Overheating is the fastest way to wreck an engine — a head gasket can let go within minutes of the gauge hitting the red. Drova pressure-tests the cooling system on site, finds the leak (or the failed thermostat, fan or pump) and tells you exactly what's gone wrong before quoting.
Most overheating comes from one of four things: low coolant due to a leak, a stuck thermostat, a fan that's stopped running, or air locked in the system after a previous repair. Less commonly it's a head gasket or water pump — both diagnosable on the day.
If your gauge is climbing — pull over, switch off, let it cool, then call Drova. Driving an overheating engine costs four-figure repairs in minutes.
Diagnostic & pressure test £69 · Thermostat from £180 fitted. Coolant change £89, hose replacement from £95 fitted, water pump quoted after inspection. Written quote first.
Only briefly to a safe stopping point. Driving with low coolant overheats the engine and a single overheat event can warp the cylinder head — a £1,500+ repair from a £20 hose leak. Pull over and call us.
Three common causes: stuck thermostat (closed = no flow), cooling fan not working (overheats in traffic, fine on the motorway), or air locked in the system after a previous repair. All diagnosable on the visit.
If there's no puddle, the coolant is going somewhere — usually into the engine via a failing head gasket (mayonnaise on oil cap, sweet smell from the exhaust). A 5-minute combustion-leak test tells us yes or no.
Usually yes — a stuck-open thermostat means the engine never gets fully warm, and the heater matrix can't push hot air. Air locks in the heater core do the same. Both are quick fixes.
From £180 fitted on most cars, including coolant refill and proper bleeding. Final price by reg.
Same thing in practice — antifreeze concentrate mixed 50/50 with deionised water becomes coolant. Drova uses manufacturer-correct OAT/HOAT/IAT spec; the wrong type causes corrosion.
