About cooling system components

Standby sets in Kenya frequently run at high ambient temperature and dust loading, which puts the cooling system under more stress than the original design assumed. Overheating is one of the fastest routes to a destroyed engine, so cooling components are worth treating as critical rather than incidental.

What we supply in this category

Radiators and radiator cores

Reject engine heat. Blocked fins from dust and chaff are as common a cause of overheating as any internal fault.

Water pumps

Circulate coolant. Failure usually announces itself as a weep from the telltale hole or bearing noise before it becomes a seizure.

Thermostats and housings

Control warm-up and operating temperature. A thermostat stuck open causes chronic under-temperature running and carbon build-up.

Fans, fan belts and viscous drives

Move air through the radiator. Slipping belts or a failed viscous coupling cause overheating that looks like a radiator problem.

Hoses, clamps and expansion tanks

Contain the circuit. Perished hoses are a leading cause of sudden coolant loss on standby sets that sit idle between runs.

Coolant and supplemental additive

Correct inhibitor levels protect liners and cores. Plain water is a frequent and expensive shortcut.

Symptoms that usually point to this category

  • High coolant temperature alarm
  • Coolant loss
  • Steam or sweet smell
  • Set shutting down on temperature under load

Symptoms overlap between systems, so tell us what the set is doing rather than which part you think has failed — we will help identify it before you buy anything.

Prices are indicative and shown to give you a working budget figure. Landed cost moves with exchange rates and duty, so the current price is confirmed when we quote. Availability is also confirmed per enquiry — we do not ask for payment on a part we have not verified. Bulk rates apply on qualifying order quantities.

Parts Ordering & Dispatch

Order spare parts from anywhere in Kenya — you do not need to travel to Nairobi

Send us your generator details and we will confirm the correct part, quote it, and arrange dispatch to your town. We also supply parts for projects across East Africa on a cross-border basis.

Dispatch options

Bus & matatu parcel services

The established way to move parts up-country quickly. Parcels are booked to the stage or depot nearest you.

G4S and Wells Fargo courier

Tracked courier options for higher-value items such as controllers, AVRs and electronic modules.

Regional & local courier networks

Regional operators and local parcel networks where they reach your town more directly.

Your own transporter

If you already use a transporter or have staff travelling to Nairobi, we can release the parts to them.

The channel used depends on the part, its value and where it is going, so we agree it with you per order and confirm the cost before anything is sent.

Confirmed orders are dispatched the same day. How quickly they reach you then depends on the transport chosen — commonly a day or two up-country. We will tell you which channel we are using and when the parcel has been sent, so you can track it from your end.

What to send us so we quote the right part

Generator parts vary between builds of the same model, so we verify compatibility from your serial number before quoting rather than assuming from the model name.

  • ✔Generator make and model (for example Cummins C55D5, Perkins 1104A)
  • ✔Engine and alternator serial numbers from the data plate
  • ✔The part number if you have it, or the old part
  • ✔Photographs of the part, the data plate and the controller display
  • ✔Any fault or error code currently showing
  • ✔The town or county the parts should be sent to

Availability: stock changes, and some items are brought in to order. We confirm availability and price against your enquiry before you commit to anything — we do not ask for payment on a part we have not confirmed.
