I have a Toy 4R V6 4WD 1995... Last winter I did not have enough anti-freeze and the water froze causing the engine to overheat. I was losing water about 2 litter evert 200 to 300 miles. Toyota diagnosed the problem and said its an external leak which means the water most likely is seeping into the exhaust system.
Since replacing the head gasket is a big and a costly job I was wondering are there any other parts that I should replace while the head is removed. Is it worth replacing the head gasket for a vehicle with 100,000+ miles on it. The truck is in a pretty good shape and the cost in Canada to replace the gasket is about $1300 canadian...
Any advise will be appreciated. Thanks Ken
