If your temperature gauge is climbing, steam is rising from under the bonnet or the coolant keeps disappearing, MTS Garage Services in Hayes can find the cause before the engine pays for it.
An engine that runs too hot is under real threat. Aluminium cylinder heads can warp, gaskets can fail and in the worst cases the engine can seize. The advice is simple: when the gauge heads for red or a warning light comes on, pull over safely, switch off and let it cool. Do not open the cap while it is hot.
Engine overheating repairs Hayes drivers need usually come down to a short list of suspects: a leak, a failing thermostat, a blocked radiator, a dead fan, or a tired pump. Water pump replacement Hayes garages carry out is often part of the answer, and we work out which of them is really responsible.
Overheating is a symptom, not a fault in itself, so we trace it. A low coolant level points to a leak somewhere: a hose, the radiator, a heater matrix, a joint or the water pump seal. A thermostat stuck shut stops hot coolant reaching the radiator. A cooling fan that does not switch on may be a fan motor, relay or temperature sensor issue. A radiator can clog internally. A cap that no longer holds pressure lets coolant boil early. And a failing head gasket can push combustion gas into the coolant, which looks like overheating but needs a different cure. We pressure test the system and check for these in a sensible order rather than replacing parts hopefully.
The water pump circulates coolant round the engine. When it wears you may see a coolant drip near the front of the engine, hear a grumbling or whining noise from the belt area, or notice the heater blowing cold while the engine runs hot. On some engines the pump is driven by the timing belt, so the belt, tensioner and pump are sensibly renewed together, because the labour overlaps and a pump failure can wreck an old belt. On others it is driven by an auxiliary belt and is simpler to reach. After fitting we refill with the correct coolant, bleed trapped air and check for leaks.
A few sensible habits can save the engine.
We explain what we find, recommend the work and give you a clear estimate before repairs begin. If an overheating episode has already done damage, we say so and explain the options, which can include head gasket and cylinder head repairs, or engine rebuilds and replacement where they are warranted by the condition of the unit. We cannot promise outcomes before we have seen the engine, and we will not guess at costs over the phone. We work on cars and vans of all makes and models for drivers in Hayes, Southall, Uxbridge, Hounslow and West Drayton, so get in touch and we will book you in.

Only as a short-term measure once the engine is cold. Coolant does not vanish without reason, so there is a leak or a fault somewhere. Driving on with a low level risks warping the head or blowing the gasket.
It often means air in the cooling system, very low coolant, or a pump that is no longer moving the liquid round properly. It is a warning sign worth checking promptly, as it can come before serious overheating.
If the pump is driven by the timing belt, usually yes. The labour is largely the same, and an old belt next to a new pump is a false economy. We will confirm how your engine is arranged.
Yes, get it checked. A single episode can leave damage that shows later, and the cause rarely fixes itself. Look for white smoke, milky oil or a sweet smell, and tell us exactly what you saw.
