How to Change a Thermostat @KenyanTraffic
Replacing a car's thermostat (or T-stat) is an easy and inexpensive repair, and in most cases will cure an overheating or no-heat problem, sparing the time and expense needed for expert diagnostics.
In most cases, the cause of an overheating or no-heat condition in your vehicle is a faulty thermostat. And since the T-stat price is only about Ksh 1,500, it makes more sense to replace it than to spend hours diagnosing the problem. If that doesn’t fix it, at least you’re only out about two hours learning how to replace a thermostat.
Pick up a new T-stat and gasket, as well as Silicone sealant, fresh coolant (to top off the system) and hose-clamping pliers at a car spare parts shop. Then gather up your socket spanner, a plastic scraper and a drip pan. Slide the drip pan under the engine to catch the spilled coolant.
The T-stat maybe located near the top of the engine under a “gooseneck” housing attached to the upper radiator hose. If yours isn’t there, consult your car user manual to locate it.
Here’s how to change the thermostat:
- Remove the two or three bolts that hold the gooseneck in place and remove the T-stat.
- Next, clean both the engine and the gooseneck sealing surfaces.
- If the spare parts shop gave you a plain gasket, coat one side with silicone sealant (self-adhesive gaskets don’t need sealant). Then install the T-stat and gasket.
- If the old T-stat used a rubber O-ring instead of a gasket, lubricate the new one with fresh coolant before you insert it.
- Reinstall the gooseneck and top off the coolant.
A car thermostat price ranges depending on the type of parts you need.
