Tip – most new water pumps come with a gasket, so you don’t need to buy one separately.You may need to get a slot head screwdriver behind it to jimmy it out, or it might just slide out easily. Remove the old gasket (the piece of metal which connects the water pump to the cylinder head).When the flow of coolant has slowed to a drip you can fully remove the bolts and take out the water pump.Removing the bolts entirely could cause coolant to spray out violently, so go slow and give the system time to drain before you fully remove the pump. Loosen the bolts on the water pump a little at a time to slowly drain the coolant.Before you do this, make sure you have a bucket in place beneath the car to catch the coolant/antifreeze when you unscrew the water pump. Slide it out gently, being careful to avoid turning the cogs. The belt should now have lost its tension and be easy to remove.This will loosen the timing belt, allowing you to remove it. Then, tighten the bolt to lock it in place. As you’re loosening the bolt, push down on the spring and move it downwards.Loosen the middle tensioner cog in the middle of the timing configuration it’s smaller than the two cams and will have a bolt on it.The cogs so you’ll be able to line things up correctly if anything slips when you remove the belt.The bottom cam, following the same process as above.The top cam, making sure the paint mark lines up with the top of the cog and the gasket.This will make reassembly much easier, as the cogs will need to realign perfectly to ensure good engine performance. Once you’ve done this you should be able to see the timing belt and water pump.īefore you loosen the pulley and remove the timing belt, it’s a really good idea to mark the cogs with a little white paint, Tip-Ex or chalk. You’ll then need to loosen a couple more bolts to remove the bottom timing case. This will reveal the crankshaft pulley, which you can now remove. Next, loosen the bolts or screws holding the upper timing cover in place.There are usually two bolts or screws holding the mount in place, one on top and one on the side. Now that the belts are removed and the crankshaft pulley is loosened, this should be a pretty straightforward job. The timing case covers the timing belt and water pump, so you’ll need to remove it. Follow the steps below to remove the belts: The fan belt and power steering belt sit beside the cover which houses the timing belt and water pump, so you’ll need to remove them first. Put the engine in gear (to prevent it spinning when you’re removing the timing belt) and engage the handbrake.Make sure the engine is completely cool before you start.Get all your tools ready and have bags and a pen to hand for labelling and storing parts you remove from the engine.Place a bucket under the water pump, as coolant will gush out when you remove it.Jack up the front of the car so you can access the undercarriage beneath the engine.Changing a timing belt and water pump can take anywhere from 1-3 hours depending on your skill level, so make sure you have the time and space to complete the job. White paint/Tip-Ex/white chalk (for marking the cogs for simpler reassembly)įirst, prepare your car and work area.Plastic bags and a permanent marker (for labelling nuts, bolts and parts you remove from the engine).Bucket or basin (for collecting coolant).Screwdrivers, including Philips and slot drive.What You’ll Need to Replace the Water Pump and Timing Belt We’ll walk you through the process of replacing a timing belt and water pump step by step, starting with the tools you’ll need.
