water pump oddity
I was driving home from lake havasu in az and a new ago I replaced the water pump but today when I was accerlerating up the hill it started to get hot like the water pump wasn't flowing enough water and the engine would sound like a diesal. but when it went flat it ran normal any opinions

the coolant was topped off the radiator is new its the 2 core from ipd the theromastat is new along with the hoses they were all done 6 months ago when I was driving around the temp gauge was running cool and as I accended the gradual 35 degree hill the temp started to climb and I pulled over shut it off before it got in the red. When I got home lastnight I did notice that the after market water pump had a different internal design then the stock 244 one could that have something to do with it?

curious as to where the temp gauge was sitting when you thought the engine was 'overheating'? i know sometimes mine goes all over the place from
dead low or not at all to just below the red zone at the top. i know it is the typical crazy temp gauge of volvo that is acting up, not
the engine that is overheating! now having said that, if the needle went all the way into the red zone i would stop immediately and check things out...

how much we want them to...
in the OP's case it seems this is a weak link in that system, but i still think the gauge is acting crazy/giving false readings. this is a well
documented problem...

Generally true with electrical parts but I never heard of a water pump problem such as this! One very rarely sees Volvo OEM water pumps anymore. It is just defying all logic. Was the pump just replaced before the overheating event? it's not clear from the post. If this is the case, then may be it is related to the pump but even then I'd say it is perhaps an air bubble... I do believe though that he has an overheating problem, not a gauge problem.

OK, that settles that.
I'd take it on that same run again and see if you duplicate what happened. Verify that it is indeed hot if it goes to hot on the gauge. Make sure that the coolant is topped off. That's what I would do... If it does that same thing then take a leak down test, may be a compression test too. Or you can do the tests now before further trips... May be easier if you have access to the gauges.
