smell from engine bay

Fix: Original pumps can cavitate and seize, hoses crack from age and heat. If pump runs dry it destroys itself quickly. Replacement pump, hoses, and flush of system required. Saginaw pumps are still available rebuilt. 2-3 hours labor.

Estimated cost: $400-750
