Radiator and cooling system repair covers the diagnosis and repair of everything that keeps your engine at the right temperature — the radiator, water pump, thermostat, hoses, and heater core — and it's exactly what our shop handles for drivers across East Rutherford and the rest of Bergen County. When a cooling system starts leaking, overheating, or losing efficiency, it rarely fixes itself, and catching it early usually means a smaller repair bill.
This page is the starting point for our cooling system work. Below you'll find a quick guide to matching your symptoms to the right sub-service, an outline of how we diagnose problems, honest NJ cost ranges, and answers to the questions we hear most from local drivers.
" "Cooling system problems show up differently depending on what's actually failing. Use the table below to match what you're noticing to the likely repair.
| Symptom you notice | Likely service | How urgent |
|---|---|---|
| Sweet smell, coolant puddle under the vehicle, or heater blowing cool air | Car Cooling System Repair | Soon — low coolant leads to overheating |
| Temperature gauge climbing, visible corrosion or rust streaks on the radiator, or coolant leaking near the front of the engine | Car Radiator Repair | High — risk of overheating while driving |
| Squealing or grinding noise from the front of the engine, coolant leaking from the water pump area, or engine overheating at idle | Car Water Pump Repair | High — pump failure can stop coolant flow entirely |
| Not sure what's wrong, just noticing occasional overheating or a warning light | Car Cooling System Repair | Moderate — have it inspected before it worsens |
Our mechanics start with a thorough pressure test and visual inspection to find exactly where a leak or weak point is, rather than guessing. Mike handles the engine diagnostics side of things, tracing overheating and temperature complaints back to the actual cause — a bad thermostat, a failing water pump, a cracked hose, or a radiator that's corroded internally.
Once we know the cause, we explain the repair options and what's actually needed, whether that's a hose and thermostat replacement or a full radiator or water pump swap. We check the heater core and air conditioning-related cooling components too, since they share coolant and airflow paths with the rest of the system.
Costs depend on what's actually failing. A pressure test and inspection typically runs $120–$180, thermostat or hose repairs run $220–$520, and a radiator, water pump, or heater core replacement typically falls between $450 and $1,200 depending on the vehicle. A straightforward radiator replacement on its own generally runs $500–$1,000, with hoses, clamps, and coolant service usually $120–$240. See /prices/ for our full price guide.
We're an independent, family-run, ASE-certified shop, and we stand behind every cooling system repair we do. Our team takes the time to explain what's wrong and why, instead of just replacing parts, and we service the surrounding Bergen County area with the same straightforward approach every time.
