Cooling issue ultimately was a full head gasket job, plus repairs to the radiator. There ended up being a gap about 2 millimeters thick between the head and the block. Had to replace the head of one side. Also needed emissions repairs. Emissions system failing to properly work. Suspected issue with catalytic converters. So far we've tried running through several tanks of Shell gas as it has the most detergents in hopes that it would be cleaned out. No luck with that so far. Next step is replacement, that will be done in the next month or so.

138000 mi US $2000

So we've finally come to the end of a long Odyssey. No pun intended. We ended up taking the vehicle to a new mechanic who removed the entire engine, disassembled it and cleaned it, resealed the whole thing. Reinstalled it and it's running better than it has since we first purchased it. It cost about $2000 dollars, but the work is completely guaranteed and the peace of mind for our family is worth it. Only piece of advice I have, get a second opinion on work done by a mechanic who's not completely up front with you.

Water pump was squeaking. Replaced water pump with OEM Toyota pump, as well as OEM Toyota thermostat. Old water pump gasket came apart and took hours to remove old material from engine block. Previous owner had a mechanic install a non OEM Toyota water pump which uses a felt gasket. Bad choice. Replaced bearings on serpentine belt pulleys and tensioner.

198000 mi US $35

Vaccum lines running to airbox were split and worn. Replaced vacuum hoses as well as installed new OEM Toyota engine air filter and Denso cabin air filter. I recommend only Toyota OEM engine oil filter as other filters don't fit well and aren't much cheaper.

155000 mi US $10	Replaced both valve cover gaskets due to oil leak . Replaced spark plug seals at same time as they were brittle. I replaced the fire wall coil packs , even though they were functioning, as a preventative measure since they are difficult to get to and the job of renewing the valve cover gaskets involves removing all that was necessary for the coil packs as well. The packs at front are easier to access if need be.
159000 mi US $600	Torque strut mount (dog bone ) replaced as well.

116700 mi US $25	Check engine light on. Scanned it and it came up evaporative emissions system. Replaced the fuel cap which did not fix the problem. Van runs great, will eventually check all hoses for leaks.
