VP 2002 Heat Exchanger

Hello, I have a heat exchanger (hx) that is leaking internally, loosing coolant. I don`t want to pay $3200 to $4200 for a new one from Volvo, I did find one from Mr. Cool for $1400 delivered to Nova Scotia not bad but a lot of other pokers in the fire. My question to folks here is...Would it be ok to leave the hx installed and leaking internally (no leak externally), install an anode and change the thermostat to a raw water cooled version and run the engine as a raw water cooled. I know I can change some piping and bypass the hx but that alone is $600.00 form Volvo. Any suggestions would be appreciated.

Check out https://lencocoolers.com/lencocoolers.html.

You don't need a Volvo specific cooler, and their general purpose HXs are excellent and less expensive. I used 2 on a 2003T (Hx and Oil cooler). Takes a bit of fiddling, and a slight mod to the coolant pump (thread for a hose adapter) and mount off the engine, but it was all a piece of cake. They are great on the phone and can help you spec one the correct size for the 2002.

Re: VP 2002 Heat Exchanger

Your VP 2002 heat exchanger is a bronze outer housing with a copper internal tube stack. It has 2 rubber end cover seals(different).
It is difficult to believe that it has corroded,but anything is possible.
Have you taken it to an auto/truck radiator shop for inspection/pressure testing?
I rebuilt mine VP2003 some yrs ago.
Cheers/Len


You would need to renew all of the rubber seals-pic attd

Re: VP 2002 Heat Exchanger

Thanks for the comments folks.
The issue with the he is while trying to remove the threaded rod that hold the end caps in place I damaged the soldered/brazed joints. The rod was corroded and stuck in the he and I wanted to replace it as the threads on the end were looking pretty worn.
I am part way through a partial rebuild of this engine that has sat for 4 years with out any love. Injector pumps, injectors, water pump">raw water pump and a sand blast and paint job are complete. The engine has less than 500 hrs on it so says the old guy I bought the boat from. I was hoping to bench test it before X Mass but the he has me stumped a bit, not wanting to spend crazy amounts of money on it.

My plan now is to put the he back together with a new threaded rod, end caps and seals. Plumb as it was, fresh water cooled. I know I will loose fresh water through the leaky he but if the engine runs well I will get an after market he in the new. year.

Any more ideas as to a good heat exchanger manufacturer?

Re: VP 2002 Heat Exchanger

As Deblen said, take it to a local radiator shop. They can probably fix the leak and you will be back in business!

Re: VP 2002 Heat Exchanger

Has anyone from Canada ordered a Mr. Cool heat exchanger? I am wondering if there will be extra duties at the boarder?

Re: VP 2002 Heat Exchanger

If the product was "made" in USA or Mexico,there is no duty under NAFTA.
You will have to pay 15% HST on the Can.$$ value.

The worst expense is the shipping across the border. Any of the major couriers(UPS-FEDEX/DHL,etc) will bring it from anywhere in the USA to anywhere in USA,(overnight),such as a border town,like Calais,Me. for $20US. You can personally pick it up there & import it free of duty but you must pay 15% HST.
If you have it delivered to a place in Can.,the courier charges you for US shipping $20 + customs brokers fee of min $50 + min $50 "handling fee" + shipping from Windsor/Mississauga,etc ,Ont to you for another $ 50 or so. 15% HST is also added to these Cdn. shipping services.
If you can get the US shipper to send it USPost & Can.Post(most don't want to put in the extra effort),you can save substantially,but it takes 3wks(3 days in US + 18 days thru Can.Customs & Can. Post.
Ask me how I know.
Your best bet may be to get it thru a Cdn. Distributor-pay same cost but let them handle shipping.
I will try to post some East Cdn. sources.
Cheers/Len

Re: VP 2002 Heat Exchanger

Which engine do you have? I actually have an md2040 full heat exchanger in storage from our old engine. It was replaced and only ran it for one season.

Re: VP 2002 Heat Exchanger

Hi Confianza, my engine in VP 2002. I am not sure if it would work? Maybe there is someone on here who will know if I could make it work. I am pretty handy and resourceful when I can save a buck.

Re: VP 2002 Heat Exchanger

So I ordered a HE from Mr. Cool. Crazy amount of taxes, fees, duties and broker fees to ship a part to NS, Canada. The heat exchanger is 600.00 in the US by the timenI get it here in will be right around 1600.00. The price of dreaming I guess. Looking to bench test the VP 2002B shortly.

Re: VP 2002 Heat Exchanger

I agree Len, small price to pay I guess.
Delivery on Dec. 05, hopefully start over holidays.
