  Q: How Do You Install a New or Reconditioned Cylinder Head, Including Fitting Coolant Hose Outlet Pipes and Valve Components on Toyota Echo?

  A: If a new head is being installed and coolant hose outlet pipes are missing, get new ones. Apply adhesive to each pipe's bottom end and press the radiator hose into the cylinder head 15 mm deep, and the bypass hose pipe 18 mm deep. Mark the correct depth on each pipe, then press each in squarely with a hammer and wood block. Reinstall all sixteen valve spring lower seats. Lubricate the valve stem oil seals with engine oil and push them into the cylinder head using a socket. Lubricate the valve stems and insert them, ensuring not to damage the oil seal. Fit the valve springs and upper seats, compress the valve spring and locate the split collets in the valve stem. Repeat for all valves. Tap the end of each valve stem to settle the components. Refit the removed components.
